Title: The Amazing Super Duper Underrated HD650. A Headphone That Kicks Serious Ass.
Post by: Marvey on May 15, 2015, 04:39:23 AM
The Amazing Super Duper Underrated HD650.
A Headphone That Kicks Serious Ass And Should Be Considered Before Any Other Thousand For Multi-Thousand Dollar Purchase.

I cannot emphasize how good this headphone is, even for those with a lot more money to spend. Sennheiser veil? Dunno anything about that. This is 2015. I purchased these HD650s from Amazon a few weeks ago. We aren't in 2007 anymore.

I decided to pick up the HD650 because I wanted something a bit different than the HD600s. More of a return to the slightly dark sound that I've always preferred. By slightly dark, I do mean slightly dark. A gentle downward slope. Not rolled off to shit. Also, if there was one thing that bothered me about the HD600, it was its slight vocal harshness, a bit shouty at times. This characteristic of the HD600 didn't do any favors with the mastering of the second and third Taylor Swift CDs. The idea of my actually buying the HD650 originated from my working at EC. Craig doesn't have any super headphones (I was too lazy to bring my own into the workshop for two weeks), so the best stuff on hand were the HD600 and LCD2r2 (special cherry-picked edition). I found myself using the HD600s the most often to assess sound quality. So I ended up purchasing the HD650 variant for the reasons mentioned above.

I don't exactly know what the differences are between the HD600 and HD650 drivers outside of a slightly different FR, but it does seem like that the HD650 driver is better damped, more controlled, more refined. The HD600 driver sounds looser - less controlled. What was surprising to me that some of the older HD650s had a depression the upper mids and similar bass, but this one wasn't like that all at. This HD650 had a very similar FR response as the HD600 outside of a slight bass elevation around 100Hz. Maybe this is why people who heard this particular HD650 didn't think it sounded veiled at all.

This latest HD650 has semi-transparent driver that you can see through. There is a semi-permeable baffle (see third picture down) extremely similar to the HD800 metal mesh material. I assume this baffle material does quite a bit to maintain low bass extension. The Sennheiser engineers are pretty amazing. I did few tweaks (not invented by me, but can be seen all over the Internet) to liven up the HD650s sound. The tweaks don't change the measurements that much. The measurements pictured are with these tweaks in place:
With the tweaks, the HD650 sounds faster, crisper, more lively, less over damped. I would not attempt these tweaks on the HD600 though. Overall, maybe a few db too much mid-bass, but everything else sounds just right. (I would ignore the roll-off past 10kHz in the FR graph, it's a measurement thing with how the microphone is angled on the measurement system.) Recordings which are a little bright like Midnight Oil Diesel and Dust are indeed a little bit bright. Recordings which are laid back like Natalie Merchant Tigerlily are laid-back, but not rolled off to shit. Taylor Swift's voice is a bit shouty, but not unbearably so. As I've said - just right.

Currently, I've got the HD650 hooked up the Theta Data III / Yggy / Zana Deux Super and have been enjoying it every night since I came back from the Bay Area meet. This is a fantastic combination that is easily end-game for most people. I know it's a little bit odd with me talking about this $300 mid-fi headphone, but I assure you this headphone is anything but mid-fi. Yes, the HD650 does belong in an obscene TOTL type rig. It's rather funny because today I received a PM:

Hey if you get a quick chance, I also wanted to hear your thoughts on the HD-650 vs LCD-3 for details. I'm hearing much, much more with the HD-650's, and it is making me think the LCD's will never offer the same presentation. The 650's seem to be presenting much more micro detail and I'm hoping I can take the LCD's to that level. Do you think it's possible with the right setup?

Here is my response:

It's funny you mention the HD-650. The latest HD-650s are really fantastic and IMO a superior headphone to the LCD-3F. The new Fazors are actually a downgrade from the older non-Fazor LCD2 and LCD3s. Yes, they sound worse. I know because I have an old LCD-2r2 non-fazor which has better transient response and faster less muddy bass than anything Audeze currently produces. The HD-650 is an extremely resolving headphone that doesn't get enough credit. Best kept secret for just over a few hundred bucks. It keeps scaling and scaling, even with a resolving DAC and amp - even up to the $7k amps that EC makes.

So I'm pulling your chain right? Nope. You guys have to remember that this is Changstar. We won't sell you guys on thousand dollar headphones if they do not perform. So before any of you guys drop serious money on headphones, seriously consider the HD650 with a good amp and a good DAC. And BTW, traditional dynamics, especially the Sennheiser dynamics, tend resolve better than most planars. They don't sound as clean, they aren't as fast, but they do resolve better. Something to keep in mind if you have Yggy.

Very nice write up. I have always wanted to own either the HD650 or 600 but never pulled the trigger as I find the AKG cans a more comfortable fit for me.  I have always liked both the 650 and 600 when. I have listened to them but my tastes leaned slightly toward the 600.  Question. Which do you think would be more complementary of the AKG K7xx that I already own (I have the Q701 as well), the HD600 or the 650. Maybe I should just get one already unless you think having the K7xx is too similar. Thanks.

edit: I also have the Oppo PM-2 which I felt was a bit 650'ish so again wondering if 600 might be better alternative to me as good as you clearly think the 650 are.  But I am game for either at this point.

Post by: Marvey on May 15, 2015, 04:50:17 AM
If you have K7XX, get HD650 for a darker sound. Pull and flex the headband apart for a looser fit. Clamping force was a bit too much for me when brand new out of the box.

As for PM-2. Quite frankly, all we've had new in the past several years are planars / orthos. I'm getting sick of them you know? (Nothing against the PM-2, it's a fine headphone.) There are some planars which are standouts, and I expect the HE-1000 to be one of them; but I am getting really fucking sick of more and more planars. TBH, I am a big fan of traditional dynamic drivers. There are few folks out there who are as well. Maybe we are in the minority, so consider this a counterpoint to the ortho revolution. The HD650 happens to be a masterpiece which has been continuously improved and withstood the test of time. Among all the overpriced expensive shit being hawked on the other site, this gem should not be forgotten.

I have maintained that an HD600 or HD650 (depending on personal preference), BottleHead Crack and a Mousai  MSD192 is one tremendous system for not an enormous amount of money.

Saw this thread, put away my HD 800 and using the HD 650 (with Wyrd, Uberfrost and project Ember v1). I can almost see why Marv recommends the 650 to complement the AKG7xx.

Pros: Awesome tone, especially for people more into the darker SR-007/Audeze presentation.  These love quality amping; I've heard some pretty killer HD650 rigs through the years.  Very involving, not much that irritates.  They also don't break the bank.
Cons: Definitely veiled compared to top technical headphones.  Bass is also quite wooly.

I don't think they're that underrated.  Everybody knows the 600/650 are great headphones, at or near the top in their price range.  They might not get as much pub as the new kids on the block, but they've stood the test of time and are generally regarded as a standard in the community.

This is probably no news (to a few). But overall, and price aside, I like the HD600s and HD650s more than the SR-007s, HD800s, DT-880s, AKG-7xxs and Audezes in their stock form.

    I have pretty new 650s, drivers look just like yours. Bought them directly from Senn. Non modified in any way except for stretched headband. Accidentally just listened to it this morning, after maybe 2-3 weeks break, out of properly warmed up Yggy/Rag combo. Good but nothing special and measure quite a bit worse then how yours appear to look.
   Circular cutout in front and absence of foam in the back sounds simple enough but why amazing engineers at Sennheiser couldn't figure it out for so many years of constant improvements, I mean seriously?  You know I trust your expertise but are you sure this pair didn't come in a golden box directly from their CEO? I mean Amazon must have some connections and maybe some secret agent out there is tracking all your purchases related to audio? :)p8
   All kidding aside, should I send you my pair for comparisons? Who knows maybe I have a lemon here and always misjudged all the 650s because of that? For about a week I had 1st generation 600s right before this pair and not much difference neither in measurements nor in listening impressions, there was no direct comparison though. Oh man, and how am I going to sleep tonight p:8

Yes;

HD6X0, K501, DT880. heard/owned them all and I always thought they were great headphones although I hate the DT880 due to the treble peak.

I always preferred the HD650 to 600/580 too.  650 si more refined IMO and I've the same problem than marv' with the vocal shout of he HD600.

At low listening volume, the HD650 is crap. At high volumes and tubes it's basically god.
But what isn't at high volumes and with tubes.  :wheel:

Yup, I love my HD650. Should have bought one long ago. My only advice is that stretching out the headband is good, but don't leave it stretched over something for hours on end unless you want to prematurely flatten your pads a bit too much. ;) Also learned the hard way that some Chinese pads won't attach properly, haha. That's what I get for trying to be cheap.

Love the HD600 and 650. I like the 650 more for being a bit darker, having no upper-mid, low-treble emphasis like the 600, and for generally being more refined. Mine at least is slower to show bass distortion than my 600 did at high volumes. The only thing I'd improve is smoothing out some of those wiggles in the treble and giving them more low-bass, though these can be a non issue with the right amp. But, really, it's about as close to my ideal headphone out of any I've tested yet.

Ahhhh... it feels good to see people who like the 650 a lot for once instead of people going apeshit about something Audeze's EL-8 at websites like HF. At an audio-show recently I had a good listen to the EL-8s and came out of that room frowning and confused because it sounded quite... bad (especially when I read a few raving reviews beforehand) then went to listen to a HD650 which put a smile on my face. I love the HD650s a lot for its warmish, dark-ish, slow-ish, naturally-decaying sound. It was the first "real" headphone I've ever listened to and will be my favourite for decades (I guess).  :)p1
I've listened to so many headphones since and none of them make me as happy as the 650 does although it may not be the most "technically" and "on paper" superior.
I wonder though, what and when this headphone will be replaced by Sennheiser. I see this headphone as a benchmark that should not be disturbed but kept. Sadly, since the HD700, I generally think that most headphones made by Sennheiser to be quite rubbish  poo
I'm afraid, since there are talks of a new high-end open back headphone being released later this year on HF.
Anyway, long live the HD650!

The other site can shill all it wants, people's ears don't lie in long term.
HD800 and HD6X0 have become seemingly quite popular.

From car analogy HD650 is like Saab 9-5 and HE400 is a Kia  :gross:
It is tempting for a novice to buy a new Kia vs a used european car in these parts of the world.

I don't have the experience or the ears that people have up here, as I am only audiophile level 2. I came to Changstar after being a bit frustrated with trying to find a headphone I could love. My HP journey started a few years ago when I purchased the vModa m-100. For a brief time I enjoyed them, but quickly got turned off by the big bass. Then I tried a few more cans, like Senn Momentums, PSB M4u 1, etc. Finally settled on the he-400s. I liked these for awhile, but soon the recessed upper mids and distortion in the mids started to really bother me. I gave them to my father, who only listens to classical, and they do alright for that.

When I came here and asked for advice, people recommended the hd600/650 with a tube. And purrin had a rig recommendation for these with the modi and vali. I was skeptical, like I had this idea that these were old school. But I picked up the hd650s about 6 months ago, and soon after the wyrd, modi 2, and vali. And omfg, this has been a life changing sound. These are really easy to enjoy. The tonal balance just drips with joy.

I am indebted to the people here who got me going with the hd650s.

Not trying to defend HF, but the HD650 is the highest rated headphone on there.

Love my HD650 too, but has Sennheiser continuously been updating it?  I've heard one revision when they change the foam from black to silver.

HF is so F(lavour) O(f) T(he) M(onth) oriented that sometimes it reminds people of a Starbucks where through the favours it is difficult to distinguish the coffee. At Starbucks  I only go for the flat white or filter brew.

HF became so annoying at one point that it reminded me of MSN without AdBlock. No more...

When I had them for a week, they lacked the kind of bass extension I was looking for, which was their achilles heel for me.  Seems like I can't be bothered with anything less than planar or hd800 levels of extension from an open headphone.

However, I did think they were amongst some of the smoothest and most neutral frequency response from midrange to treble, while only lacking some energy above 10-12khz.  I think the HD600 is a little less neutral throughout the midrange, unless it's on a warmish tube amp.  I did not find a veil on the HD650 (silver damping.)

I had one and got rid of it because I have a relatively bigger sized head - I could not get over the squeeze. I think I would want to buy one back at $299.

Messiahs how do you make the headphone less "clamp"? Extend the headphone to max size & hold the exposed metal plate and bend it?

Less clamp comes from more wearing time  :P

Or getting a used pair. You can also try carefully pulling the at the headband.

I have a pair that was from 2006 with the old drivers, and there is a distinct "veil" but even then it's a world-beater.

Last year I ordered a pair of the "new" drivers with some replacement pads. It was like night and day different, and a renewed interest in the HD650s.

Surprisingly, you can still buy parts--enough so that you can build one yourself.

My old HD650 has much less clamping force than the new HD600 I had for measurements.
The HD600 gave me a headache after a few hours. Never had that with my older HD650's not even when new.

Below the exact same HD650 (black driver) with original (softer and more compliant) pads and the same HD650 with a set of new pads.
This plot is only to show relative differences.

At the prices the HD650 can be attained for new today, it's quite a steal. I remember it was nearly impossible to snag one for $250 used a couple years ago. I've owned several of them in the past and I never felt like there was a veil, especially when paired with a proper amp. However, the HD800 does outclass it in almost every way, especially in resolution and spaciousness. I also tend to prefer a "warmer" signature, but the HD800 with Anax mods and Yggy bass/smoothness doesn't make me miss any of the HD650 "darkness". You can have your cake and eat it too, you just need to pay for the cake.

650 is still quite well regarded on head-fi and still has a large following, but there's a sickening habit and mentality to write it off as mid-fi when comparing it to all the high priced planars on the current market, primarily because of cost reasons and/or the idiotic 'summit-fi' subforum on head-fi.

I really liked the HD600s.
To me they were comfortable, well behaved and although it lacked a bit of bass slam for me, they did an Ok job with bassy tracks. Although, I have to say, I slightly prefer the HD598s!!! :o :o Blasphemy I know...

Never tried the HD650s and probably will not yet since I'm using closed-back most of the time. But if they are slightly bright up top (similar to the 598s) and I start spending more time at home, I might try them. Though they will have a hard time against the HE-560s which would probably be on the top of my list even if they are bright on the edge of being a bother... (I really liked the 560s when I had them for a bit.)

I've not heard it personally, and I sold my HD650 long ago due to comfort issues, but I've heard that the Fidelio X2 checks most of the boxes at half the MSRP.  Truth to the rumour?  They look pretty comfy in comparison to the rigid, plastic HD6XX.

I also liked the HD598s.  Much more comfortable with a more mid-forward sound.

Nice to see this thread!

I was telling Ravi that my favorite rig at the Bay Area Meet was the Yggy --> ZD Super --> HD600 (I wish the HD650 there was terminated to TRS). I found it much more enjoyable than the Yggy --> EC Studio --> HD800, given my preferences.

Realized that the HD800 just isn't for me, honestly. It is SO impressive on some levels, but I much prefer a HD650 for everyday listening. If I was listening exclusively to classical or LFF-remasters then it may be a different story.

A Geek Out --> HD650 rig has no business being as good as it is for under $500.

Nice to see this thread!

I was telling Ravi that my favorite rig at the Bay Area Meet was the Yggy --> ZD Super --> HD600 (I wish the HD650 there was terminated to TRS). I found it much more enjoyable than the Yggy --> EC Studio --> HD800, given my preferences.

Realized that the HD800 just isn't for me, honestly. It is SO impressive on some levels, but I much prefer a HD650 for everyday listening. If I was listening exclusively to classical or LFF-remasters then it may be a different story.

Actually, I agree that rig was amazing. It was my number two behind Yggy > EC Studio > modded HD800s

I've not heard it personally, and I sold my HD650 long ago due to comfort issues, but I've heard that the Fidelio X2 checks most of the boxes at half the MSRP.  Truth to the rumour?  They look pretty comfy in comparison to the rigid, plastic HD6XX.

I just got the loaner X2 in today. I think they're going for a different sound. HD650 is relatively neutral but with a gentle downward slope (i.e. slight darkness) and a bit of a mid-bass emphasis while not having the most powerful low end. X2 is immediately bassier...just way more powerful sounding in that regard. Mids aren't as lush, and treble not quite as well integrated. In that regard, sounds more U-shaped, but mostly because of bass. Treble has a hint of extra brightness, but, as a whole, mids and treble are pretty good on the X2. Just dat bass is big and on the thick side. I have to say, though, the X2 might have a better soundstage (HD600/650 being a bit too left/right at times), does a pretty decent job with details, but likely won't scale nearly as much and isn't quite as fast sounding due to the bass. It is certainly an engaging listen, but I think it and the HD650 occupy different spaces.

Comfort wise, HD650 clamps more out of the box. X2 clamps too, but doesn't start hurting until later on. Both are fixable and equally comfortable after doing so with me giving a nod to the X2 in overall ergonomics.

My impressions of the X2 are pretty much the same as Hans'. The X2 is much bassier and slopes down harder before the first treble blip, giving that V shape sound. I think the HD6xx are cleaner overall. Personally I give the comfort nod to the X2.

Out of the box for a casual listener, I think the X2 would be preferable. Extra points for not needing an amp, and it doesn't really scale much.

Haven't heard the Modi but I had the Vali alongside the Mjolnir for some time. Both amps were hooked up to my NAD M51. The Vali held its own against Mjolnir. Main differences were more slam in the bass region from the MJ and a slightly wider stage. I found the Vali a touch smoother though, with that slight tubey sheen/ambience that seems to marry well with the HD650's signature. The Ragnarok I have now provides the best of both amps.

I just tried doing the mods that Marv suggested on the first page. That is, removing the damping directly behind the driver and cutting a small hole in the foam in front of the driver. Highly recommended! This doesn't really improve the very lowest bass all that much, but it does bring up that hump centered around 100Hz a tad and may even shift it down a bit closer to 80Hz. They sound much more lively and impactful now in this regard. This also really helped with some of the odd grain I noticed in the treble before. I noticed before when adding damping inside the HD650 cups (in addition to the stuff directly behind the driver), it did something weird to the treble despite measurements looking good or staying about the same in the upper regions. I was actually using additional front damping before this to boost the bass and help reduce that grain I noticed, but removing the back damping foam stuck behind the driver works a LOT better and actually allows one to cut down on the front damping from the stock config. So, in a nutshell, try the mods on the front page.

One small thing I added to these mods, though, was putting some rug liner on top of the silver mesh surrounding the driver, under the existing foam. This is only cut to cover the mesh, so it's much smaller than the foam, and has an opening in the middle where the driver is exposed. Essentially, this boosts the bass a wee bit and helps smooth out some of the "wiggles" in the treble. It's a very slight change.

Attached a quick measurement of the left channel after these tweaks. My particular HD650 has better distortion in the bass than my HD600 did, but it's still not the best I've seen. Still could do a lot worse. My pads are also a bit worn. New pads will lower the bass a bit and bring up some of the treble.

I once tried replacing the foam cover with thinner panty hose fabric cut to the same shape. It made the HD650 a touch more lively but I didn't appreciate the slight etch that surfaced.


The odd grain in the upper regions that hans mentions has irked me at times with the stock HD650. I might give Marv's mod a trial later. What's the diameter of the hole you cut in the foam?
Title: Re: The Amazing Super Duper Underrated HD650. A Headphone That Kicks Serious Ass.
Post by: Hands on May 16, 2015, 03:47:00 AM
Yeah, I took some brief measurements without the front foam. Bass dropped a lot. Treble got a bit weirder. Didn't even bother listening.

So, yes, try the mods Marv mentioned in the first post. I don't know what the diameter of the hole was...I just put the HD650 under some light and drew a circle over in marker where I could see the driver opening (very middle portion of the driver). Cut it out from there with everything disassembled, to prevent foam crap from getting in the driver opening.

If that's still not enough in terms of that slight, hard-to-explain grain, try the liner directly over the silver mesh and under the stock foam. Might help.

For cleanly cutting a hole in the foam:  I used to take a hammer w/ a socket wrench bolt (that's roughly the size of the driver opening) to the foam.. easy peazy.

I Love my HD650's! Best headphones I have ever owned. I do not have them modded or anything, but to me they are stellar with my setup (A huge thanks to purr1n and Gunner for recommending those to me over a year ago - they was right on as usual!). I just have a modest setup too. Just running the following:

JRiver Media Center 20 -> Uberfrost (with Gen 2 USB upgrade) -> Valhalla 1 or 2 (depending on mood) -> HD650.

So just a mid-grade setup as far as gear goes, but thanks to purr1n and Gunner (who basically suggested all of the gear that I have) I am extremely happy with my setup. Now I just need a better DAC - ahem... Yggdrasil (probably never going to happen at that price point for me  :-[

My point is, I am extremely happy with what I have and I feel very fortunate to have great friends with great knowledge here at Changstar to help point me in the right direction as far as gear goes with my budget - a huge thanks to all of you!

I really want to try the mod that purr1n posted in this thread, but I have never disassembled headphones or modded any headphones before, so I am a bit nervous to try to do the mods, especially since the HD650 is the best headphones I own,  but I really want to try those mods!

Do people find the HD6nn to be position sensitive? (or am I asking a newbie question: maybe all 'phones are?)

Even after a few months (although I don't listen daily; sometimes not at all for days) I recently found that moving the band forward on the head not increases the comfort by moving the phones off the jaw, but also seems to give better treble.

The downside is that the band presses a little more on the top of the head.

For the thin of face: comfortable out of the box. It does get a bit hot in there. but my ambient is 28-30C (82-86F), tropical-humid, so it's hot and stuffy inside my ears without headphones!

I think it's like that with most HPs.

The pads will compress with wear, and that too change the sound.

People will go to crazy lengths to get things just right.

I have not tried the quarter method yet, was thinking about it though. I am just a little nervous because I have never modded a headphone before, I am scared I may accidentally puncture the driver or something, unless there is an easy way to take the foam covering the driver off by removing the earpads. If I were to try the quarter method, I like hans idea of drawing a circle around the driver (with the foam still on) then figuring out a way to remove the earpads and take the foam covering the drivers off - then cut the hole in the foam that I drew using hans method, then replacing the foam and earpads. I do want to try the complete mod that purr1n posted, I am just too worried that I would screw something up. I have no idea how to remove the grills without bending them, and even if I did remove them, I would be afraid I wouldn't be able to get them back on. But if you just want to try the quarter method, and you know how to remove the foam covering the drivers, you could use hans method of drawing a circle around the driver before you remove the foam, or you can remove the foam and use the quarter method purr1n described then simply replace the foam.

On the HD600 (same design from my understanding), the foam is just an insert that overlays the driver, and is clamped in place by the pad. You should just be able to pull the pads off and remove the foam to cut it. If you haven't removed the pads before, they just snap in place. You can place your fingers along the inside/bottom interior of the pad and gently pull it away from the headphone...it will just pop off.

Not a problem. As for the grills: Remove the headphone cable. Gently pull the trim piece that the cable plugs in to (the separate piece that matches the yoke) away from the headphone body. The grill just pops off as well.

That would be awesome hans, thanks to JoelT I was able to get the earpads off and access the foam, but I am still a little nervous about popping the outside grills off. Also, as far as making a whole in the foam to expose the driver, I was going to try either the quarter method, or the method yuo described hans as far as drawing a circle around the driver. My question is, what tool should I use to cut a perfect circle in the foam like the one in the photos? an X-Acto knife? Or is there an easier way?

And thank you hans for offering to post step by step instructions, it would help me out greatly since I have never modded a headphone before and since these are the best headphones I own, just a little nervous - so step by step instructions and pics would help out greatly -thank you hans and thank you JoelT.

If you change the scales, zoom the plot, go down to 10 Hz, and add an 009 as reference:

(http://www.changstar.com/index.php?action=dlattach;topic=2415.0;attach=9584;image)

The < 20 Hz response may be pessimistic in my rig (and considering 6x0/580x where leaky measurements vs 009 sealed measurements). I usually limit my measurements to 20 Hz to 20 kHz.

Oh, I just used regular scissors and took my time cutting. It's nice that you can just pry the ear pads off without much worry. I use a spoon to pop the grill off. There's a little, uh, dip or recessed spot around the side of the cups in the back where you can pry the grill off. Grill does have a plastic lip around it, btw.

I used tweezers to get the back foam out. Carefully push it in from the sides first. Some spots are glued on, so lightly push over those spots until the foam comes loose. Be gentle so you don't get foam inside the driver area. Once all the edge spots are free and pushed in toward the center, you can pull it out gently from the top opening.

Thanks to all of the great posts and guidance here in this thread I was able to successfully do my first headphone mod ever! I was a little nervous since the HD650's are the best cans I personally own, but with the detailed instructions in this thread I was able to do it - and boy they sound great! I agree with purr1n,  with the mod they sound crisper, more lively, less over damped. And maybe it is my imagination, but it seems the sound stage is a bit better as well.

I want to thank purr1n, hans, ultrabike (great video), and JoelT for all of your help!

Below are some pics of my HD650's modded going by this thread's instructions - Please note the first 2 pics are not mine, I found them online to help others who want to mod their HD650's on how to use the tweezers method to remove the foam from the back of the driver behind the grills - the rest of the pics are mine (sorry my camera sucks)

Thank you again to all who provided extremely useful information and tips to mod the HD650, I love the way these sound even more now, and purr1n was right on with his impressions!

Let me know what you guys think, I know that the holes I cut over the drivers inside the ear-cup are not perfect, but this is my very first time disassembling any headphone or modding any headphone and I was really nervous as these are the best headphones I currently own. Does everything look ok to you guys? I know the holes over the drivers aren't perfect, but did I do it right?

The HD650's were one of the first headphones I ever owned.  I spent some time trying to "upgrade" them and find something I liked better.  I went through the Q701, HE-500, T1, HD800.  Eventually I gave up, and just decided to buy an "end game" amp for them which was the Zana Deux SE.  I couldn't be happier.  While I still maintain the HD800's and enjoy them, if I had to chose between the HD650 and HD800 the HD800 would lose out.  I'd image that most people don't pair a $2000 amp with a $300 headphone.  It's really something special though.

If it's any consolation, I completely fucked up one of the foam cushion thingies when I tried to do that mod. So right now I'm riding foamless. Luckily, I've an extra set of pads inbound anyway. And I ordered two replacement pairs of the foam cushion thingies off of eBay.

Managed to get the foam off the back of the driver, however. Don't think that mod is reversible in my case: The foam was really glued on/stuck at certain points and thus was damaged in the removal.

Wouldn't surprise me. HD800 doesn't scale much if any on the ZDSE. You should get a ZD Super sometime or have it upgraded to a Super. I hated the ZDSE and made sure to tell Craig every chance I got. Unfortunately, I can't do that anymore.  :'(

Buy an HD600 and order HD650 drivers, or vice versa. (The HD600 is cheaper and the HD650 drivers were actually cheaper than HD600, last time I checked.) You can easily switch them in a few minutes. I put 650 drivers & grilles in my 580.

Or just buy the 650, leave all audio forums and don't worry about it ever again.

The HD650's were one of the first headphones I ever owned.  I spent some time trying to "upgrade" them and find something I liked better.  I went through the Q701, HE-500, T1, HD800.  Eventually I gave up, and just decided to buy an "end game" amp for them which was the Zana Deux SE.  I couldn't be happier.  While I still maintain the HD800's and enjoy them, if I had to chose between the HD650 and HD800 the HD800 would lose out.  I'd image that most people don't pair a $2000 amp with a $300 headphone.  It's really something special though.

Not sure where the Ragnarok fits in the scheme of things as hype seems to have died down, but both the HD650 and HD800 sounds magnificent through it. I love the HD650, but it's no contest through my system. The clarity and precision imaging of the HD800 is in another league and I'd be loathe to part with it to only slum it with the HD650.

The stock cable that comes with the HD650 is a standard stereo cable with 1/4" gold stereo plug. You can purchase after-market balanced cables for the HD650 though. (If I understand what you're asking correctly). 

This is an expensive one (the Sennheiser brand) - but you can find them much cheaper - but are you looking for a cable like this?

actually my question was about the the pins that connect into the headphones (those 2 pins you see on the other side of the xlr plug) I think it might be a positive and negative pins but not sure.

Post by: The Alchemist on May 17, 2015, 05:01:43 PM
AH ok I understand what you are asking now. The reason for the two pins are one large one for ground, and a smaller one for signal. These are inserted into the headphone and a small spring within the cup conducts the signal and sends it along some very thin wires to the driver.

Wouldn't surprise me. HD800 doesn't scale much if any on the ZDSE. You should get a ZD Super sometime or have it upgraded to a Super. I hated the ZDSE and made sure to tell Craig every chance I got. Unfortunately, I can't do that anymore.  :'(

Unfortunately EC won't re-work my current ZD SE to a Super level.  I'm trying to find out if they'll send me the parts so I can do the upgrade myself but I'm pretty sure that will be a big no.  I've only had it for a few months so it kind of sucks that I caught the tail end of the outgoing model with no option but to sell and re-buy if I want the new one.  Now that the new one is getting rave reviews, I'm sure that won't help the secondary market for the old one.  Bad luck and timing.  I can understand why EC wouldn't want to re-work old models as it would probably be a process change for them.  All of that aside, I think the non-Super ZD SE does wonders with the HD650's which is why I bought it in the first place.  The sound stage and the treble energy in particular.  No other headphone has continued to scale as well as the HD650's.  Going from a portable amp/dac, to OTLs (crack and La Figaro 339) and then to ZD SE, the 650's just keep on giving.

If you got yours a few months ago, you might have some of the changes already. There have seen some revisions and tweaks over the span of some time. I would say if you like the tonal balance of your current setup with your existing tubes, keep it as it is.

I haven't had the opportunity to listen to the HD800's on a lot of other amps.  Going from the crack+speed ball to the ZDSE, the improvement/difference with the HD800 for me was take it or leave it.  Same with the T1.  However, the difference with the HD650's was very apparent.  Full disclosure though, I'm not a very good critical listener and I have much more experience with the HD650's than I do with the HD800's.

My "high end" in headphones started with the HD580 paired with the Musical Fidelity X-cans in 1995. They were then TOTL dynamic and the Jubilee edition was released later in that year. I have always had fond recollections of those headphones and I recently decided to pick up a pair of HD600, somewhat out of curiosity and somewhat out of nostalgia.

I was a little disappointed in truth, the memory far outlived the actual performance. Either my expectations were unrealistic or my ears have become so attuned to planar attributes but they sounded very mediocre of any number of amps I tried them on. It is not that I think they are awful but just not as good as most any of my other headphones. Unlike Purrin, I have sold my musical soul to the planar world. I can enjoy dynamic headphones for a short period but I most always end up looking for microdetail which I find in the planars but not so much in the dynamics. The HD800 behaves more like a center pinned planar than a dynamic , or more appropriately, center pinned planars behave more like a ring radiator. either way, I do not think of the HD800 as a typical dynamic headphone.

My intent had been to try and mod them as I was able to give new life to my K501's . There is hope but thus far the 600's have not shown me the great promise of a modern TOTL killer.

Why are so many headphone makers still putting out crap when it's been more than 20 years since the HD580? You would think they could reverse-engineer that and put it in a cosmetically different frame, if they can't come up with something better themselves. Is there some magic trade secret in the manufacturing process?

By the way, are all the bumps in the 650 treble response real or some sort of measurement artifact? Personally I've found the 580 and 650 treble to be a little irritating and not as refined as a good modern speaker, but I've wondered if it's just "revealing bad recordings" or something.

Headphones have good dynamics without breaking the bank, (as opposed to speakers where you have to pay for quality and for quantity & bass) and they avoid room acoustic problems, but personally I think speakers are generally better. Most are garbage compared to speakers, and the best such as the HD650 still have some flaws. I don't buy this "headphones sound as good as speakers at 10x the price" that people say.

I think it's a shame Sennheiser and others don't offer amps with EQ to fix the Senn midbass hump or other flaws, like solderdude is doing with his Sennator. Bose and others use EQ to improve the sound of their noise-canceling phones as can be seen in the active-vs-passive-mode plots at Innerfidelity. They shouldn't leave it to the customers to cobble together solutions. I would think that EQ would make it simple to fix certain problems, where physical changes to a driver might fix one problem and create others at the same time.

Can you paint the grills on the HD650's? I was thinking a candy apple red color. Since the grills are detachable, if you paint the grills, would it effect the sound?

I don't think any any manufacturer is going to sell an amp that fixes problems with their headphones. Manufacturers don't like admitting problems like that!

For those of us whose music comes from computers, EQ is so easy, and probably even included in the media player. We can do out own. Wait, did I say, "easy?" Hmmm... access to the tools is easy, getting a really good result might not be.

I asked this question in the ZD Super thread, but sadly no one would answer my question so I'll ask again here, seeing that people here are also taking about the ZD Super and how it matches with HD650 and HD800.

The ZDSE, which I had owned but sold in lieu of ecp L-2, was a great sounding amp and according to many gurus out here the warmest, most euphonic sounding of the EC lineup. However, despite its warm signature, it ironically had a bright treble peak that didn't do the HD800 any favors.

My question is, aside from sounding superior to the ZDSE across the board, does the ZD Super address its predecessor's treble issue and smooth out the bright sharp sibilance of the HD800 much better? Or is it still there and therefore not an ideal match with HD800?
Title: Re: The Amazing Super Duper Underrated HD650. A Headphone That Kicks Serious Ass.
Post by: CEE TEE on May 18, 2015, 04:07:01 PM
^Songmic...I had the original ZD and the ZDSE Super definitely addresses the peak and is more neutral/linear across the whole FR.  Just a touch of euphony or slightly relaxed, it is more neutral without discernable peakiness anywhere but also a touch drier than previous versions.

Post by: Marvey on May 18, 2015, 04:25:18 PM
@songmic: Sorry, I saw your question earlier in another thread but forgot to answer it.  The stridency was something I also heard with the earlier ZDs. We did a few things to tweak it, namely the use of higher quality caps in critical areas. At this point, I don't feel the ZD is any more strident than the other EC amps, e.g. Studio.

Keep in mind that driver tube will matter. We ran a less warm more neutral 6SL7 at the Bay Area meet. The warmth of the old ZD can still be obtained with the right tube.

It looks like you have the new output caps and PS circuit, but not the feedback circuit tweaks. The new ones have less feedback, minor tweaks there, and slightly higher output impedance ~20 ohms at the H position.

There you go... these LCD's have really put me off chasing the next best headphones...

Also, I don't want to sound like I'm jumping on the Yggy bandwagon hard, but going to the old Angstrom 200 dac was night/day for me with my 650's. It somehow cleans everything up, resolving even more detail, and fixing the treble. Cymbals/percussion sound correct, more like a turntable setup and less like digital crap. (I'm not a hater and much prefer FLAC for the convenience anyway, but this sweetens the deal even more).

Will hear the Yggy in a couple weeks and see how it sounds in comparison.

I understand this.  Right now I have a system where the HD600 is just sublime.  Tonality, musicality, layering, detail, weight.  Where my modded HD800 seem more resolving and the headstage is bigger, the HD600 present everything closer, more intimately with more L/R stage but layers and a pleasing "thickness" without anything bothering me.  Another surprising step for the HD600 and why it won't go anywhere (again). 
The HD650 with Marv's latest mod tempt, but I'll wait and borrow or compare later.  Bill just measured my HD600 and ultrabike did some time ago, so I will have a couple of graphs to compare to Marv's modded hopefully sometime soon.  I wouldn't be surprised if they are pretty darn close.  But, the HD600 can also be harsh and not that pleasing on some set-ups.  The early HD650 were always too veiled for me, then I started hearing much clearer pairs.  Very interested in these again now.  Will they beat HD600 for me?

The HD650 arrived. This one does not sound as dark as the HD650s I remember from multiple auditions in years prior. In fact this one sounds pretty close to my HD600 but with a bit more bass sound level, not necessarily any difference in quality. Puzzled I am.

yeah I am looking at bills measurement of the cee tee's hd600 and I don't really see that much different from the Purrins measurement. 

The Amazing Super Duper Underrated HD650.

 Also, if there was one thing that bothered me about the HD600, it was its slight vocal harshness, a bit shouty at times. This characteristic of the HD600 didn't do any favors with the mastering of the second and third Taylor Swift CDs.

I don't exactly know what the differences are between the HD600 and HD650 drivers outside of a slightly different FR, but it does seem like that the HD650 driver is better damped, more controlled, more refined. The HD600 driver sounds looser - less controlled. What was surprising to me that some of the older HD650s had a depression the upper mids and similar bass, but this one wasn't like that all at. This HD650 had a very similar FR response as the HD600 outside of a slight bass elevation around 100Hz. Maybe this is why people who heard this particular HD650 didn't think it sounded veiled at all.


purrin when you said this about the hd600 were you using a recent pair?

But, yea, I can definitely see why the hd650 can be under appreciated compared to other headphones in its given price range.

purrin - Do you consider the HD650 more resolving than the LCD-2? My last Audez'e was a pre-fazor LCD-2 rev2.5 which sounded more refined than my first LCD-2 and - to my ears - in a tier above the HD650 in technical terms. It was smoother, faster and more resolving, particularly in the lower bass region. I conceded that the HD650 was inferior but I did end up preferring the HD650. It's almost inexplicable. Perhaps it was a combination of comfort, the wider soundstage and more textured layering of elements that made the HD650 a more engaging listen. I found the Audez'e a relative bore despite that clearer window into the music.

To me they seem less damped and more "alive" - and on my particular setup, even the sound stage sounds a little better. The great part about this mod too is that it is easy and cheap to reverse the mod (the foam behind the driver under the grills may be tricky) but you can easily and cheapy replace the foam on the inside of the cups over the driver. Great mod for my tastes.

I wouldn't doubt they are very good as well. The only sennheiser in the 5xx series I heard were the hd558 and found them to be extremely good to what they offer in their respectful price bracket. Lately though I haven't got around much with headphones. Harder to come by locally compared to speakers for testing/auditioning.

Compared to Craig's A grade LCD2r2, I'd say Craig's Audeze is about even. Audeze wins in the bass, transient response, clarity. HD650 wins in overall frequency response, liveliness/openness. Resolution is about even until an EC tube amp + Yggy, where the HD650 slightly overtakes it.

Yes, more lively, more open. The HD650 seemed a bit too damped. I will post pix later, but I found the foam discs squished in back of the driver decompressed into three separate discs. This allows for some tuning. I may decide to stick one of the foam discs back in.

Volume levels are about the same, although the scale types (log) are the same. Note that D2 is very different, with 'Tode's pair having D2 well above D3,D4. Has Senn been implementing silent upgrades? Perhaps lessons learned from HD800? This might explain a lot why the folks who heard this particular pair heard no veil.

Do you think that replacing the 600's drivers with a 650 driver could improve things in that regard without shifting the FR?

HD650... http://headphonespares.sennheiser.co.uk/hifi-tv-headphones/hd-650
capsule  part #092855

So they're different numbers, but the capsules are the entire baffle/driver assembly. I'm not sure if the individual driver element is different, but that's as much as I could dig up.


edit: same numbers here: http://www.custom-cable.co.uk/headphone-spares/capsules/

Right. 558/598 use the same driver but different baffles so different part#'s. I imagine same practice here. Could be wrong.

FWIW, my HD650 has better measured bass distortion vs. the HD600 I tested at the same SPL. Tyll's HD650 measurements also showed ever-so-slightly better THD on the HD650 vs HD600. When I was experimenting, FR changes with/without this thread's front-page mods primarily affected mid-bass but otherwise were relatively slight differences beyond that. Playing around with damping material beyond that, even going so far as leaving the back damping in place and removing all front damping, still doesn't get results quite like the HD600 (i.e. upper-mid/lower-treble slight emphasis), and the housing appears to be about the same if not identical on both models. I could be wrong on that latter point.

I have to assume the drivers are actually slightly different or at least cherry picked in some way.

Another tweak that might work is putting lower desity open-cell foam sheets in the cups after removing the stock back damping. This should help reduce mid-bass while still providing a more subtle effect vs. putting something directly behind the driver. Just a guess, though. Lower-density or less foam directly behind the driver should work too if you want something in-between. With the front-page mods, though, there is occasionally a smidge too much mid-bass, but I usually just enjoy it for what it is. I generally like some extra (measured) bass or mid-bass myself anyway unless the driver inherently has a ton of bass slam, which I usually only find in planars with huge drivers.

Anyone else decide to do the HD650 mod that purr1n posted in this thread besides me , purr1n , and hans, and if so, what do you think? I agree with purr1n. To me they seem less damped and more "alive" - and on my particular setup, even the sound stage sounds a little better. The great part about this mod too is that it is easy and cheap to reverse the mod (the foam behind the driver under the grills may be tricky) but you can easily and cheapy replace the foam on the inside of the cups over the driver. Great mod for my tastes.
I completed the mod today after getting my replacement pads which came with the foam inserts. Used the quarter and blade method recommended by purrin. Now, I got the HD650 late last week, so I never merged with the stock sound. Which probably makes my impressions more or less useless. However, I can say something like this: I have the sense of an improvement with respect to attack - like it hits harder and quicker. This could contribute to an increase in perceived liveliness. But I'm still learning my words.

Can someone suggest a good balanced cable for HD600/650?  Thinking of picking up a pair after hearing them at a meet a while back.  (Now I understand why they are an icon among headphones!)

Using Ranarok as amp so balanced is strongly preferable.

So I've been listening to the HD650 acquired this week given the latest Amazon price drop. These are NOT the HD650 I heard several years ago.

My HD600 have been a constant over the years, with the HD580 for a considerable time before that. The past HD650 had more bass but sounded thick and dull to me compared to the HD600, tested on various amps. The HD650 to which I am listening today are neither thick nor dull. They sound very very good. In fact I have been listening for more than four hours today (a recreational listening day, yeah!)

The last two hours have been with a Mousai MSD192, Project Sunrise III with PSVane 12AU7, output set for 32 ohms. I will be wanting to do a system level set of measurements to find out why this modest setup sounds so good to my ears.

I'm thinking I will do a shootout of new HD650 vs my (late 2014) LCD-3F.  I really enjoy the sound of the LCD-3F (I think I have a good pair?) but the comfort issues are wearing me down over time.  I can only wear them for maybe 30 minutes before the "hotspot" in the middle of my head starts to annoy me.

Keep in mind HD650 stock cable has an enamel coating and a string of teflon in the conductors you will probably have to deal with.

Teflon strands I try to separate from the conductors and use a small pocket knife scissor to snip.

The enamel you should be able to get a glob of hot solder on your iron first and use it to burn away the coating; once it melts/bubbles away the wire should begin to tin.

Got my HD650s today.  Nice, but not as good as my Lambdas.  I still don't remember exactly why I sold them before though.  Didn't have the Lambdas then.

My paper thin rationalization is that I need something to use when it's too humid for 'stats or while my hair is still wet from the shower.

A headphone for every occasion right?

Proly depends on what you are used to. I find the Lambdas inferior to the HD650s in many ways. The Lambdas are perhaps a tad brighter relatively speaking. I don't think the Lambdas are as resolving. Bass would definitively depend on cup fit and is lower than with the HD650s going by memory.

FWIW, I noticed that the quarter-sized cutouts from the foam inserts are roughly the size of the foam disk at the back of the driver. Since I more or less destroyed my foam disks removing them, perhaps I could use the quarter cutouts as replacements. Maybe could layer them as the originals were a composite of three disks.

I can understand people not liking the Lambdas for not having enough weight behind them compared to dynamics or orthos, or for being too bright, but calling them less resolving than the HD650s honestly just baffles me.  I can hear far deeper into the mix with a Lambda than the HD650.

OTOH the HD650 are still my favorites out of all the dynamics that I've had a chance to hear.  They manage to be exceptionally clean (above the bass anyway) and decently resolving without any 'fake detail' from sharply boosted treble and are free of nasty CSD ridges that force me to put them away after 20 minutes.  I'd guess a properly modded HD800 would dethrone them (despite it's other advantages, the stock HD800's treble has too much of a metallic timbre) but I haven't actually heard one yet.

Stock, the Lambdas I've heard do tend to be a little bit plasticky but my ears find that less offensive than the HD800's metallic tone and it's not too hard to mod away either.

Even throwing orthos into the mix, the only ones I'd take over an HD650 would be an A-Grade LCD2/3, and HE1000, or possibly a vintage T50 base model.  Most of the other HIFIMAN orthos didn't sound as clean as my modded T50RPs, and the ones that did (5, 5LE, and 6) had too much sharpness in the treble.

You might not like, believe or want to hear this, but if you are using an O2 to pair with them then that's one reason you could feel that way. My Leckerton even with the older 209 opamps slaughtered the O2 in resolution.

That would be the first time I've heard such a thing.  Except for my BH Crack (which has pretty obvious reasons for sounding different), they sound pretty much the same from everything I've tried them with.  300 ohms is pretty easy load for most headouts to drive, so provided you're happy with the volume they're quite widely compatible.

I can give it another chance and see if there's still room in the BW loaner tour.  Unless you wanna tell me my ODAC or Scarlett 2i2 are bad enough all the amp in the world won't matter...

I would like to thank Anaxilus for all the posts discussing the virtues of Leckerton. As a direct result I acquired a UHA-6S mkII. Initially I thought what a nice USB upgrade from ODac+O2. Then  I discovered the spdif input. You see, I bought an iBasso dx90. Now that was a reasonably decent improvement over my portable devices' native headphone output. But the dx90 has a spdif output. You see where this is going. dx90 as digital music server and Leckerton doing the heavy lifting. Now I have a portable system that kicks butt and takes names. Thank-you.

We need a better way to explain "resolution" to planar people...I think Marv, Anax, ultra and I all hear it but we keep running into this descriptor conundrum when trying to explain it.

Resolution is NOT macro-clarity. The Stax provide more of that due to their ultra-clean and synthetic plastic timbre. And possibly slight FR accentuation in the upper mids.

Resolution is NOT treble spikes that "enhance" detail. This isn't even worth addressing...none of us think Grados, AT's, etc. are resolving. You can't add resolution by EQing the treble up.

Resolution is NOT "speed". Things can attack really fast and then decay really quickly and evenly, but still be missing all of that musical information beneath and around it. Which leads me to....

Resolution is, as I have come to define it independently from what I hear as well as what I glean from others, the ability to portray information on the recording. The ability to render the picture/frame in its entirety if we want to use the video analogy. It's not a big leap to extend that definition to include both microdetail (plankton, inner-whatever, etc) and spatial information (ambient cues, precise imaging, etc.)

If we can all agree on this definition (feel free to add your interpretations guys), then the Lambdas are certainly a few notches below the HD6xx in terms of providing that resolution. Yes they sound nice and clean and clear, but they just aren't as resolving. It fucking baffles me how people can say a headphone like that is resolving...clearly we're listening to different things or have very definitions/interpretations. Hope that all makes sense

I just call everything with that same frame a Lambda out of habit.  Don't know if technically right or not.   My favorites are my modded normal bias, but i have a stock 207 and I'd say they same thing about it as well.  I'm definitely a measurements guy but between the possibly bad amp and trouble getting a seal on you rig your measurement's look pretty strange compared to Tyll's numbers on the 207 (http://www.innerfidelity.com/images/StaxSR207SB2217.pdf) and 507 (http://www.innerfidelity.com/images/StaxSR507SE11049.pdf)

It makes sense but we still don't agree.  At least I think it does.  I'd say that  "speed" and "macro-clarity" are necessary, but not sufficient conditions for "resolution".

Stock, the Lambdas do have a platicky timbre, the the HD650s definitely win there.  I can understand some people not being able to get over that in the same way I have issues with the stock HD800.  My ears get use to the plastic sound pretty fast though and I think it's other positives outweigh that negative.  My normal bias Lambdas have that completely modded away though.

I didn't really intend to start a flame war though, so just go ahead and ignore me if you want.

Makes me wonder exactly what we're each listening for because...

to my ears it the various Lambda variations I've heard do that better than the HD650s.

Bad amp? Trouble getting seal? Look pretty strange? Well, in my setup they do seem to have a large null around 4kHz for the Lambdas. But overall I don't think the measurements are too far off (specially due to seal). Could be the SRS323 I had at hand. You really feel it was that? I do not use compensation and our rigs are obviously different though. Here are the plots (note I start at 20 Hz instead of 10 Hz):

(http://www.changstar.com/index.php?action=dlattach;topic=2415.0;attach=9705;image)

               (http://www.changstar.com/index.php?action=dlattach;topic=2415.0;attach=9707;image)

I didn't have that null in with the SR009s (same measurement approach and equipment). Not the same width at least. Possible some there is a baffle reflection or perhaps an interaction with the pads. Or perhaps the cans are indeed misbehaving at that particular frequency range. Amp for the 009s was N3rdlings very own 727 (and T1 which made not a difference in the measurements actually).

(http://www.changstar.com/index.php?action=dlattach;topic=2415.0;attach=9709;image)

                     (http://www.changstar.com/index.php?action=dlattach;topic=2415.0;attach=9711;image)

Now, using the same plot parameters, here are the HD600s and HD650s on top of them:

(http://www.changstar.com/index.php?action=dlattach;topic=2415.0;attach=9713;image)

Consider that the Lambda measurements actually required a rubber band to get any decent seal (something the Omegas didn't seem to need). With hair and given the virtually zero pressure exerted by the headband, I highly doubt you are getting anywhere near the required seal to get the bass response as measured by Tyll or in my measurements. Add to that the fairly unremarkable response throughout the mids and even the treble (in Tyll's or my pretty plots) and it baffles me how these are considered revealing at all.

It's a special kind of sound IMO. Fairly artificial however. If you want to stick to electrostats for whatever reason, the Omegas are definitively a step up both to my ears and measurements wise.

Post by: Ali-Pacha on May 22, 2015, 06:14:28 AM
I don't know the HD650 very well, but there is indeed something about the detail retrieval of the HD600 Lambdas don't have : the ability to reveal some details that makes want you to turn your head because you're feeling it comes from the room you're in.
Lambdas do present this kind of details, but you won't be surprised by the way they "pop", kind of flatness in their portrayal compared to the HD600. Maybe they are eaten by the high-mids bump of the Lambdas and their concentrated (yet very airy) soundstage.

I do agree with the plasticky sound of most of stats, but maybe it depends on your reference : used to stats, you may find dynamic cans gritty / "carton-y", and used to dynamics, you sure find stats plasticky / artificial sounding / lacking body.

2 cents / YMMV / whatsoever.

I do agree with the plasticky sound of most of stats, but maybe it depends on your reference : used to stats, you may find dynamic cans gritty / "carton-y", and used to dynamics, you sure find stats plasticky / artificial sounding / lacking body.

Perhaps indeed.

Dynamics come in a wide variety of flavors though: the explosives, the ear drillers, the boring sounding, the mellow sounding, the u-shaped exciting, the neutral sounding... and indeed the gritty and cartony sounding. But not all have the exact same characteristics IMO. I don't feel the HD600s are gritty or carton-y. But I can think of other dynamic cans that are.

The stats (of which I regard the 007 highest) are less numerous, and IMO do share common characteristics. More so than dynamics.

EDIT: Please take into consideration that "objectively" all of these statements are fairly subjective.

Ultra,

that's interesting you regard the 007 as the highest. I presume you have listened to the 009 as well? Any quick comparos  between the two? Now that you mention it, the 007 I have is close to the HD 650 but methinks the latter is 'thicker", if you know what I mean.

Yup. Heard the 009 actually more often actually, but have not have the chance to do quick comparos between 007ses and 009ses. The HD6x0 in general would be thicker than either 007 or 009...  or less lean or ethereal. Depends on perspective.

That said, the question at hand is resolution/plankton/low-level-info. Now on that subject I did have a chance to listen to the Lambdas right next to the HD600s. And indeed, the HD600 had the upper hand.

Unfortunately, I've never had the chance to hear my HD600 out of a good / plankton-friendly amp, so hierarchy is not so obvious to me. But the portrayal of details I've written about in my previous post tells me there's certainly far more potential on Sennheiser side than on Stax side. I've a strong Stax bug, and it's still hard for me to spend megabucks on "regular" , but I'll buy a real dynamic amp eventually  :)p3
I do agree with you on all your other points  :)p5

Bad amp? Trouble getting seal? Look pretty strange? Well, in my setup they do seem to have a large null around 4kHz for the Lambdas. But overall I don't think the measurements are too far off (specially due to seal). Could be the SRS323 I had at hand. You really feel it was that? I do not use compensation and our rigs are obviously different though. Here are the plots (note I start at 20 Hz instead of 10 Hz)

Sorry, I should have been more specific.  The FR was pretty close except for the weird null but you're distortion numbers were way higher that Tyll's, I've seen them go lower for other 'phones you've measured so it's not you're mic, and you seemed to have an issue at higher volumes which Anax suggested was a problem with the amp.

I just read that one thread so so maybe I missed something else.

I agree with ultra about Lambdas not sealing well and thus not getting anything like that bass extension.  The newer Lambdas seem to do a lot better with bass extension, likely because of the pads.  That said, FR isn't exactly what's being argued in terms of resolution.  Like Marv said, ability to dig up low level info, though FR does have a role in that.

I have to question how much some of you have even listened to stats in a quiet environment.  I know Marv has owned some decent stats in the past and I remember a loaner of the 307(?) going around a while back.  Almost every stat has close to zero sound isolation, much less than HD6x0s.  Given that, how much can you honestly judge detail extraction in a meet environment?  I think you can get a good idea of how a headphone sounds at a meet (I'm not a "meet impressions are worthless" guy), but I think resolution is the one area that's a bit sketchy to judge at a meet.  Let's not kid ourselves about how loud meets are.

Comparing them side by side at home with a number of different amps, the difference in detail extraction is night and day.  I'm starting to wonder if maybe the technologies perform differently at various volume levels.  I know Marv, Anax, and OJ listen at like 120 dB and I listen at like 30 dB.  :P  Not sure about ultra.  Maybe at really high volumes the stats are presenting the same detail level they do at low volumes, and the dynamics don't start to reveal their max detail until you start to pump up the volume?  I think that might kinda make sense since stats are in a balanced, linear force field and dynamics are in a single sided magnetic field.

I just read that one thread so so maybe I missed something else.

The measurements that you are seeing on these particular cans on my end are from a single sweep. Lately I'm doing 8 sweeps to increase THD number resolution (removes uncorrelated noise to some extent). It is also true that the 323 amp seemed to have some issues with distortion. That said, bass distortion numbers were better with the Lambdas than the HD6x0s.

Another possible source of confusion is that Tyll displays distortion in %, while most other programs (like REW) do so in dB.

IMO low lever resolution is not solely due to distortion. It maybe a combination of many things. A notchy and not-so-smooth treble and/or mids response perhaps may bring certain details forward, at the expense of masking others.

I agree that getting resolution impressions proly require a more appropriate environment than can be afforded by meets. Fortunately, the 307s vs the 600s comparo was not done at a meet. It was a Massdrop loaner, and I was able to both hear and measure them in a relatively quiet environment.

I tend to listen at maybe 70 to 80 dB or less.

1-Speaking for myself, you we've both been to private mini-meets in quiet environments. I know myself, OJ and UB have all had the 009 in our house on extended loans before. I consider the 009 the most resolving and capable phone Stax has made to date. At this point, a 009 rig would be my choice back-up rig for less distracting and low volume listening when I need to work or have situational awareness. Not worth the cost at this point and my 800 rig is still priority but I'm finally close to complete with it. About 85% done after adding Yggy. Eventually I'll make a 009 rig unless Stax or someone else makes a better stat. Still considering the HE1000 too depending on it's affinity to modding.

2-Yes, that's correct. x100

Seriously, if I had the resources I would put together a Stax rig. But I also would want a dynamic rig as well. The best of both worlds. Nothing gives you both at this point. IMHO.

That said, FR isn't exactly what's being argued in terms of resolution.  Like Marv said, ability to dig up low level info, though FR does have a role in that.

Plankton retrieval has more to do with the quality of damping(driver) and dampening(case). That is low distortion and fast decay especially in the bass department. Slow bass/upper bass decay can hide details in other areas of the spectrum because of its stronger masking effect.
If you think about it for a while, senn's headphones are some of the few trully open designs and therefore can circumvent these kind of problems . Audiotechnicas are open too but their paper baffle doesn't seem to help bass extension and the drivers' damping isn't top notch either. Beyerdynamics and AKG are semiopen, suffering also from significant distortion(AKG) and colorations such as recessed upper-mids(beyers) and plasticky sounding resonances(AKG).
OTOH, senn's flagships lean towards the dry, transparent, professional sound. You hear more of the recording and less of the device. That's the secret of success regardless of price and personal taste. No headphone sound so that you never get bored. What a pity that the market is driven by some poser audiophiles, who value more price tag and popularity instead of achieved fidelity.

This feels to be very true for HD800. For me the big thing contributing to its 'fatigue'-ness.
Less so with HD650 ime.
Assuming our best tracks have 70dB DR we need to listen to those at 90dB minimum.

Nope, not the pads. The double-sided tape Stax uses gets leaky after a while and the driver sometimes comes off the baffle completely, so re-sealing it with something like Teflon tape fixes that.

I'll happily compare a new HD650 vs the Lambda Nova Sig off the same amp (well, with a transformer for the stats) if someone will send a pair to Australia :P The HD650 did not fare well against the SR-5 when I had it, but that was off a MF X-can V3, some 7 years ago.

It's not that clear in Marv's post that HD6x0 evolutions over the years did get rid of the Sennheiser veil('s myth ?). Maybe there are evolutions, maybe Tyll's quote explains some things :
Quote (selected)
The Sennheiser Veil and Other Issues
In a time when overly detailed headphones built by Grado, Audio Technica, and Stax pre-Omega were considered the norm among headphone enthusiasts, the HD 600 was heard as polite...too polite for ears used to the up-front treble and poor bass response of high-end cans at the time. And so the relentless damning began, gently bludgeoning the HD 600 away from it's first place position at every opportunity with the fluffy club curse: "The Sennheiser Veil."

The veil is NOT a myth. The 555, 595, and 650 definitely had a veiled signature due to overdamping. Sennheiser fixed this with the release of the 558, 598 by using thinner paper. I wrote a thread about this on Head-fi back in the day. You can easily compare phones by holding the drivers up to the light and also listening to them. It seems that Sennheiser may have taken notice too with the 650 based on recent impressions. I wouldn't trust the impressions of anyone who has a stock unmodded 555/595 and says they aren't veiled. They are the very definition of anti-clarity.

So how do the newer HD650s and HD600s compare? I'm planning on getting one to compliment my HE400s, but I can't decide which one. I've found the 650 for about $90 more than the 600, but it is really that much better? Any comparison to the HE400 would be appreciated, as well, though I've an idea on how they compare based on measurements and firsthand accounts.

For the record, my audio chain at the moment is Wyrd -> Modi -> Vali.

I believe you can find the answers you're looking for throughout this thread...but, in a nutshell as for how I hear the HD600 vs 650:

- HD650 has a bit more mid-bass. My HD650 has better distortion in the bass vs the HD600 I owned.
- HD600 has a bit of a 2-5KHz emphasis that may or may not bother you. It varies from person to person, and some may not hear it as being emphasized there whatsoever. HD650 in comparison smooths out this emphasis.
- HD650 is a bit darker and slightly more rolled up top, but, really, not by a whole lot.
- HD650 sounds a bit more refined to my ears in ways that are harder to explain, but it's subtle.

For me, it came down to the HD650 because I the HD600 sounded "hot" to me with that 2-5KHz emphasis.

My first one was bought new 3-4 years ago and my current one was bought used and of unknown provenance, but both sounded pretty much the same to me.  They both came in silver boxes and neither sounded 'veiled' to me.  They're just not artificially hot like most other headphones are.

Since I don't think I've ever actually heard a 'veiled' pair, I'm tempted to say that's where this whole 'veil' business came from in the first place.  People just didn't like that they weren't as bright as Beyers, Grados, or ATs.  Assuming there was a 'veil' which is now fixed, this is probably part of the reason why that meme still sticks around.

So, slightly different tuning aside, the 650 is "technically" the better of the two? I'm not too concerned with tuning, because from what I understand they don't seem to be all that different, and I can always adjust them a bit with EQ if need be.

IIRC, some HD650s measure with a slightly greater response above 10KHz. Couple that with a potentiall better integrated and smoother frequency response from top to bottom, it may help explain what you're hearing.

Tuning is the biggest difference that I hear. Any other refinement is going to be subtle. They're really pretty close at the end of the day with the main difference being just the upper-mid/lower-treble response.

If it turns out you prefer the HD600 sound more, you can just buy the drivers and replace the HD650 ones. You get to keep the 650 look with 600 sound.

I have an older pair with the black drivers. There was a slight veil until Solderdude was nice enough to send me a SeNNator amp/filter. Veil is gone and FR is smooth. Sub-bass is tight, when it is on the recording. Bass is excellent. Treble is nicely extended but not fatiguing. But you can not turn it up to very loud levels. The sub-bass will start to make your head rattle and the headphones FR goes off kilter.  The sound is revealing so you don't have to turn it up to enjoy low level detail.

This veil is not FR dependent. The Audeze veil is FR dependent in large part. You aren't listening for the right thing. It's like the O2 is veiled, but measures flat.

I have a very early HD650 (black driver, original pads) which sounds 'veiled' to some and 'dark' to others.
All stock... so including foam in front of the driver and the foam in the back.
Yes... used them without foam (and stocking as protector) and with the the little foamies on the rear removed.
While clarity improved the SQ didn't (for me) and reverted back to stock and used other means of 'improving' my HD650.

Also bought some spanking new pads.
These are 'firmer' and seem to be made from different type of cloth as well (feels and looks different, find the older pads more comfy so older ones stayed on.

Also had a spanking new (white/silver) HD600 with mint pads.

My findings (all measured on the exact same rig on the same day)

Old HD650 with old (original) pads and the exact same driver with new pads.

(https://diyaudioheaven.files.wordpress.com/2013/03/hd650-old-vs-new-pads.png)

It clearly shows (at least to me) the difference in FR.
Funnily enough while the original pads are 'darker' and perhaps 'veiled' to me with the newer pads they sound (and measure) a lot 'fresher' and without a 'veil'.
Same driver ... just different pads.

So is the pad material the culprit, after all they do feel and look different..
Old pads and new pads but compressed (with extra force) to the exact same thickness as the old pads are compressed (by the clamp force of the HD650 itself)

(https://diyaudioheaven.files.wordpress.com/2013/03/hd650-old-pads-vs-new-pads-compressed.png)

Yep ... sound the same and measure the same.  New pads clamping force is untolerable, old pads ... very comfy.

So how does the old HD650 with old pads compare to a HD600 with original (new) pads.

Yep, sounds about correct, the HD600 is considerable brighter and more 'flat' compared to the old HD650 (old pads)


Now the old HD650 with new pads vs new HD600

(https://diyaudioheaven.files.wordpress.com/2013/03/hd600-vs-hd650-new-pads.png)

Yes ... indeed the differences between HD650 with new pads (= close to new HD650 ?) and HD600 are pretty small.
Like Hans described just a very small difference in the lows and upper treble.


So to me the whole 'veil' thing can be attributed to FR related things.
THD and CSD is similar for HD650 old and new pads ...

If it turns out you prefer the HD600 sound more, you can just buy the drivers and replace the HD650 ones. You get to keep the 650 look with 600 sound.

Wouldn't you have issues with driver matching if you do this?  Having contacted Sennheiser regarding this issue, they sell the driver enclosure/capsules individually and don't do any driver matching.  Then again, this is Sennheiser we're talking about, who seem to have far better consistency than just about any other headphone manufacturer in the business. 

I wonder how much variance one can expect from individual drivers...its the only thing stopping me from buying two capsules straight from Sennheiser to "drop" into my HD600.

Totally disagree. Correlation is not necessarily causation. The HD800 and other phones with massive troughs of recession from 1khz-6khz don't sound veiled. Plenty of phones that have the same amount of upper mid and lower treble energy as a worn out 650 don't sound veiled. You're just equating increase in treble with more clarity. Not the same thing. The Senn 'veil' is like having a good recording with too much noise reduction applied versus no noise reduction. It's what I call 'greyness'. You can apply EQ to most veiled phones and drivers like these and the veil will still be there.

Talking about this veil is getting to be like explaining plankton to someone who hasn't heard it from an O2.

Better to compare the HD595 to 598. Pads don't mean squat here and you can physically take apart the drivers and inspect them for obvious photographic proof of differences as to why one is veiled and why one is not.

This veil is not FR dependent.

That is certainly could be true however it's not the only possible explanation.  I said I was tempted to blame the 'veil' on people not liking the FR but I didn't actually declare it to be so.  I haven't actually heard enough samples to make such a statement and the fact than Senn has changed their damping materials over the years gives weight to the 'veil' being a real phenomenon.

It's just that in a world where people can listen to most Beyers and Ultrasonnes without their ears bleeding, and in the absence of other evidence, people not liking the FR is the most parsimonious explanation of the 'veil'.

Oh I hear you. Or maybe not, as my HD800 listening might have deafened me by now.  :D ;) You can certainly 'veil' a headphone via severe FR manipulation. That may be a 'contributor' here and some other cases, but I think there is probably more to it going on with the Senns. My experience with the lower end line definitely and absolutely supports that.

On those, the main difference lay in the thickness of the paper damping over the drivers.

More heresy and all that, but am I the the only one who find these two steps from a complete ergonomic disaster?

They clamp like a medieval torture device, aren't single sided (Only 'stats have a physics based excuse for this), and add injury to insult by making the length of the y split way to short so I garrote myself when taking them off.

I wish that AKG or Beyer made anything that sounded as good that the HD650s.  Pending an audition of Anax modded HD800s they're still my favorite dynamic...

Well, relative to the Stax stuff, anything clams like a medieval torture device.

Relative to Beyer (DT990), HD6x0 clamp lots less. Relative to the AKG, I would say it's somewhat sameish. If the HD800 clamp, Anaxes HD800 lost their virginity.

Maybe I just have a wide head or something.  If I extend the sliders all the way, it will stay in place by clamp alone with the headband floating above my head like some kind of halo or antenna.

My K601 are way more comfy.  My eardrums give up after 1/2 an hour though.   :'(

The Beyers I owned were more comfy too.  I don't remember if they were that way stock or it's just because their spring steel headband is a lot quicker to fix.  My eardrums gave up on those too.

I forgot whether I had to hit the headband with a hairdryer to get it loosen up last time I owned them.  So far this time I've taken off the cups and stretched the headband across some books overnight but it tightened up again during the day.  (Insert joke here)  I'm not sure if it just needs a couple rounds of stretching or if that polymer need some heat to loosen it up permanently.

Dunno. I do have a aliens-like sort of head so maybe that's the reason it doesn't bother me that much. The HD800s Anax have sit on my head like most stats.

Interstingly, I don't think pressure on the HD6x0 is necessary. At least they don't clamp as much as some closed cans. It is what it is.

On my head at least, they clamp more than anything I've tried except maybe the Beyer DT1350.

At least the 650's clamp is fixable though, which is a big plus.  I usually mod most everything own anyway, headphone or not, so it's that big a deal to me.  Other without the DIY ethic might find it a bit daunting.

I remember freaking out when when this sort of thing was discussed in an old thread on HF.  People were aghast that it wasn't perfect for absolutely everyone right out of the box.

HD600/650 clamp for me was pretty horrible out of the box. 30 mins and I had a huge headache. I stretched both of them out over a bookshelf speaker for a day or two and also bent the exposed metal part of the headband out a bit when fully extended. Unfortunately, I accidentally stretched my HD650 out over my bookshelf speaker for longer than I meant to, and it prematurely flattened the pads a bit (though, less stiff foam, can't complain too much). :) But loosening the clamp on either headphone measurably brings up the treble a bit, which might actually be preferable on the HD650.

Not a whole lot...just a smidge, really. I can't remember if I posted all my data or just have it stored somewhere on my computer. Brings up the treble a tad and I think it might also slightly lower the mid-bass hump. Just a wee bit brighter sounding. Or I'm crazy. Decide for yourself!

So to me the whole 'veil' thing can be attributed to FR related things.
THD and CSD is similar for HD650 old and new pads ...

I agree with Anaxilus. Veil is some sort of distortion that blurs sound. It might be due to multiple reasons. Overdamping can also increase distortion.

What is interesting though is that my silk screen version bought around the end of 2010 has metallic baffle(very stiff and cold by touch), whereas the brochure(published on 03/07) inside the case states "Specially designed acoustic silk ensures precision damping over the entire frequency range". It seems to me that the marketing material remained the same for some time after the change.

FYI, mine never sounded boomy or slow regardless of amp/source. I own also DT 990 pro and I know what boominess and veil sound like, even after eq corrections. I couldn't understand what people at headfi were talking about. On the contrary, it has somewhat aggresive upper mids(3Khz-5Khz), which bring out many details and the bass is similar to that of HD 700 in terms of speed. By similar I mean not significantly different. Not in a way that can deteriorate perceived fidelity.

So, I am puzzled now that I read about leaps in performance for the most recent version compared to the "older" silk screen versions.

Using Yggy with Valhalla 2 and both hd600s/h650s. Go for it, but the WA2 may hold back the Yggy. Never heard the WA2 outside of meet conditions so I can't say for sure. You could probably do better with a Valhalla 2 though ;)

Have you tried heating the headband before?

I stretched it out again, hit it with a hair drier for about 5 minutes, let it cool down for another 30, and it's holding far better than than just stretching for half an hour would.  I'll have to give it another few days and see what happens.

Got off my ass and did it this morning. Hammer and socket is definitely the way to go for making a clean easy hole. There wasn't any glue on the foam behind my driver, so it was really easy to take out in once piece.

Completely concur with the observations in this thread: the mods improved clarity, moved the bass hump lower, and made the sound far more lively/energetic. I suspect that my HD600 isn't going to get a lot of head time after this. Highly recommended.

We need a better way to explain "resolution" to planar people...I think Marv, Anax, ultra and I all hear it but we keep running into this descriptor conundrum when trying to explain it.
...
Resolution is, as I have come to define it independently from what I hear as well as what I glean from others, the ability to portray information on the recording. The ability to render the picture/frame in its entirety if we want to use the video analogy. It's not a big leap to extend that definition to include both microdetail (plankton, inner-whatever, etc) and spatial information (ambient cues, precise imaging, etc.)
Just finally reading through this thread, and this ^^^ is EXACTLY how I feel comparing the ability of the 650's vs the LCD-3F's. Thank you. I have never heard a planar that offers the resolution I hear from the 650's/800's. I would really enjoy if I could, but I haven't. The mistake I've made multiple times is thinking that more expensive headphones would naturally offer better resolution. Aha, fool me, you can't get fooled again!

It sounds crazy to the uninitiated because the planar drive mechanism is better on paper and a lot of people seem to expect cool-looking, exotic tech and big price tags to go hand-in-hand with superior performance. But the proof is in the pudding. Dynamics tend to be more resolving for whatever reason. I'm not a big believer in Marv's crazy idea that the tension kills resolution, but there's gotta be some reason they have that sound.

I appreciate the bass/impact/speed of some planars, but I hear what I hear, and value the dynamic drivers resolution above all else. Without that resolution, it's a deal-breaker for me, and I'm wondering if I'm in the minority. For me, once you hear it, you always expect it. And that is why the Yggy has ruined other DACs for me. :)p14

It sounds crazy to the uninitiated because the planar drive mechanism is better on paper and a lot of people seem to expect cool-looking, exotic tech and big price tags to go hand-in-hand with superior performance. But the proof is in the pudding. Dynamics tend to be more resolving for whatever reason. I'm not a big believer in Marv's crazy idea that the tension kills resolution, but there's gotta be some reason they have that sound.

I may be incorrect, but from what I understand, the planar membrane is driven from traces outward, and there is a lot of trace area compared to the voice coil. For planars, this could account for the bass (less break up, since more membrane area is directly moved) and clarity (similar reasons, and frequencies are evolved from the large area of the traces). Speed is arguable. The voice coil takes up less area in the membrane proportionally than a planar driver, so the sound is evolved only from a ring, which also simulates a point source of sound. So although the sound may be less clear in the sense of say being from many areas in the driver and reinforcing itself a la chorus (planar), you get the clarity and resolution of one area/ring of the driver a la a solo (voice coil), and thus better hear the timbre, or with headphones, resolution.

So are planars like anti-aliased images vs true resolution of voice coils (more polygons/pixels)?

CAL, MA100, R10.

CALs have "resolution"?  I have a pair, and I think they have a nice tonality and timbre, but I don't feel like they resolve much detail.  Maybe this is where the definition of "resolution" is the key - in this case maybe the CALs don't have any algae or jellyfish or whatever you guys call it, but have the other cues.

Honest question for you.  What, if any, dynamics do this besides Senns?  It's pretty much always the HD600/650/800 mentioned around here.

The Senns do seem to be the most resolving dynamic headphones that I've heard. Other ones...the Fostex TH900 is pretty resolving despite its effed up tonal balance. I like the DT880 if you can match it with the right tubes...that's a good dynamic sound. If we want to talk cheapies, I think a cheap dynamic like the Tascam TH02 is pretty resolving for $30. I'd prefer a modded TH02 to a modded T50rp.

When you start looking at dynamic woofers it's pretty amazing how resolving they can be. Ask Anax who just plugged in a pair of cheap aluminum cone and silk dome. More clear and lively than any planar headphone. And we're talking $15 4.5" woofers...the catch is they use massive Chinese magnets that are bigger than the basket  :-0

Plug into Yggy/Studio. Play Eagles Hotel CA. Compare ability to hear string decay at intro with other headphones. Never said these cans weren't all distorted and shit, but it is possible to hear past this. I wanted to offer an example at low cost - they are pretty good at "plankton" specifically at that price point, but have other serious issues because of the small size of the driver. Sennheisers (HD800/650/600) are better of course. In hindsight I should have just said nothing about CAL or MA100, because this seems to cause confusion. Also resolution does not necessarily = detail.

Yggy changes everything as well as what else you have in the chain. It's no accident ohG didn't hear as much difference between his AGD and Yggy with the HE-6 with preamp with power amp.

I'd agree with you about the resolving power on the T50RP.  You can't really get over the distortion in the midrange with any mod.  Once you mod them though you can get rid of of their other sins of commission so they end up doing a good job of "getting out of the way" which is my primary criteria for a headphone.

I think the DT880 is probably Beyer's best headphone.  It's got a metallic timbre that I don't really like but it's not as bad as most of the rest of their 'phones.

Overall I think it's more the implementation of a given technology than just that's something's a dynamic, or a 'stat, or a planar magnetic.

I really like most of the Stax that I've heard and the ESP950 as well, but the Kingsounds don't play in the same league.  I really liked the LCD-2r1 I heard but didn't like any of the new fazors as much.  The only HiFiMan I really liked was the HEK with the HE6 as a runner up due to sharpness in treble.  (Haven't heard the 400S yet though...)  IMO Sennheiser is pretty much the king of dynamics and the HD800 is the pinnacle of dynamic headphones.  Actually I think I've liked every Senn I've ever heard except for the HD700.

That's true, HEK and some vintage planars are more resolving than most other isodynamics of today. In general, I do feel that there is sort of an "anti-aliasing" effect, for better or more worse, with most of today's planars.

With the tweaks, the HD650 sounds faster, crisper, more lively, less over damped. I would not attempt these tweaks on the HD600 though. Overall, maybe a few db too much mid-bass, but everything else sounds just right.

I removed the rear foam and heard the mid-bass as a bit too boomy/muddy, similar to what I hear with a higher Zout source but less pleasant (dual mono Buffalo IIs directly into a Lundahl amorphous core OT).  I wonder if there is a subjective difference between decreasing the acoustic damping (the mod) v decreased electrical damping (higher Zout).  I also wonder if the "quarter mod" would re-store the subjective balance (I replaced the foam and didn't proceed with this).  Did the CSD change with the mods (I realize it might not have been measured pre- and post mods)?

Post by: graean on June 17, 2015, 05:06:06 AM
CSD should show longer decay, since there the air is now more compliant and does not as strongly resist the driver's excursion and return to the center position. With treble, this is good, since the treble wasn't all too present stock. I assume mids sound more wet/full/lively (like a very brief echo/resonance, much like the one you hear in your chest when singing). But the bass is becomes slower than it already is (although now at a lower dB). I think that this mod is a matter of exchanging better FR and impulse response for worse CSD. FR is becomes flatter because the back foam is a semi closed chamber that reinforces bass at a certain frequency and attenuates but causes some ridges in treble (since the foam reflects some treble back). Keeping front damping without the quarter mod also contributes to bass resonance and treble attenuation (and spiking).

I see how you describe the headphones as boomy; the modded HD650's articulation is faster but less controlled.

Post by: Bill Brown on June 17, 2015, 09:39:49 PM
Interesting re. your observations/thoughts about CSD, similar to what I was thinking.

As to FR, I had been thinking the rear foam damped the combined driver/rear chamber (more like a short pipe, I guess) resonance.

Perhaps it is the combination of the two mods that is required to restore subjective balance.

I have known my HD650 for many years now.
Had (brief) love affairs with many other headphones but always returned home to the HD650.
Maybe because I can trust it.
Maybe because I feel I can easily get the best out of it without having to alter it physically.
I take it the way it is, just feed it with a different diet as it were.
Had to fill up the two cushions on the top once and now its firm again.
Otherwise the HD650 still looks and feels great and love every song it sang for me.
Still very happy with this HD650 and have the feeling it will never leave me.... God knows I tried a few times though.
What more can I say .... not a FOTM for me, not even a FOTY or FOTD

Chain yourself to the 650's and then put on a blindfold.
If Sennheiser comes up with yet another revision of the HD650's I'll buy again (although I have the latest one atm)!
^that is unless they turn the 650's into crap like momentums, urbanites, HD630VBs or something (highly unlikely but you never know by looking at the last few headphones/in-ears they made).

My first pair were the updated drivers, but sound a lot darker compared to the ones I bought last fall. The newer ones seem to offer a more linear response; instead of having an overall emphasis of dark, rich mids, the treble of the new ones sounds much more resolved.

It took a month or two, but I now much prefer the newer pair. Not sure if it is simply pad wear, or the clamp that is causing the difference. It is quite a contrast between my pairs though. I also found the clamp naturally eases, to the point that after three months, I'm glad I didn't fk with the band to lessen it. The old ones clamp far less.

Still loving my HD650's, especially with the mod purr1n posted. After listening to the HD800's though, I am in love with the hd800's, too bad they are only a loaner pair, but the HD800's are the best I have ever heard. But the mod that purr1n posted, really makes the HD650's sound better IMO, and for the price, they are an unbelievable value, and if they are underated for their price point, there is a problem IMO.

That combo was my endgame for a while, but I got frustrated that I had to swap depending on genre.  Ended up selling off the HD800, living with the HD650 until a new flagship came out that could give me all the wonderful technicalities of the HD800, with just a little bit more warmth and smoothness like the HD650.  Now that I have a better source (Pulse Xfi + LPS) to pair with my Bottlehead S.E.X. I almost don't miss the HD800's.  Almost.

Nah, the 600 and 650 will never be turned into crap. Look at Porsche. Purists cried foul when the Cayenne SUV was introduced, saying it would ruin the 911 in the process. 13 years later, the 911 is still the 911, and that's not going to change no matter how many suburban mommy-wagons they sell. Sennheiser is following the money right now. It doesn't mean they are completely abandoning the reputation they have built up amongst audiophiles and music lovers.

I hope so. I heard they will release a high-end open back not too far in the future. I hope they will come up with another great like the 650 or the 800. But then heck, the 800 is still so hard to get the best out of.

Speaking of which, I saw a Korean news report a few months ago where the person plugs the HD800 into his phone and listens and then compares it to some craptistic $4 headphone and ends up with a conclusion that the sound is about the same, if not worse. HD800 sounds harsh and is a bad deal according to him because it's $2300 (which is wrong). It's actually around $1100 in Korea.

Funnier was the time when I saw someone plug the HD800 into his iPhone then wear the HD800 backwards. Oh the humanity. :p

As a warning: For anyone who feels the need to pop out the HD6xx driver be extra careful. I believe I just ruined one side my HD600 for the worse a la Tyll:

http://www.youtube.com/watch?v=mBpic9jbjzs&t=8m20s (http://www.youtube.com/watch?v=mBpic9jbjzs&t=8m20s)

The dome itself is in tact but there are some crinkles in the surround plastic that I can't get out. I am going to order the HD650 drivers and see what kind of results I get. As I've mentioned before, I've always felt that the HD650 was a more refined sound despite the darker tuning, so it'd be interesting to see how much of that is from the driver vs the construction. Will post comparative measurements.

Sorry for another post, but this is very interesting to me.

For the past month, I was privileged enough to finally be able to get a loaner pair of HD800's to check out. Those were the only headphones I have listened to for the past month until I shipped them back out yesterday. So I got out my HD650's after not listening to them for a month. Immediately I noticed how much darker they are (Marv told me a while back that the HD650's were a darker headphone, I kinda understood what he meant, but now I really understand what he meant). This is not a bad thing, in fact it is a good thing for me personally. I learned that perhaps I do not actually prefer a darker headphone - but this is where I learned a lot about the HD650 and how much more I appreciate them. I lowered the bass frequencies on my EQ (I use iZotope OZone 5 and 6 plug-in for EQ, one or the other) and with the mod Marv posted for the HD650's a while back that I did to mine, I realized I can get pretty darn close to the HD800 sound signature when EQ'd properly. Of course, the HD650's do not possess the clarity of the HD800's IMO, but for the price of the HD650's, they are just so much more amazing to me now and I have gained a deeper appreciation of what a great headphone they are for their price-point.

For me, I still prefer the HD800's, but the HD650's are a very close second, and if they were ever damaged, I would get another pair if I could not get a pair of HD800's.

I think some people would prefer the HD650 over the HD800, depends on the listener, but that just goes to show how great a pair of headphones the HD650's are. I definitely have a new appreciation for how great these really are.

I covered the HD650's back side with small cut bits of microfiber cloth (costco, blue) adhered by elmer all purpose washable school gluestick, putting cloth on gluestick then on headphone. I covered the bare plastic, except the circular part of the driver itself, and I put bits of free nonglued cloth into the slots to cover the steel damping mesh. The glue is washable, easily removable, and adheres weakly.

It's more listenable. The treble is smoother, mids are more textured and clear, and the bass isn't so bloated (less bass bump, less roll off, less distortion) and hits a little harder, faster. A little less claustrophobic. I have some other mods in place, though. Can anyone corroborate?

I listened to them on two systems:
  CD transport -> Woo Audio WA7d Fireflies Wa7tp
  computer -> a stack that included an Auralic Aries and Taurus, and I'm not sure what else

I liked the sound much better on the Woo system; the Auralic stuff sounded overly polite to me.

Now at home, I'm using MacBook Air -> Wryd -> GO450 -> Vali -> HD800. It sounds a lot like the Woo system, but I think I'm getting better resolution.

Love the thread title. I'm toying with the idea of inflicting the rear foam mod to see if it really does reduce the mid-bass. That's about the only 'fault' I hear in the 650's. I'm also waiting for Solderdude's filter & don't want to pull the foam and so make the filter redundant before I even get one.

I'm currently achieving the best sound I've ever personally heard with headphones.

JRiver MC19 > ODAC > Project Ember MkII with 1945 General Electric 6SN7GT VT-231 > Sennheiser HD 650

Bliss!

Removing the rear foam will bring out the mid-bass. Adding damping behind the driver will help lower it, and bring up the treble a bit, at the expense of making them sound even further overdamped to the point where they might develop a sort of high-pitched grain or sense of strain to them.

Perhaps removing the foam directly behind the driver but adding foam within the cups could be a way to dial in the bass without overdamping them as much. I haven't tried it.

The foam in front of the driver also plays a role in the amount of mid-bass. Remove it entirely, and you lose a lot of bass...and get some nasty treble effects. If you cut a larger hole in the front foam than the mod suggests, so you can see more of the surrounding silver material around the driver, you may get some positive benefits to your ears.

Personally, I like the mod as-is, even with the extra mid-bass. Pair them with an amp that doesn't add too much thickness to the sound, and it balances itself out nicely. The modded HD650 pairs very nicely with the Valhalla 2 and NOS Telefunken tubes. Val2 isn't particularly thick or bassy sounding, nor are those Tele tubes. Works great with the modded HD650.

Could also try some enclosure/frame damping to see if that reigns in the bass.

So removing the rear foam will increase the mid-bass? Well, that's that out the window then.

I've been playing around with a parametric EQ to try to even out the mid-bass but it's not too easy. I have managed it to a certain extent though & I like what I hear. Bodes well for Garage 1217's filter when it arrives.

Might be amp dependent, but I did not experience increase with mid-bass upon removing all three layers (they are squished together) of the foam in the back.

Another possibility is the HD600 if you want to tame the HD650's midbass.

I agonised long & hard between the 600 & 650 but eventually went with the 650 because sometimes that extra warmth is nice. It's also easier to remove something with EQ than it is to add, up to a point. I'm really happy with the 650's & anything now is just massaging them to where I want them. My journey with valves has been with the same goal.

You should still consider removing some of the front foam or perhaps adding some light damping in the cups.

What phones do you guys consider definitely better than the HD650?  I've tried or owned many phones $2000 & under, but I really haven't found anything I like as well or better yet. I'd like to find a great classical headphone, and the 650 is perhaps a little to dark to be ideal for classical, although it's my favorite for everything else. I usually find the HD800 to be a little to bright to sound realistic.

Hmmm maybe the 800's modded or driven by tubes that are gently rolling off the treble? I'm a huge fan of the 650's myself, and can't really stand many other headphones. I also find the 800's fatiguing, but I have sensitivity to treble (hyperacusis). I adore the 800's, I just wish I could listen to them forever like the 650's. My ears literally get pained. Glad you also enjoy the 650's... they're beautiful.

In terms of absolute techinical performance, modded HD800. STAX and Higher end HiFiMan might fill the bill. Might.

If you factor in gear matching, price-to-performance, scaling with gear, nothing beats HD6X0. Though HD6X0 aren't my favourite.

Yep.. the most up to date 650's have 'silver screens' round the driver.. this is easily seen through the grills.  The most recent Senn update happened quite a few years back.. so the chances of you getting an 'older' HD650 are far less than getting a newer one.

Good luck!

I covered the HD650's back side with small cut bits of microfiber cloth (costco, blue) adhered by elmer all purpose washable school gluestick, putting cloth on gluestick then on headphone. I covered the bare plastic, except the circular part of the driver itself, and I put bits of free nonglued cloth into the slots to cover the steel damping mesh. The glue is washable, easily removable, and adheres weakly.

It's more listenable. The treble is smoother, mids are more textured and clear, and the bass isn't so bloated (less bass bump, less roll off, less distortion) and hits a little harder, faster. A little less claustrophobic. I have some other mods in place, though. Can anyone corroborate?




Pics and or list of other mods, please.

Thin Creatology foam works better. As few gaps as possible. As exact as possible. Using tissue paper and markering it out and glueing it on foam to cut it out works for certain parts. Pads massaged, wrung between fingers to better conform to ear. Foam insert too. Seems to increase linearity and extension. Wear gloves to avoid massaging in hand oil. Sharp scissors. I lined all the black plastic and the silver damping mesh. Foam is softened a bit by crumpling and crumpling, to make it pliable. That should make it a little more porous. Felt/cloth caused a 5k spike, damping everything except the worst resonance. I scrubbed the backside of the earpad with a stainless steel brush, for better diffusion of sound. Applicable to all parts except where the sound is travelling directly out of the driver. Polish with a microfiber cloth, etc, fine, reflective wax/surfactant. I pushed the back damping foam so it curved and exposed the magnet a bit. There is still damping to restrict the air, but the reelection from the foam happens later, so treble is a bit more linear and extended, at expense of worse slightly worse decay, but better FR and impulse.

When I added foam or microfiber and didn't cover hard surface, simply taking up space and obstructing diffusion and causing earlier refelctions---I caused earlier reflections. Resonance at couple certain frequencies. It is higher resolution--as per faster decay every where else. But FR sucks real bad. I tried free foam, less dense, and that helped decay, but hurt FR by roll off at both ends.

This of course, is tentative, what ever works for you.

Covering the plastic surfaces of the inside of the grill seems to work, but I need to test that again. I tried puncturing and abrading the surface of the foam to increase surface area, but I need a way for it to be controlled and repeatable. I used a screwdriver and steel brush. The steel mesh itself is removable, if you push right close to the edge, and you can fit foam/putty in the crevice, before/after you glue it back. Stock glue is like hot glue-ish. Thickish viscous drops.

I brushed the steel surface on the inside. I put some foam in those cylindical holes on the grill cover and in the headphone backside.

Putting foam in the front of the headphone, where the plastic is--that's tentative still. I tried it a couple times, but I want to focus on backwave damping first, where the cavity volume is far bigger so I will induce less resonance by obstructing the sound waves.
I did brush it. I covered the driver opening with tape first, to protect it. If you make the back side of the headphone fairly hermetic, as with the foam, you rish crumpling the membrane from the suction when removing it. It's mildy harmful, but I didn't notice any terrible effects. Still sounds similar. Might sound different. But burn in and the other mods and mod removal make it hard to strongly causate.

I tried putting foam underneath and inside the lower part of the grayish headphone bolster thing. It helps high treble but is probably a tertiary thing for you to try. Also lining the mesh on the front of the headhpone, making sure not to obstruct the driver that is covered by the mesh. So theres the area of the driver opening and then there is actually twice the radius of membrane surface behind the mesh, obscured. Weird--in that it contradicts our popular notion "don't obstruct the driver". Senn apparently needs it. Bass propagation surface.

So, principles:

1. cover hard surfaces with more compliant material to absorb spurious waves that reflect and add non-signal noise to the driver. You need hard surfaces. Bass. But you need some reservoir to absorb extra energy that doesn't float into free space. And even a free space driver--you've heard them (take out the driver and hear it in free space, though your own risk cause the wires are stupid (not really stupid though) small) have little bass and mids sound smothered. Kinda like that popular Koss. Linearish. But decay still sucks.
2. make no irreversible mods
3. keep cavity volume as high as possible
4. make most hard surfaces irregular to scatter sound
5. mod one side first to experiment and compare with stock
6. do both sides at the same time, to ensure the same sonic result in both sides
7. felt, cloth, more porous foam kills bass, harder less compliant is conducive to bass
8. "bass" "mids" "treble" are not necessarily exclusive. Bass notes pop in with treble and have timbre in mids. Linearizing and helping the decay of the latter can help you hear the former. Treble notes can start in mids and evolve all the way up. Cymbals are kinda like white noise and need linearity to sound full and good decay/attack to not sound like noise or mush. And mids by god, are each individual instrument's tones across the spectrum, and would really like you to have everything in FR
9. check with sine sweeps and a variety of songs. I use retro video game songs because of their simplified, synthetic timbre and soundstage allows to more easily pick out sounds and also treble peaks/broad humps (megaman wily stage, Katamari Damacy etc). Youngblood brass band for precussion and timbre and soundstage complexity and instrument placement. Depth. Decay. I used to use daft punk, too. But it was kinda annoying in the repetition and musical structure--but early on that repetition was what I need to pinpoint sonic characteristics. Then the good stuff, well mastered stuff. But only after it passes the previous tests.
10. tonality and technicality together will sound sweet and full and impactful and you won't need to strain to hear every instrument. You'll just hear it. On the way to getting there, I felt the mids popped out, but the treble was in the background--mids spike. Or the mids and treble both popped out but the bass was lacking--mid and treble broad hump. Or that the bass was really strong and mids were full but I got a headache--bass bump w/o extension and lower distortion. Or that it was airy but not really--non linear treble, a dip in the middle. Or that everything sounded so alive but lacked full body--last couple octaves of treble linear but high mids spiked or sucked out.
11. tools were shozaburo white steel scissors, which are high-quality fabric shears, and husky precision screwdriver set to place the foam, when fingers get glue and refuse to release. Used 3m ones and couldn't cut to the size I needed.
12. you'll make a mess and smell of plastic and organic compounds and tarish stuff, so take the audio headaches, time, frustration, and exclusion from the rest of you life accordingly
13. done well, you'll eventually realize what Anax says when he values technicalities and micro-resolution more than FR. And it'll jive with what you've done trying different tonalities to get the info better revealed by technicalities. Presence of an instrument is being able to hear finer and greater range of delineations in pitch and dynamics.
14. small little sub milimeter pieces of foam and covering matter. I hope you'll be able to be able to hear their differences in helping the acoustics.
15. dynamics, when damped better and better, lose grain and reveal resolution deeper than planar or stat. Planar and stat have a choral effect with sounds. Its a matter of number of singers, more # with stat.
16. when you smile listening to music, when it gives you no earaches, when you can take off the headphones and not feel real life audio now sounds off or weird, when you can turn it up, when each recording has totally different soundstages and mastering and you can hear it, when headphones allow you to get by with 2-3 hours less sleep a night because the music is good enough to calm you down that much, you're done. I'm not there yet. Tried, got there with another headphone (a planar), messed it up, and now I'm at a platform with greater potential and far better comfort.
17. softer earpads and headpad better fit it to the head. comfort and sound increase.

It might be better to wait for the opinions of others since my experience of high-end headphones is rather limited. I can only say that the only weakness I've experienced with the 650's is in their reproduction of large scale classical music because the soundstage just isn't big enough. For everything else though - and especially considering the price - these are my end-game headphones.

It raises the low-bass as well and shifts the mid-bass hump from around 100Hz to 80Hz. Either way, I'd encourage some form of modding. The HD650 in stock form sounds a bit overdamped despite its mid-bass hump.

I've managed to effectively remove the mid-bass hump with JRMC's built-in parametric EQ. It's not perfect but it's close. What I can't do with EQ is add sub-bass. It's maybe not even possible. It's much easier to remove things than it is to add them.

Thanks for the link! Hopefully the deal is legit - their parent company is listed as an authorized Sen dealer. Had the 650' for a stint earlier this year but for some reason gave it up in hope of newer and better. Got Fidelio X2 on an amazon deal and while it is a great phone out of the phone, it does not have Senns wow factor on the vocals and sometimes the treble is grating.

I bit the bullet and took the foam from behind the drivers off last night.  I was expecting a more drastic change but it was pretty subtle.  Still sounds like the 650, which is great, but with a tad more openness and clarity.  Nice.

How has it affected the mid-bass, if at all? I'd like to reduce the hump but I'm nervous about non-reversible mods.

Removing damping behind the driver is only going to bring that hump up. These mods are reversible if you are careful not to ruin the material when pulling it out, though it will take some care and patience to get it back in properly. You can add further damping behind the driver or in the cups to reduce the hump, but that might make them sound too overdamped or even off in the treble (glare, grain, etc.).

Removing damping in front of and around the driver, front side, will reduce that hump, and possible some of the low bass, and may also make the treble weird.

A year or two ago, I took the plunge into headphone addiction. I had various lower end headphones and some Sennheiser HD555s. Those got the most use, and I didn't believe I needed an amp. After all, I didn't need more volume than I was getting.

But I found Head-Fi. I bought a PA2V2 amp and my eyes were opened. My wallet opened even farther.

I dove in and got the Sennheiser HD598 and tried/returned a dozen headphones, with my favorite returned can being the Beyerdynamic DT880. They were a little bright for me and the earpads didn't quite fit my annoyingly tall ears.

Finally, I saw the price on the Sennheiser HD650 "crash" down to $400 when it was usually closer to $500. I bought them.

I absolutely loved what I heard. I couldn't get over how good they sounded. I used them with the PA2V2 and no DAC to speak of.

Then they sat in their box. They clamped so hard that they got uncomfortable, and they didn't sound better enough than the 598s to dig in the box every night to get them out.

I picked up a Creative X-Fi Titanium HD sound card because I'm a gamer and thought I'd try that out with my 650s. They sounded even better from that sound card than the PA2V2.

I then decided I'd use the expensive monsters and decided to bend them out until they weren't super clampy. It took a certain amount of bravery to do that, but I eventually got them to the perfect tightness. Then I bought an O2 amp and fed it from the RCAs of my X-Fi. The sound got better again.

I'm several more amps deep and many more headphones along now, but I'm still amazed at the sound of the HD650. I live in closed, semi-closed, and IEM land all week at work. When I get these open headphones on each weekend, like I'm doing right now, it's like breathing in the crisp, fresh fall air first thing in the morning.

Now I'm diving even deeper into the danger zone and looking for a tube amp. My wife is gonna kill me.

Just picked these up after being inspired by this thread and realizing over time how fatiguing my HE560's were. Initially, what impresses me most is the expressiveness of voices. I've been listening a lot to the new Alabama Shakes record, and the quality of Brittany Howard's voice is markedly more nuanced on the HD650 than what I've experienced on other systems (ortho headphones, speakers). Also, no fatigue after long listening sessions. So yeah, wish I had started here and saved a lot of money. Want to thank those on the thread who have sung the HD650's praises. I think I ignored it for all of these years because I wrongly assumed it was dated.

I use the HD650 and HD600 a lot more than I do the HD800.  Easier to just relax and get into the music. HD800 causes me to focus too much on picking everything apart instead of just enjoying the music.

I've heard unmodded HD800s and loathed them. It was the difference between enjoying a beer with friends (HD650) and judging beer from homebrewers on up to professionals (HD800). There was no joy there for me.

That said, I've really wanted to hear modded HD800s and hope to someday. I know marvey has/had both and could certainly articulate what he likes about each.

I own all 3. I use the 6x0 series for enjoyment and the HD 800 is used for critical listening initially. Once I like the source, believe me, the HD 800 (with the Anax 2.0 mod) makes me immersed in the music without the need to nitpick.

Put on the Stax SRS-2170 for a while today, first listen as I just picked it up... I was thinking, "Mm, yes, there is that Stax sound... and these are fairly resolving... they sound decent!" Initial impression is they are less warm than the 650's, a touch on the lean side, but resolving nonetheless. Decent decay and worth giving a shot as keepers. A few tracks sounded very nice.

Swapped back to the 650's with the Zana Deux, and I'm as astounded as I was the first time I heard this combo. They sound clean, full, refined, detailed... just entirely enjoyable. I am waiting on the MB Gungnir to feed this, and I will convince myself to just submit and stop chasing. Maybe.

I'd also like to compare the new ZD to the original that I have. I can't imagine the 650's sounding any better.

My pair from the Buysonic deal arrived yesterday.  First impression.... damn these pads reek!   p:0   Guess they need to do a little off gassing or whatever lol

Anyhow, they are burning in right but even in the first few hours it's obvious why these things are the price/performance benchmark against which everything gets compared.  Completely competent everywhere with no obvious faults.

I need to get a balanced cable so I can get the best out of them with Ragnarok.  Anyone see anything wrong with this one?

My buysonic Senn 650 arrived too - supper dupper thanks for the tip on the deal Pfillion! While the Mj2 is all the rage these days, I am happy to have received the Vali - cracked down and got it now to go with the 650' instead of waiting for the pumped up Vali uber that the faithful are praying and waiting for. (Jason, our Shiit father, hear our prayers!). Using this out of a Mac desktop, Mostly ALACS => Fidelia => Wyrd => Modi 1.0.

Love the 650 combo with vocal/opera where it seems to edge my other headphones (humble Fidelio X2 and HD 558). The difference is small but huge - strange, the extra drop of honey on the vocals makes the magic happen. For other types of music X2 seems to take the edge - big symphonic stuff, neotango, 60's rock. Surprisingly to my uneducated ears the HD 558 hold their own very well and are not too far behind (dumb dumb n00b! - but I guess blessed the weak of ears as this is the way to financial solvency in this rabitthole).

Comfort wise I think HD 558>/= HD 650 >> Fidelio X2, go figure. Fidelio X2 is heavier and way to big with a lax headband. While I have a largish skull (just measured for kiks at 59 cm frontal to occipital perimeter and mostly have to buy XL head gears) this is saggy and requires readjustment. Makes me feel like

(https://images.duckduckgo.com/iu/?u=http%3A%2F%2Fstatic.guim.co.uk%2Fsys-images%2FGuardian%2FPix%2Fpictures%2F2011%2F5%2F9%2F1304960268526%2FYoung-men-in-sagging-trou-007.jpg&f=1)

I guess after the X1 was reported to be too tight in some corners, Phillips decided to make X2 fit all the buffalo heads out there and block this type of moaning.

To end the tangent diatribe and return to the 650', I am glad I got them and happily for my headphone hobby career, hope they will be my best game, like ever.  These days with more headphones in the house I realized I am actually not a huge fan of headphone listening - feels too isolating, if anything prefer listening to so-so audio engine speakers and be able to roam around and share the music with the rest of the tribe if given the choice. The 650 may get a place in the future family museum next to my grandfather's HD 414 that have been resident in the house since the late '70 and still work without coughing although nobody listens to them now. To go back and qualify my wows for headphone abstention, maybe, if they ever release the lost HD 658 - with improved comfort, angled drivers etc, maybe, maybe... or maybe they will just have the new ear cups that can be swapped in the old frame, Lego style.

I am waiting for the LH labs pulse infinity - yeah, yeah, I know not optimal compared to GMB/MJ2, but for less than a kilo-buck at initial campaign offering, I think I would be difficult to do better for this type of money. Besides I already payed for it, so not much choice at all. The whole kaboozle is balanced and will like to try this fad too with the 650, hell it's there, so why not? The ebay cable seems interesting. As an alternative, does anybody have any experience with Charleston Cable Company?- their cables got an ecstatic nod at Headphonia and appear to be reasonably priced, but I am not even sure they are balanced or just have a 4 pin connector:

Thanks for the advices! While I find the 650 are squeezing my brains a tad, I think it's preferable to sagging and they are quite comfy, better than X2 and close to the 558, so no issues there, they will only get better :)p5

I am curious about the Charleston cables, if any pirates have used, but is not urgent. Waiting for the LH Infinity delivery goes at the glacial pace of waiting for Godot. I literally started to get some white hair since I subscribed to their campaign - to play a broken record: what a diabolical and addictive marketing strategy, going up the ladder and getting to pay a price I would have not agreed to presented as a whole, but was broken down in small tasty bits and made palatable. Had I known about the waiting saga, would not have gotten it even with the tasty bits, but with a retrospectoscope, it's always 20/20. I find the Shiity approach of delivering before talking about products preferable, but, hei! it's a free country, so nothing to object. If it happens during my lifetime, will be interesting to see how it sounds, when it's finally arriving. The lack of chatter, and the very few and bipolar reviews, somewhat subservient but with double entendre conclusions are not very encouraging. It is still likely to be an improvement to my current modi.

Order a stock cable for $24, cut the 1/4" TRS plug (leave a reasonable amount on the plug and make an adapter if you want), then solder a 4 pin Male XLR plug to it (another $5 for a Gold plated Neutrik).

The wires on the stock cable are coated with enamel, but can just be burned off with a lighter. Instruction are somewhere in this thread... edit, found it post 144 and 145

I'd do it, but I am running around crazy these days. Changstar is actually another job for me. That means I have four jobs.

Anyways, you want this part for the 4-pin: Neutrik NC4MXX-B

If you want to make a female 4-pin to stereo phono adapter, this part: NC4FX-B (and the stereo male phono of course - just reuse the stock HD650 piece)

Got hold of an almost new HD650 in immaculate condition and have been listening, modding and experimenting with it over the last days. I have also been able to compare it with my modded HD600 and I have to say that the 650s provide a tad more tonal coherency over the frequency spectrum. I concur with those who have been stating that they are a little more resolving than the 600s. CSDs are also a little cleaner, and - what measurements do not show - the bass is better integrated with the rest.
I am currently running these with slightly worn thus shallower pads and some damping, which takes down the midbass hump that I personally do not appreciate. They are nicely warm sounding, still providing enough detail without any hint of sibilance, edge or grain. I must say these seem to be the best investment into audio I have made so far.
Fourth pic is a reference as to how the stock hd650s measure on my rig.

Post by: Luckbad on August 25, 2015, 03:24:26 PM
Interesting mods. Pulls 2-3kHz up a bit but also seems to cause more mid-bleed from the bass. I would expect that frequency response to sound more wooly than stock, but maybe the upper mids that it pulls up make that inaudible.

Stock foam is kept in place behind the driver, the front foam has been removed, BUT a ring of foam is kept UNDER the pad lid, which connects the pad to the baffle. There are 4 holes in the baffle. You can keep the bass response by covering the holes with foam (like with the stock foam in place)  or decrease the bass by removing the foam.

The contenders are LCD-3F ($1950 new, ~$1500 used), HD650 ($300 new if you wait for a sale).  HD650 was driven single ended from Ragnarok and is brand new with approximately 50 hours of burn in.  Due to amp topology a balanced cable will improve it but I am highly doubtful my impressions would shift dramatically.  LCD-3F was driven balanced from Ragnarok and was manufactured Nov 2014.

I prefer a slightly dark signature as I find myself sensitive to harsh mids or treble.  I also primarily listen to latin music which contains a ton of mid and treble energy from brass and percussion instruments and becomes fatiguing (almost painful) VERY fast if there are issues in the upper mids/treble.

Overall FR curve as I hear it:  (I have not measured either headphone; I should request the FR chart from Audeze, will update when I do)
HD650: Neutral mids/treble, minor midbass hump
LCD-3F: Neutral bass, recessed mids, slightly rolled treble

Quality of Bass:
LCD-3F > HD650
The LCD-3F is clean and punchy like good bass should be.  Only the physical sensation is missing but you cant get that from a headphone.  I feel the LCD3 does a very good job here.  The HD650 is a bit flabby and uncontrolled.  It's not bad but obviously inferior to the LCD3.

Quality of Mids: HD650 = LCD-3F
I feel they are about equal. The LCD3 is recessed however I don't hear any issues and the resolution/plankton is very good for both headphones.  The HD650 is more appropriate for critical listening however the more forgiving/colored nature of the LCD-3F makes it a more enjoyable listen for poor masters.

Quality of Treble:  HD650 > LCD-3F
No contest, HD650 wins.  I hear what I think is a minor hotspot somewhere around 8K on the HD650 but it does not grate and overall the HD650 is still significantly superior to the rolled LCD-3F in the treble region.

Tonality:
HD650 > LCD-3F
Small victory for the HD650. LCD-3F sounds a bit "electronic" or "robotic", HD650 sounds quite natural.

Soundstage and Imaging:
HD650 > LCD-3F
HD650 has wider soundstage and slightly better imaging.  Unsurprisingly they both get absolutely destroyed by my studio monitors.


Overall:
I am going to wait a few months before coming to a final conclusion but my initial impression is that with my equipment the HD650 is the better headphone overall (and for what I want to do which is mastering type work) although the LCD-3F is better with bass heavy genres and with poor masters. I may end up selling the LCD-3F but it would only because I want to fund other purchases (like a 3D printed tonearm for my turntable).

That's not fair comparing an unbalanced headphone and a balanced one through the ragnarok, an amp that's supposed to sound way better on balanced mode. I'm glad that you did like the hd650 more though.

Can you use a soldering iron? If so, re-terminate. Don't waste your money. The stock HD650 cable is pretty good.

Got my stock cable today and stripped the wire after cutting the connector off. One side has red and copper  wire, the other green and copper. I assume the copper on each side are ground and the colored wires are the signal...?

What planar do you think would compliment the hd650+hd800s?

I am looking for something with that super tight and punchy bass that only planars have for electronic/hiphop

(oh and no ching chong 1000s and no abyss 666s)

as I see it I got a few options:

lcd2 pre fazor
lcd3 pre fazor
he560
he6

any im missing?

ESP900 has lots of midbass, but similar to other stats, not much punch or impact. Also has massive bass rolloff so there is no low bass. A high grade LCD2r2 pre-fazor might be the ticket. HE6 is another possibility, although in stock form, the treble behavior is rather inscribed. You'll need a lot of power for HE6 not to have flabby bass.

I have half a mind to sell my HD800's and get a pair. Too much fuss, too little time and money to get it right makes the 650 very appealing...

Edit: Went and got my 14-15 year old 600's back from my brother and damn... They sound really nice out of the bh crack. Goosebumps... Need to do the spring fix though, only the stock cable works semi reliable with some tape.

If i get the 650 drivers how close will it get to a 650?

I imagine it should sound the same. The drivers are sold already installed in HD650 baffles. The only things remaining from the HD600 that could affect the sound would be the grilles and earpads. Aren't those almost the same between the 600 and 650?

Aha i did not know this, i imagined if there was any difference besides the driver it would come from the baffle/mesh. So this is good news!
Another thing though.. Should i worry about driver matching since they don't come in pairs?

Depends on how much you trust Senn QC  :)p1

It has to be better than Beyer, but that isn't much of a data point. Honestly, if you are willing to sell your HD800 I would think its worth getting an entire HD650 next time it goes on sale, and then selling your old 600 if the 650 is to your liking.

I heard OJ was going to do a driver transplant to see if anything sounds/measures different, but have no idea on timeline.

Will the HD 650's transient response (especially in the bass) be quick enough the tremolo picked down-tuned guitars and double kick drums of old school death and black metal? I am contemplating picking up a set up open cans for various reasons.

Senn's QC is the best in the business. Only the HD 650 and HD 800 have handmatched drivers but the HD 600s and 25s still put Beyer and Audeze to shame.

Absolutely! I listen to a lot of metal and progressive metal and it handles kick drums really well with fast response and not over-bloated.

Even for albums with actual acoustic kicks like Motorhead's Overkill/Ace of Spades and Immolation's Dawn of Possession? Where you can hear that 16th and 32nd notes are softer than eighth notes? I'm sure it would handle typewriter kick samples (Morrisound death metal and modern sterile computer metal) with the bass sucked out of them fine. I'm just nervous buying the HD 650 due to all the reports of them being slow despite needing an open neutral to warm headphone with no treble emphasis or ringing. The ringing and treble on my HD 25s is driving my allergy and childhood infection caused tinnitus nuts. Parametric equalization just ends up highlighting the ringing!

I have an O2+ODAC combo I bought as my last few laptops' Realteks had a ton of annoying background noise. The one in my Thinkpad T440s can't even drive portable headphones to an acceptable volume with not slammed recordings like 80s CDs. The brightness will mesh well with the laid-back upper mids and treble of the HD 650?

Tried the original black driver version vs the new 2014 silver driver, black box version (which I had never heard before) Sunday at Capital Audio Festival. The silver driver black box version sounded almost identical to the HD 600 but with better bass and no shouty upper mids and treble peak to make sparkly cymbals sibilant. I liked it so much it's my favorite stock open headphone now for rock and metal (replacing the HD 580/600). I even bought it with same day shipping on Amazon, MSRP be damned.

I bought them at almost $500 a couple years ago and they've been my best headphone related purchase ever. No regrets. The HD650 is the only piece of headphone gear I've never wanted to replace.

i honestly think i prefer my 650s with 90 percent of my music compared to my hd800s. ( hd800 fanboy for a longtime)

dont get me wrong, hd800 is  technically a better overall canbut the hd650s are just so musical and nice to listen to, they make my foot tap I just forget about listening and enjoy.

I have only been hooking up my hd800s for critical listening and with well mastered music.


hd650s are imho the best all around can ever. (have not heard ching chong 1000s or abyss666, stupid prices for them too) Also not gonna include the 009s simply because for a setup your at 10k, (iggy,009,bhse) for that kinda money mine as well just get speakers imo

If Axel grell could make a hd900 with the mids and treble of the 650s and the bass and soundstage of the hd800s would be the perfect headphone IMO

everything and anything really, the only thing i dont really like the 650s with is edm or hiphop/rap/rnb, since the bass is well, mid-fi

I'm probably just in the honeymoon phase and will revert back to my hd800s eventually as my daily driver

im getting my iggy/rggy tomorrow from schiit. Am interested to test the 650 on the rok.


two more thing on my checklist are:

an eddie current tube amp
a planar can with visceral punchy bass,  most likely will grab the he-6 since the rok can drive them phenomenally

my setup will be

computer>6 jitter bugs(one for every usb port)>geeklps4>lightspeed10g cable>schiit wyrd>uptone audio regen>.....




Jkjk

computer>wyrd>iggy>rggy>650/800 (balanced with modded stock cables) interconnects just standard snake oil free canare cable with  neutrick xlr connectors and monoprice usb 2.0 cables

also will be using the kef ls50s and some old Yamaha studio monitors hooked up to the rag

pretty good reference rig, I think. Again Id like to add a EC tube amp and an He-6 for it to be complete



portable rig is pretty crap right now

fiio x3ii (terrible) > dununnununununu2000j/UERM

I just got a cayin n5 in today, I will probably right a review on it if its good, if not, I likely wont bother. It is a very interesting little DAP though.

Can the Rag drive HE-6 phenomenally?

Rag has no problem driving HE-6. But hard to say if you will like the sound or not. Some people like it. Some people don't.

There was a mid-line Krell much lauded by the HF crowd for HE-6. It sounded like shit. That Krell made a bunch of farts with the HE-6 in the bass on a Daft Punk album and was bested by a 3 watt tube amp during the same listening session.

A passive preamp into a Pass amp might be the phenomenal setup you are looking for. It's all relative, based on personal preferences, and how much you want to spend.

What amps do you recommend for the HE-6?
I found them just a tad too bright sounding with my Mjolnir.
I've been looking for an amp for a week now. First Watt has a M2, but then I need a preamp.
My budget is around 2-2,5k.

Hi guys,

First post here, i've read all thread and decided to buy HD650 (previous cans not by order: portapros, Grado sr80i, Fidelio x1, HD598, V-Moda M100, Beats Solo 2) and Fidelio X2. I've had my HD650 (w/ shiit modi 2 magni 2) for three weeks now, and got X2's just a few days ago.

And i like X2's more.

I'm not an audiophile by any sort of definition, i just like listening to music. To me, the biggest difference is bass and probably the soundstage if i understand the term correctly. HD650 feels very.. narrow? It's like the music is very close to ears (obviously not closed-cans close), but at the same time very distant if that makes sense? It's right HERE, but not really. Very strange sound. And it becomes even more apparent when i put on X2's. They sound really wide, i can't even tell where the sound is coming from, because it feels like sound originates somewhere outside the cups. The bass is superior, it had more punch where it needed. Also, X2's draws you into music, while HD650 produced music disappears. It's not engaging.

The only thing i don't understand is why i hear background hiss with X2's while HD650 keeps it clean.

What should i do changstar? I don't want to choose the wrong one, and i took HD650 to leave the mid-fi purgatory. But it seems X2's sound better for me. Thank you.

You shouldn't be using high gain on the X2 because they're very low impedance. Do you have the switch on the Magni 2 flipped for high gain (rear switch)? The 600 might need it, but the X2 definitely shouldn't use it.
Title: Re: The Amazing Super Duper Underrated HD650. A Headphone That Kicks Serious Ass.
Post by: ultrabike on September 04, 2015, 07:25:22 PM
Based on specs, the X2 may have more bass than the HD650. But not necessarily higher quality.

If you are using high gain like Luckbad said, it is possible that you amp is in high impedance mode (not sure what the output impedance of the Magni 2 is in high gain). Note the X2 has a large impedance hump in the bass area but still south of 45 ohms. This can result in even more bass out of the X2.

So probably you like cans with more bass presence. This may not always be your preference and may become old.

As far as hearing things inside or outside the cups, I'm not sure what to tell you. Soundstage is not something headphones do great in general. But I personally find my HD600 engaging. If you find the X2 more engaging then keep those..

The bass is superior, it had more punch where it needed. Also, X2's draws you into music, while HD650 produced music disappears. It's not engaging.
It seems to me that the X2's may seem to have more perceived bass response with the Modi2/Magni2 combo. I haven't heard the HD-650's driven by the Magni2 myself, but I have heard the X2's, and did notice their bass.

As for the soundstage, maybe just double check that the HD-650's are wired properly... the connectors on the left and right side at the bottom of the headphone cups should have "L" and "R" facing outwards. If one of them was inverted, it might cause them to sound screwy. It's a long shot, especially since the connectors are pinned in different sizes, so someone would have had to jam the connectors in improperly.

If everything is connected properly, maybe you just perceive the soundstage of the X2 to be wider... it's entirely possible. Soundstage with headphones can be a subjective thing, although there are generally accepted perceptions. I personally find the soundstage of the 650's to be entirely comfortable, they don't sound congested or flat to me, however I do know that things change depending on what is driving them. It sounds to me like you might just prefer the X2's.

You may also find that it takes a while for your brain to adjust to the differences between the headphones. I know a couple of people who have a preference for headphones that have a lower bass presentation, and higher treble as well. The 650's may not seem to reach as low or high, but the beauty in the 650's is resolution throughout their entire presentation. I'm not going to say to force yourself into preferring them, but maybe give yourself a good week with them exclusively, and then go back to the X2's and see how you feel. Or maybe you already have... my subjective opinion of the X2's was that they lacked the resolution I hear in the 650's, which translated to me as muddy/wooly/congestion - silly words, but ultimately I preferred the resolution of the 650's, their linear sound, their lack of fatigue, and quality of bass, vs quantity.

This is interesting. Sonarworks averaged FR measurements of new HD 600s and HD 650s (2014 black box, silver driver) confirm that I heard in a recent comparison. Almost identical mids except for a few db less forward upper mids and slightly dark in the treble where the HD 600 is slightly bright. Blue is HD 600, red is HD 650:

Note the X2 has a large impedance hump in the bass area but still south of 45 ohms. This can result in even more bass out of the X2.

Thanks, that helped, no more background hiss. I thought it should be really easy to fix because i couldn't find this problem on the internets regarding X2.

As for the soundstage, maybe just double check that the HD-650's are wired properly...

Yes it is wired correctly and i'm putting them on correctly on my head. I don't think i'm imagining things, HD650 sounds narrow and a bit congested? I cannot believe i'm saying this but i get more instrument separation and music is a bit more revealing with X2's. I think the bigger soundstage helps to separate instruments better.

For example "Last Chance to Reason - Adrift I: A Vision Begins" (got the album from recommendation thread) sounds a lot better on X2's. On both of them i can tell the instruments apart, but on HD650 it seems they come from the same place, basically sounding like a total mess, while on X2's i don't even have to try because instruments are in different places in space. I hear the bass is behind my head, cymbals on the sides, high notes more inside ears while all midrange is in front of me. HD650 most notably Left and Right side.

Obviously i'm alone in this so maybe i'm doing something wrong. I have Foobar2000, choose output device as USB Modi 2, play HD650 on High Gain and X2's on Low Gain. I haven't done any modding, because i'm still deciding on which to return (and i don't think i should do any modding for HD650 to sound better than X2's?).

Do i have to re-educate my ears? I think i've read enough of this forum to trust all of you more than Tyll or head-fi or headfonia. And the consensus seems to be that the setup i have can be an end-game for non-audiophile.

Ninja edit: Can someone suggest me an album, or a single, which should definitely sound better on HD650? Thank you.

Honestly, I tried the original Schiit stack (first gen) with my HD650 and returned it. It could be that the pairing is no good, or maybe you just prefer the X2.

People say the 650 scales well, meaning that with better quality music files. dacs, and amps, they keep sounding better. I've recently found this to be true.

I don't have any links to lossless music files (e.g. Flac) to test, unfortunately. I love rock and blues on these cans, so maybe poke around for high quality recordings of that. My favorite album to listen to on them is Stevie Ray Vaughan and Double Trouble's Texas Flood.

I think so. But you should also give it some time and try things out with a wider selection of genres and recordings.

Or you just prefer a brighter more forward sig. IME the HD650 is better at disappearing and letting you into the music despite the slightly dark sig.

IF the X2 sounds better than the HD650 to you then simply keep the X2 ?

Both are good headphones but have different properties/sound signatures.
Whatever fits YOUR taste better is what you SHOULD be using.

Last time I auditioned the X2, it was indeed a bit too cloudy on the bottom end, and a bit too sharp at the top end. Soundstage was more... well, reverberating, and it didn't sound natural to me. Something about the upper end is just weird.

And at higher volumes, the midrange is grainy. In contrast, my HD600 is much smoother, much cleaner down at the bottom, and with a more natural, less forward/wonky/reverberating soundstage, and yet that soundstage was also bigger.

So... I think that if HD650 is not to your taste, then HD600 should be, and while I don't think the X2 is a bad headphone, the HD600/650 are just exemplary for their price.

Do i have to re-educate my ears?

This is just an opinion: You don't have to do anything. Pick what you like and enjoy.

Now, do I agree with your soundstage issue assessment? No. Do I think the X2 or the HD6x0 can provide amazeballs soundstage? No. They can sort of do it, but to me there is no headphone that does soundstage really well. For that, get a good set of speakers or put some serious $ into a Realiser A8 system.

I will however provide you a POS your-boobs link with a song that I feel has reasonable soundstage  (you may disagree and/or have better examples):

https://www.youtube.com/watch?v=bqIjOZf-0us

I place vocals to the left and acoustic guitar to the right. Bass to the left of vocals (though things start get more omnidirectional with it). There is another guitar to the far left. Crowds all around.

Naw you probably just have a preference.  I haven't heard your rig in a while but if you're happy with your set up, who cares what the internet says.  I didn't the x2 was bad when I heard it, but I do like the hd650 better. 

Bottom line if you like the x2 in your setup now stick with that, if you change in the future that's future you's problem

Ey, you can trust Tyll, well about Headphonia, IDK, I don't read it that often and there's more than one writer there, head-fi, well most of the times, no.
But yeah, this is a cool place to get a lot of info, probably because no one word is law,

And i like X2's more.

I'm not an audiophile by any sort of definition, i just like listening to music. To me, the biggest difference is bass and probably the soundstage if i understand the term correctly. HD650 feels very.. narrow? It's like the music is very close to ears (obviously not closed-cans close), but at the same time very distant if that makes sense? It's right HERE, but not really. Very strange sound. And it becomes even more apparent when i put on X2's. They sound really wide, i can't even tell where the sound is coming from, because it feels like sound originates somewhere outside the cups. The bass is superior, it had more punch where it needed. Also, X2's draws you into music, while HD650 produced music disappears. It's not engaging.

The only thing i don't understand is why i hear background hiss with X2's while HD650 keeps it clean.

What should i do changstar? I don't want to choose the wrong one, and i took HD650 to leave the mid-fi purgatory. But it seems X2's sound better for me. Thank you.

You didn't choose wrong.

I wouldn't argue against the points you brought up with the HD650. Stage is narrow and depth is flat with HD650s. HD650s in stock form are a bit overdamped or boring (hence the mods I suggested, although I wouldn't suggest mods because the differences are not huge). The X2 are more efficient (the noise you mentioned) and more fun (which equates to a bit too much boom and tizz for me).

Not going to suggest that you spend more money on stuff, but keep in mind that some of the folks here running the HD650s are running them off seriously good DACs / amps. The "scaling" thing is very real; and from what I've noted, a huge reason for many discrepancies. Even then, among the guys who have TOTL type rigs, there are a people who prefer the "lesser" HD650 over the superior HD800, HE1000, or LCD3.

HD650/600 is harder to drive than the HD800. The X2 is very easy to drive at 30ohms and 100dB. If you are planning to stay with the magni/modi stack and prefer bigger bass, the X2 will be more ideal for you. No track will change the fact the HD650 is one of the hardest phones to drive out there. Eventually the 600/650 will out image and resolve the X2 considerably with a cleaner and more precise signature among other things.

Post by: Solrighal on September 06, 2015, 08:34:11 AM
I also agree that the perceived soundstage is not the 650's forte. They've been described elsewhere as having a "three blob effect" and I'd tend to agree with that. If you're listening to large scale orchestral music these are not the headphones you're looking for, but, if more intimate music is your passion - say small scale jazz or folk music - the Senn's could be right up your street. Certainly this is my experience anyway. I also agree that they scale really well too. When I moved from an O2 to the Project Ember MkII it was the closest I've ever came to experienceing the mythical "night & day" upgrade.

Still, they can be tweaked to sound even better in my opinion with the judicious use of a parametric EQ. With the help of Frans (Solderdude) I came up with these settings..

Low-shelf filter of +2dB @ 20Hz with a Q of 1
Mid-range cut of -5dB @ 150Hz with a Q of 0.5
High-shelf boost of 1.5dB @ 5000Hz with a Q of 1

I'm using a Mac mini as transport and JRMC19 as my player. Source is an ODAC.

Using these settings that upper-bass bloom is removed with a little more weight added to the low end. The treble also gains just a little bit more air. I also use crossfeed so if you don't you might want to change these settings slightly. It's also worth remembering that I'm using a tube amp which inevitably colours the sound in it's own way too, depending on the tube used. For the record the best combination of tube & EQ I've come up with thus far has been using a 1951 Sylvania 6SN7GTA 'Chrome Dome'. My HD 650's are the silver driver version and have not been modded in any way.

I know there will be purists who'll recoil in horror at the idea of using EQ and that's fair enough. I don't have a problem with it because I consider using a tube in the first place to be a form of EQ so what the hell. I'd be interested to hear what you guys think.

Nothing wrong with using EQ if it gets you the sound you're looking for, i also use it for some problematic headphones that are beyond modding or just not worth the effort to do so.

The soundstage and speakers in a room tuning of the 580/600/650 series makes them better for studio music than the HD 800 and HE1000, technically better drivers be damned. There is no artificial width that can put the plucking of the guitar string and distortion in different places or break up the drum kit like an AKG or HD800: different drums panned to different places is seriously messed up on these. I also don't feel the 650 is overdampened for rock and metal; I found long term listening (hours a day, almost every day) of those genres' forwardly miced and mixed drum kits to be slightly grating on the slightly bright 580/600 but perfect on the current slightly dark 650. It lets you disappear into the music without fearing some animal high hat basher is going to ruin your hearing. The veiled black driver one sucked though so thanks for starting this thread which led me to give the current version a try. If you only listen to an occasional rock album you might prefer the HD 600 as it will make the kit sparkle a tiny bit more than on the mix. For orchestral music? Yeah you might something wider and brighter too but I preferred intimate material like the Kronos Quartet on my "metal cans."

The scaling is huge with recordings too. Mixes and masters start to mean a lot more. I've even found the HD 580/600/650 drivers to scale the tone better guitar amps used for tracking in a more lifelike way than lesser midprice headphones. They really make it clear how much better just plugging into a JCM 800 head sounds than a crappy Valvestate is and expose studio tricks like digital reamping.

I've not completely made up my mind yet, will give a few weeks listen between them both to decide. Thing is - just read a thread on neogaf where a guy claimed fast food tastes infinitely better than any home-made food he tried, ever. Which is absurd. So, of course, he got a lot of posts regarding his fucked up palette, that he's addicted to salt, sugar, and all the other additives that comes with their meat. Bam. Maybe i'm the same with music, i'm addicted to colored sound. Can't deny listening to really bad headphones in the teens, mainly in 5-15$ range. Though i tried M-100, and even upon believing it was the best sound i've ever experienced i had to sell them because they became really fatiguing over time with their fat bass.

Interesting bit - had a few friends come over to test them both. The girl who listens to Beats preferred X2's and the guy who had his Grado SR-60 for 12 years preferred HD650. The girl said the biggest difference for her was how sibilant female vocals sounded on HD650, almost piercing. The guy listened to Lapalux and Unknown Mortal Orchestra and really really really liked HD650 because he heard more of the music he was listening for years. Also thought that drum beats sounded very natural and warm, soft, really tasty (i don't know the real terminology for what he described). I suspect because Grados sounds very "cold" and "hard" relative to senns.

If i would keep HD650 over X2's, i would need to upgrade over time. What would be the next step for DAC and AMP? And what should i expect in terms of sound improvement?

By the way, comfort wise HD650 is like pillows to my ears. Never wore anything more comfortable, i didn't even need to stretch the metal band. I guess it could be because of my German grandfather hah, who knows.

Gumby DAC plus some sort of SE or limited to no feedback tube based amp.

The real questions you need to answer first are what sound is your sound and what are you listening for? What sort of music quality does most of your preferred music have? Can you stand to hear flaws in recordings or do you want to just listen to everything without worry?

Depending on those answers, your solution could be real cheap or real expensive. Perhaps you are already where you want to be too.

I started with my HD650s paired with the Modi 2 / Magni 2 (non uber).   My first upgrade was to the $120 Vali - I did notice a difference (improvement), although somewhat subtle, between this hybrid tube amp and the SS Magni 2.  Somehow the music seemed deeper.  This was my first experience with anything tubey, and convinced me to get the $350 Valhalla 2.  The improvement with this amp was much larger than with the Vali, and easily noticeable. Highly recommended around here, and I can vouch.

I was advised to upgrade Amp before DAC.

Actually it's very situational:

Metal (Slipknot, Animal As Leaders) - X2
Rock (Pure Reason Revolution, Bad Suns) - X2
Pop (Lana Del Rey, Florence + The Machine) - X2
Electronic (Daft Punk, Rƶyksopp) - tie
Soul (The Internet, Jamie Woon) - HD650
Trip Hop (Bonobo, Massive Attack) - HD650
Hip Hop (Onra, Flying Lotus) - HD650

Most of the songs could go either way, it's not like one or the other sounds so much better or worse. I feel like electronic music with a lot of bass goes better with HD650, because then i can counteract the low end, and vice versa with instrumental music and X2. I don't know if it's right but that's what i take from this list.

But the biggest difference i feel when listening to Animals As Leaders. It's right there, the thing why i prefer X2. It looks like HD650 doesn't know how to behave when playing AAL. It sounds just wrong, i cannot understand the music. It sounds cleaner, but with that everything sounds "at the same time" with nothing being accentuated, nothing to grab onto. I now know how complete chaos sounds like.

Doesn't help that the AAL album doesn't sound particularly good from a recording/mastering standpoint, especially on headphones. With that track, I have no issues picking everything out on the HD650, nor is there "nothing to grab onto." It's just a really messy, compressed, in-your-face master. You might do well trying the mods listed on the first page, if I can imagine how this would sound on the stock HD650. (Note that my comments have nothing to do with my subjective thoughts on AAL. I like some albums with crap mastering too.)

I'll give you that the X2 sometimes did a better job with staging and imaging over the HD650. Some of that was the design in terms of driver angle, driver placement relative to ears, and housing, and some is the accentuated bass and treble spots that give that sense of make things "pop" in a way that seems to cut through everything. If that makes sense... It's just, at the end of the day, the bass was way too fat on it for me, and there was a sharp treble spike that started to get bothersome rather quickly despite being exciting at the start. Plus, after further examination, it became pretty obvious it wasn't as technically capable as the HD650, general frequency curve aside.

Again, YMMV depending on what gear you feed the HD650. Much pickier than X2 and much more technically capable in nearly all regards the better your setup. The DAC/amp combo you're using is certainly a great budget setup, but it's not going to get the best out of the HD650. It generally only tends to falter slightly with staging and bass quality.

What realistically could i expect if i'd get Valhalla2, and would keep modi2 (or upgrade to Bifrost)? Gungnir would be out of the question for now. Would i get better imaging and bass depth?

I think others can do a better job of describing the sound differences between Magni2 and Valhalla2 (with this HP).  But FWIW, I am running the rig you describe, Modi2 -> Valhall2, -> HD650.  I find that the Valhalla2 is really noticeably sweet with small ensembles, like chamber music.  There is more instrument separation, resolution/detail throughout, and it feels more immersive.  All genres benefit to some degree, but genres that have subtle dynamics are where I hear the improvements.

But I don't think the soundstage will ever be much larger. Can you keep both the X2 and HD650?  They might be somewhat complimentary - X2 for a livelier sound, HD650 for more resolution, more cohesive...

WELL NOTHING IS BEING ACCENTUATED! It's djent so shitty solid state head that means the guitar tone lacks dynamics and then you have brickwall mixing and mastering that is using dynamic range compression to lower the peaks of everything else to the guitars so the drums aren't dynamic (if they weren't already sample replaced) and then slamming the shit out of it. Be thankful the instruments are relatively audible and it isn't clipped!

So in essence X2's "coloring" of the sound fixes the music somewhat and helps bad recordings to sound better while HD650 needs to be feeded only good source files to shine? I'd guess the better staging helps as well. Makes sense.
The V shape of the headphone is making the emphasized bass bring out kicks and the treble might be making the shelved snare and cymbals stand out. On well mixed records the bass will just be too boomy and the treble will make lofi records unlistenable. Animals as Leaders' production sucks but the recording isn't truly offensive. You probably wouldn't want to listen to any metal classics with truly fucked up productions on the X2, eg. Norwegian black metal, Demilich's clipped drums, Carcass - Reek of Putrefaction.

The HD 650 is super helpful for Immortal's glassy, television static rhythm guitar:

?????? Misquote/misreading? I never said they couldn't. I just said they had a more intimate soundstage compaged to AKGs and flagships which is a positive for studio music. I think they sound perfectly fine on my O2

Sorry, I guess I should have worded that differently.

The HD600/650 will only sound intimate until you drive them out of certain rigs, and then you'll see that they don't sound so intimate anymore. In fact, they'll squarely beat many headphones that are known to produce "good" soundstage (prime examples being HE-560, Fidelio X2, etc...) once you get them on the right rig.

Honestly, I didn't know that was even possible until I heard it for myself. The HD600/650 are capable of soundstage that's probably second only to HD800 and a few more headphones.

What's your opinion/recommendation on a rig that can do that for the HD650?

What's your opinion/recommendation on a rig that can do that for the HD650?

I've heard (so far) these 2 rigs that can achieve that on a stock HD600/650:

Bottlehead Crack w/ mods + NAD M51 (pushes the soundstage much deeper, but not wider)
Eddie Current prototype amp + Schiit Yggdrasil (pushes the soundstage in all directions and makes bass much cleaner)

Aside from that, a modded HD600 (and potentially a modded HD650, though I haven't heard Marv's mods) can probably achieve that as well on a wider number of amps.

This is without any (or much?) tonal or frequency change, of course.

About the HD650 soundstage and scaling...

Today I picked up a Focusrite 2i2 because I want to use REW/ARTA and my current ADC (TASCAM DA-3000) does not do USB.  My calibrated mic is still in the mail so naturally while waiting around I did a little A/B do see how the DAC/amp combo compares to Yggy/Rag. 

No surprise Yggy/Rag is (much) better everywhere but the biggest difference happens to be the imaging and soundstage.  Yggy/Rag (probably mostly Yggy) gives the HD650 a super wide stage which completely goes away once you switch to the 2i2.

Tried with LCD-3F and the effect is still there but not quite as pronounced.

So, i've been listening a lot to both of them and have found out that the soundstage makes a very big difference in perceived sound quality. Here's a few pictures of what i hear.

(http://113.imagebam.com/download/_ahRYietM5n9ZS96RZz4sg/43438/434372435/X2.jpg)  (http://114.imagebam.com/download/IrfuAniRxBYQ2fn7Ps_EuA/43438/434372438/HD650.jpg)

While it is not always the case, i' believe these could be called their "native" soundstage.  I feel like X2's sound surrounds you, wraps around your head and sings. You have a much needed space in the middle, and music is further away. HD650 sound originates in your head, between the cups and there is no room for "you", the centre of head is mainly occupied by in-your-face vocals, like the singer is singing half an inch away. I listen my music at around 70dB, but for testing purposes i cranked that up to 90-100dB. On HD650 the vocals basically took over the song, and started to sound piercing like my friend has mentioned. I could crank up X2's to infinity (not really) without feeling anything like that.

I also found out why HD650 sounded better when switching the music. On some tracks X2's soundstage shrank to HD650 level, and then the latter has a field day. When X2 soundstage is small like sennheisers it sounds too fat, it cannot perform good if crammed in small space. The worst is when i listen to hip hop - X2 is just awful. Overly warm, bassy nightmare. Two examples where HD650 destroys X2 (i have high quality source of them):

http://www.youtube.com/watch?v=UenZSpYkAKkhttp://www.youtube.com/watch?v=7qwNZW2lJlU



X2 destroys HD650:
http://www.youtube.com/watch?v=yOuGvBuTFTchttp://www.youtube.com/watch?v=V3m3WbL9V5k

I believe X2's have a leg up on certain tracks over HD650 not because of the bass or the fun factor, it's because of the soundstage. I cannot understand why such narrow soundstage, for an expensive can like that, is accepted as normal. No one talks about this issue. Before buying, i haven't read anything like this. HD650 is not a closed can, and i'm not saying it sounds like one, but it should be definitely its forte as an open HP.

Obviously i'm not an audiophile, and this may sound very stupid for all i know haha. But i challenge your recommendation for a "budget audiophile headphone". It should be X2, which is cheaper by itself, and doesn't even need 200$ dac+amp to achieve comparable sound.

You're right, the two shouldn't be compared. The X2 is colored and the 6xx are more neutral/reference. If you don't hear sibilance in female vocals on the X2 it's because of the -10dB at 3khz and massive -20dB trough at 6khz hiding the recording flaws in her vocals. The easier to drive X2 also have an advantage with a boosted 5dB at 100hz wrt your hrtf versus a the Senns which are more linear and with less than ideal power need to be cranked up making more flaws obvious. I also wonder if you matching true levels or rather bass levels. How are you coming to your 90dB figure btw? Do you own an SPL meter?

Th 6xx is not an entry level recommendation. It is a mid-fi to even top tier recommendation for people willing to drive it well and use good sources. It was never recommended as a headphone that can sound best from your iphone like an x2.

IME and IMHO your tastes (atm) are for euphonic coloration and hiding recording flaws and have yet to hear the Senns close to their best. Trying to find a different result using your same gear, methods and preferences is the very definition of audio insanity.

Even if the Soundstage width never gets as wide, when they scale the Senns will image and resolve far better than the X2 and run away from them.

Feel free to use whatever makes you happy. But if you want to challenge and champion the X2 as ultimately a better performer over the Sennheiser HD6xx? Challenge accepted.

This definitely makes sense.

Haha no, the best i could do is use an app from a smartphone and shove it between the cups. I know it's not ideal but the main take from that was harshness on vocals when cranking up the volume.

Th 6xx is not an entry level recommendation. It is a mid-fi to even top tier recommendation for people willing to drive it well and use good sources. It was never recommended as a headphone that can sound best from your iphone like an x2.

HD650. Schiit Magni + Modi. $99 + $99. No kidding. No schiit. No risk other than shipping costs.

Sounds like a budget build suggestion to me, otherwise you'd recommend to return HD650 if someone's not ready to spend serious cash to drive it. I would argue that two times cheaper option is definitely a better buy while getting arguably better sound.

Also, just watched Tylls X2 review, and at the end of it he basically said that X2 is a better buy if you dont want to invest on very good dac and amp. Someone said a few pages ago that this is the guy to trust.

This is how I found the HD650 to image, until I removed the foam discs at the back of the drivers, as described in OP. I have the transparent drivers, silver metal-like screen version, drivers have october 2014 printed on them. I realize these are there for a reason and for it to measure as sennheiser intended, yet at least to my ears the drivers sound starved of air to work with, having so much damping in place (THREE foam disks in mine). If you're careful these come off without problems, and if you're patient these could go back in easily, too. 100% reversible. I didn't punch the hole in the front foam.

After taking these out, the soundstage expanded a lot in all directions, instrument placement became better, too. A nice improvement all in all, in all areas, and I could start appreciating better what these are capable of (I also felt the sound was more worthy of the price tag after the mod). A little more bass and impact, yes, but that doesn't bother me, if anything it adds to the already excellent signature these have... eargasm is all I can say.



Source is a Xonar DX (CS4398), amplifier is a DIY SMD version (just took the schematics and did my own PCBs) of "The Wire", SE-SE (http://www.diyaudio.com/forums/headphone-systems/179298-wire-ultra-high-performance-headphone-amplifier-pcbs.html) plus a better PSU. Better source is up next sometime in the future, for now it's endgame for me and my budget... have in mind I stepped up from the PX100, lol... I had been eyeing the 650s for the past 5 years, a chance appeared and got them for my birthday. I couldn't be happier.

I'm not sure where these "closed can" "narrow soundstage" issues speak is coming from. An HD650 is not a closed sounding headphone even from my 2i2 or indeed the headphone output of my POS laptop.

If you were complaining about bass being un-refined or sub-bass, I would understand.

Furthermore, your X2s are about the same price as an HD600. So, I'm not seeing the budget improvement.

For lower impedance, and much lower $ get an HD558 and even then I would be surprised if your X2 did better than that.

I have an AKG K7xx with me that sound more "alive" I guess. But soundstage is shit out of every headphone I've heard with the exception of a pair of cans driven by the Realiser which indeed fooled me into thinking sound was coming from the freaking wall in front of me.

Differences in how we perceive stuff are more understandable to me if we were talking about IEMs. But these are full size open cans. I'm more inclined to believe that you just like a particular coloration and are a bit confused about soundstage.

This bass in the back, strings on the side and vocals in the front from an X2 sound like complete BS to me. Frequencies in strings overlap with vocals. Even drums have mids. So you would hear sound from drums partially coming from the back and partially from the sides. Vocals have somewhat different ranges. I mean, if what you say is true, the X2 is a complete cluster fuck.

Yes, I'd agree with that and Tyll. Still it's a matter of tastes too. I can't speak for Marv, but I think his cans are modded and he's not saying that's the penultimate combo, just that it works. That suggestion leaves you room to upgrade in the future, the X2 won't as much.

Personally, If I preferred staying with the $200 schiit stack and wanted neutral sound with wider SS I'd look to the HD558/598. Much cheaper than the X2 or 6xx on most days. Won't be as warm, forgiving or bassy as the X2 though.

Well, there was talk on the X2 making the Leaderboard a few week back. It was pretty close, until I personally decided to nix it. Your (foxfluent) arguments have almost convinced me to reinstate the X2 perhaps on a conditional basis. My reasons for nixing the X2 as Leaderboard material were as follows:

But even with the slanted baffles (like the HD558s), the cross channels are missing (among other things).

I'm not saying the X2 is bad. But I don't get this uber selective strings-are-here, vocals-are-there, my-dog-is-way-back-there with the X2 but not with the HD6x0. I'm more inclined to believe the X2 is a bit more forward in the treble, upper mids and bass. In other words, more fun.

Plug HD6xx into 445 and highly resolving DAC and experience 2nd best soundstage/imaging (HD800 is #1) that I've ever heard.

Accurate-to-the-source soundstage that is. X2's tonal colorations can make soundstage hyper-active but ultimately miss cues.

People can hear soundstage on various cans differently than others. Just changing how you wear headphones (high/low/forward/back) can make a difference. I don't have long hair, but I imagine that can have an impact.

Two days until i have to return HD650. Might be my last chance to try or i'll never know, though Marvey said it wouldn't make that much of a difference, if it does in the soundstage, i would definitely notice. I'll sleep over it.

I'm not sure where these "closed can" "narrow soundstage" issues speak is coming from

I'm trying to read the glossary, but i've just started talking about what i hear, so it's hard. There's two reference points for me, X2 and HD650. I hear HD650 "inside" my head, while x2 "outside" my head. It makes a huge difference in half the tracks i listen. It could be that sub-bass helps to create this effect. I don't know.

This bass in the back, strings on the side and vocals in the front from an X2 sound like complete BS to me

They overlap strongly and make a circle? It's obviously my fault that i can't communicate fluently about this topic. Sounds good though.

HD558/598 would not be able to perform on a lot of tracks i believe, especially considering more contemporary music.

Your (foxfluent) arguments have almost convinced me to reinstate the X2 perhaps on a conditional basis. My reasons for nixing the X2 as Leaderboard material were as follows:

I'd really think it should be there. Lets say someone wants a really good sound, something better than PX200, but not something that breaks the bank and is not planning to move up the chain. That guy searches the net, finds changstar, reads the suggestions, finds the leaderboards, buys X2 as the "best recommended hassle free cheap good sounding headphone" and you have a happy guy with a good sound on his head.

I agree that HD650 reveals more of the song even with this setup, but it's not always the case. I could write down entire albums where X2 was more revealing for me just because of that sound stage. X2 is really warm sounding HP, but not to the point of loosing clarity. Instruments sound very full and lush and clear. The biggest problem is when the soundstage of recording is cramming X2 inside the head, that's when it starts to loose clarity.

T1 is overly sharp if i remember what i've read? This is a deal breaker for everyone. Especially these days where not everyone is listening to 80's and 90's tracks. X2 on the other hand is not an extreme. It's not a boomy mess or a basshead HP. It's a good HP for engaging listen, and for background listen as well i believe.

That option is already in the leaderboards, I think. It's the Brainwavz HM5 (or the equivalent rebranded/renamed ones). It's much cheaper than the X2 or HD6x0, so definitely will break the bank LESS than the X2, it's also closed back, and the pads are being sold a dime a dozen with various colors and options if one wishes to switch styles, and it's also got a pretty agreeable sound when amp/DAC are not important factors.

Center Bullshit
Or
Why Canā€™t I Hear Better?
Recently I have been getting a lot of questions and have seen a lot of confusing arguments regarding ā€œcenterā€ imaging on amps. The argument goes something like this ā€œThe center is fuzzyā€¦therefore the amp sucks.ā€  Wellā€¦I call bullshit. Iā€™ll say it again. BULLSHIT. I don't know who has started this random bullshit but I'm sure it's someone trying to gain some important status or pass himself/herself off as someone with "golden ears". I wonder if TAS is involved?   :)p3

Center imaging is part of the soundstage and, on headphones, that comes across being inside your head or behind it. For a lucky few, it will RARELY come from infront. Wait a secondā€¦that means there is no center and therefore the amp sucksā€¦right? No. Not exactly. This is very dependent on each individual but in general, if you hear a MONO source inside your head or behind your head, itā€™s good! If you hear a MONO source more to one side than the other, there is a channel mismatch somewhere or you have hearing loss in one ear. Simple as that. The ONLY way a lucky few can hear a true center image is by using binaural recordings made using a cast of their own ears in a controlled environment.

Ideally, we would all perceive sound the same wayā€¦and guess whatā€¦most of us do! What changes from person to person is our ability to fine tune WHAT we hear not HOW we hear. The HOW is the same for all of us.
Soā€¦how do we hear? More specifically, how do we hear soundstage aka directionality?   p:8

The strongest cues for determining localization come from the differences between the signals reaching our left and right ears. These differences depend on the intensity and time differences. WE ALL HEAR LIKE THIS AND ARE DESIGNED BY NATURE TO HEAR THAT WAY.  All other cues, such as content and overall sound intensity depend on the listenerā€™s ability to tease apart acoustic attributes that are due to source content and those that are due to source position.  However, there is one catch to thisā€¦this only applies in an anechoic space.

In real life, binaural localization cues are extremely ambiguous as many source sounds can give rise to the SAME interaural differences. This leads to what is called ā€œThe Cone of Confusionā€. We don't usually experience it because our other senses help us localize sounds in this region.


(http://thirtymilesofcorruption.files.wordpress.com/2012/02/coneofsilence.jpg)
Cone of Silenceā€¦NOT TO BE CONFUSED WITH THE CONE OF CONFUSION!

The ā€œCone of Confusionā€ is mainly documented in studies of binaural sound/recording and cognitive and neural systems. This isnā€™t something I just decided to make up. Itā€™s known and itā€™s been known for a LONG, LONG, LONG time. Oh and guess what?! It's also been well documented and researched!!!

In fact, itā€™s so well documented and explained for the technically and non-technically inclined that I donā€™t see the point in continuing this article. Now that you are aware of ā€œfuzzy center imageā€ bullshit, go out and try an amp for yourself. However, before you do that, do yourself a favor and read-up and understand the non-mysterious ā€œCone of Confusionā€ then pat yourself on the back for knowing yourself a little bit better.   :money:

Cocaine. PLACEBO...it's a hell of a drug.

Consider keeping them and getting a pair of taller pads, there's someone around who installed the HM5 angled velour pads successfully which are pretty deep. I'm pretty sure they will increase the perceived width.

V-shaped sound usually makes good recordings worse and bad recordings horrible. Just because they bring out shelved drums and cymbals in slammed pop mixes where everything is lowered to or below the peaks of the guitars or vocals with dynamic range compression doesn't make the V shaped headphone better, it means your recording is poorly mixed or mastered. Poorly recorded, mixed, or mastered recordings sound poor! That extra treble will make a well miced drum kit sizzle a bit too much. If they fucked up and the engineer forgot to set the limiters on the drum mics like Demilich did on the otherwise decent sounding Nespithe? Pencil in your ear! The band has good acoustic kicks and audible bass due to being well recorded and mixed? That V will make them too boomy and threaten to overwhelm the lower mids. Soundstage? Go buy speakers.

The HD 580/600/650 scale up, sound great with good recordings, and smooth over bad ones with the HD 600 being the ever so slightly bright flavor and the HD 650 ever so slightly dark one. The X2 does none of these and has worse mids than the even cheaper Sennheiser HD 558/598 series while costing more than the HD 600 does on sale. Why should the X2 be on the leaderboard? It makes well recorded albums sound better whose drum kits were shelved to make them the overall volume initially (the listener controls the final volume) louder?

Honestly, if it's worth penning pages and drawing diagrams just return the 650 and X2. You've already made a decision at this point.  Move the discussion to the leaderboard thread and stop crapping in the 650 thread with this X2 stuff. As for me, forgiving and euphonic sounding stuff should never be on our leaderboard. Let other sites deal with that can o' worms. "But my ears like these phones for this song." Blah blah blah.

At least now we have a good example as to why the 6xx is often so underrated. ::)

What if that person plays games which need directional sound, and watches Michael Bay movies? I don't know, maybe there is no place for them after all, but the description of
AKG K7XX
Nice warm sound as opposed to the leaner and colder K701. Tonal balance less irregular than Q701. Slightly sharp and rougher in treble compared to HD600, but also less shrill in upper mids. Also a bit less resolving than HD600, but has marginally better quality bass. A Massdrop special at $200 that's hard to complain about.

looks similar to what X2 offers. And i don't think one of the big threes will be removed. No mention of the soundstage though. If there really is no place for X2, then at least descriptions should be changed mentioning each HPs imaging on budget setup.

They overlap strongly. Check this chart:

Sorry if I'm coming off strong on this. And I think I understand you well. I just don't think that what you are describing as soundstage correlates well with what I think you are hearing.

It was more of a cautious rhetorical question, they do overlap strongly but i've tried to pinpoint the most common originating points for these instruments (i'm probably getting of the rails again but oh well). And it's okay, it's been very educational so far.

Because? The HD558/598 may not be as refined as the HD6x0, but they are not too far off sounding relative to other mid-fi cans.

I've tried 598 a year back for a few weeks and my impressions were that they were very bad for EDM and a bit less bad for other electronic music. If i would have to take a guess after another 10 years they will be considered unlistenable after new generation growing up (except for us older dudes).

I've tried listening to mono audio on both HP's right now. X2 was a bit more forward in head space (just behind the eyes) while HD650 in the center of head. What does it tell us?

Consider keeping them and getting a pair of taller pads, there's someone around who installed the HM5 angled velour pads successfully which are pretty deep. I'm pretty sure they will increase the perceived width.

I'll have to think about it, but one thing i remember clearly from browsing changstar - "if somebody would've told me about HD6x0 it would've saved me a lot of money". Keep coming back to this quote, as i don't trust myself on stuff i don't fully understand.

Honestly, if it's worth penning pages and drawing diagrams just return the 650 and X2. You've already made a decision at this point.  Move the discussion to the leaderboard thread and stop crapping in the 650 thread with this X2 stuff. As for me, forgiving and euphonic sounding stuff should never be on our leaderboard. Let other sites deal with that can o' worms. "But my ears like these phones for this song." Blah blah blah.

At least now we have a good example as to why the 6xx is often so underrated.

Yeah sorry, although i think discussions are nice, it was starting to go off-topic. Will give an update on what i've chosen later on by editing this post after a few days. Thanks for patience.

Two days until i have to return HD650. Might be my last chance to try or i'll never know, though Marvey said it wouldn't make that much of a difference, if it does in the soundstage, i would definitely notice. I'll sleep over it.


On mine it definitely did, but then it came with three foam disks at the back of the drivers... excessive to put it lightly, these drivers were starved of air. The best way I can describe the effect is "compression", the presentation was too two dimensional, little depth, and too little bass impact, little dynamics... at least on my setup. Now my 650s can more easily place instruments far away in the room for example. Not that such information wasn't noticeable before, it's more pronounced now. Transients are better, too, even on a quick test from a freaking phone.

As Marvey in OP describes the 650s after the mod:

Quote (selected)
With the tweaks, the HD650 sounds faster, crisper, more lively, less over damped. I would not attempt these tweaks on the HD600 though. Overall, maybe a few db too much mid-bass, but everything else sounds just right. (I would ignore the roll-off past 10kHz in the FR graph, it's a measurement thing with how the microphone is angled on the measurement system.) Recordings which are a little bright like Midnight Oil Diesel and Dust are indeed a little bit bright. Recordings which are laid back like Natalie Merchant Tigerlily are laid-back, but not rolled off to shit. Taylor Swift's voice is a bit shouty, but not unbearably so. As I've said - just right.

Just right, everything falling into place as it should. That's it. I couldn't say the same of the stock 650s, there was something bothering me that went away after removing the foam damping. Now it's everything I've ever wanted on a headphone, and I'm more than relieved I came across this thread and followed the advice in OP. It's quite beneficial. Legendary headphones, these 650s.


I'd actually done some very rough measurements back at the time on a crappy, non calibrated cheap microphone and a cardboard box as a head with roomeq to see relative differences between modded and unmodded, I saw 2dB more bass on the 100-200hz region IIRC as the most notable difference modded that I could measure apart from what I've described so far, the rest of the FR remained almost the same. Good enough for me and my purposes, listening. Maybe the unmodded cans are better suited to other tasks that require a more neutral FR, but then we go into the never ending 600 vs 650 debate.


I've read people in this thread say theirs came with two disks, these particular 650s wouldn't have sounded so overdamped.

Obviously i'm not an audiophile, and this may sound very stupid for all i know haha. But i challenge your recommendation for a "budget audiophile headphone". It should be X2, which is cheaper by itself, and doesn't even need 200$ dac+amp to achieve comparable sound.

Meh, X2 is just way too colored for me. Again, fat, bloated bass and overly sharp treble. No idea if there is any product variance to account for subjective differences. Typical "fun" sound, which if that's what you like and don't want to upgrade your DAC and amp, by all means...Staging was really the only thing I thought they did quite well (that and the immediate engaging yet tiresome over time sound), but you can get a similar level of overall technical performance out of cheaper headphones IMO. Some give and take. Just not sure it's leaderboard material unless we want to start making exceptions to all sorts of overly colored headphones just because some people like them. And at $200-300? Just can't get on board with that, but it's not like I'm saying one can't enjoy the X2.

FWIW, I thought the HD650 mods posted in this thread were NOT a subtle change. Nor did anyone that heard my pair at the local meets. Hell, the one other guy with the HD650 at the recent CS Denver meet went home and did the mod after. But, again, it's not gonna make crap recordings like AAL suddenly sound magical. Better in the ways you want? Yes. Just not magical. But not subtle. More air from top to bottom, more dynamics, stronger bass, less of a strained sounding veil, livelier, etc.

I dunno, personally, once you hear the HD600/650/800 on a really good tube setup...very, very difficult to go back. Perhaps it's best to stay away from there any save yourself some money, no?

Another thought...screw returns. Sell the HD650 at a good price used, even modded (just don't fuck up), and you'll make up most to all of your money AND not have to worry about mods.

I have owned the HD580, had it upgraded with the new grills of the HD600, pads etc etc, and even owned the HD600 at some point.

One of the reasons why I can't like the HD600 or HD650 (Even more so for the 650) is the pressure it puts on my head. I have a larger than average head circumference, or so I would assume. As a result, the HD650 puts quite a bit of pressure on the top and sides of my head. I have tried stretching the headband, but it resulted in a broken headband that needed to be replaced.

What I am wondering is if there are any mods or any replacements for the headbands that would allow a higher level of comfort. With the HD800, the headband itself plays a role in the sound, is it the case with the HD650? Any and all inputs are appreciated.

Don't stretch the headband, stretch the metal. Fully extend it, then carefully bend the metal only (and don't touch the plastic or ear cups while doing it).

I have a giant head too, and I couldn't stand the HD650's comfort when I got it.

I actually put the headphones over the box they came in for the first couple of weeks. That helped a little and squished the crap out of my ear pads. Then I did it on the metal and it took 10 minutes. Now they are super comfy.

Luckbad beat me to it, but yes, you bend the metal, not the headband. Extend the cans all the way out, grab firmly where the metal meets the headband, and then grab the headphone part of the metal. Bend outwards until the metal is flat for a few seconds, then repeat a number of times. Do the same number of times on the other side, and try them on. Eventually you'll reach a point where you're happy with the pressure they put on your head now.

This way the headband is safe from breaking, and you get to use the pads a lot more than usual, they would flatten out much earlier if not bending the metal parts to fit one's head comfortably.

Sounds like a budget build suggestion to me, otherwise you'd recommend to return HD650 if someone's not ready to spend serious cash to drive it. I would argue that two times cheaper option is definitely a better buy while getting arguably better sound.

Also, just watched Tylls X2 review, and at the end of it he basically said that X2 is a better buy if you dont want to invest on very good dac and amp. Someone said a few pages ago that this is the guy to trust.

I don't know how applicable HD600 experience is to foxfluent's 650 experience, but I'll chime in anyway. I don't want to add another comparison strand into the thread, so let's call my previous headphones HP'Z'. I was very much enjoying my music listening on my 'Zs' and looking to make it even better. I don't have much opportunity to audition here, didn't have any foreign trips coming up, and narrowed down, blind on the HD600 or the HD650. I pretty much took advice (here or elsewhere, I forget: probably some of the same people anyway) that the 600s would probably suit me.

When I got them, with much expectation, I was not in two minds, I was in multiple minds. For starters, my "Z" had made me unused to hearing bass. "Z" had made me used to hearing highs, air and detail, and it seemed like a big difference, and I can't say that I really, really liked it.

Two things: one, I sorted out some pre-amp/amp mismatch (not applicable here), and two, I found out that the positioning on the head makes a big difference. Have you tried moving the 'phones around? For me, it works best when the head band feels a little forward on my head, and the phones are touching, even pushing slightly, the back of my ears. It is not the most comfortable position, so it was not intuitive to find it. I would guess that this is something that may vary from head to head and from ear to ear: I'm just suggesting to experiment.

I agree on the soundstage thing: I got better soundstage from "Z." But, on the whole, "Z" now lives on the shelf (just lent it to Kothganesh, just for the experience. I can't imagine that it will be very positive for him, given how many TOTLs he has heard, by still). Z on the shelf, HD on my ears. If HD doesn't do some things as well, I can live with that for the things it does better, and, bit by bit, I can upgrade the rest of the chain too.

I agree that you are coming from a sound that you like, to a sound that you don't feel as being as good. As others have said, there is nothing wrong in living with the sound that you like. But perseverance with HD6xx may just move you on into a different sound that you like.

When I got a bit serious about headphone listening, I was amazed to discover that some people have different 'phones for different music. People told me, "Nothing does everything perfectly." Well, I now own three pairs of headphones, but that's one on the shelf, one for travel, and one that is my all-rounder for home. If you have a specific requirement, like that soundstage for gaming... keep your gaming 'phones and use them. But, if, every time you put them on you sigh happily, then stick with them and be happy.

Do the yokes on the HD6x0 extend farther than the HD800? For some reason, I had thought that the HD6x0 had the same body as the HD558, but I see now that is not correct. The HD558 fit me fine, but the HD800's yokes don't extend far enough for the pads to sit correctly over my ears. Is the HD6x0 any bigger?

I have the older hd650's around 8 years old.  Was wondering if just replacing the driver would give me the same sound as the newer version that came out late last year. Apparently you can buy two drivers for $105 direct from sennheiser.  Or would I have to replace the whole cup because I also need the silver mesh?

Do the replacement drivers come with replacement mesh screens that surround the driver? That will play a big role in sonic differences.

Nope. HD650 is not a super duper overrated headphone. And no, the HD800 does not shame the HD650. In fact, I can't stand an HD800 w/o Anax's mods.

It's the whole unit with updated silver mesh (versus the old silk one)

There are YouTube vids on changing the drivers.

I got mine from the UK Senn parts store online, and they were the newer ones (don't think the old ones are sold anymore)

I'm rocking the Gumby + Valhalla 2 --> HD650's right now. Sounds fantastic. I love the warmer, musical, smooth nature of the HD650's. I also have HD800's which I'll mod soon.

Would modding the HD650's (removal of foam and the coin mod) bring them closer to the sound of Anax modded HD800's? I enjoy having some different flavours in headphones, so I actually wouldn't want to try and turn the HD650's into lesser HD800's.

Essentially, I'm pretty happy with the HD650's as they are right now, except for wishing for a little more soundstage depth.

The hd650s mods will improve the soundstage depth. But if you like the sound signature of the unmodded hd650s, the mods will bring down the mid-bass hump a bit.

This is the setup I am dreaming of.  I currently have the Wyrd + Modi 2 + Valhalla 2 --> HD650, and this is great, but I think the Gumby would be the real icing on the cake for an optimal HD650 stack.  That said, I'm just not sure I want to kick over the dosh for the Gumby; this qualifies as pretty pricey for me, so I am sort of wondering if a Bifrost Uber would get me close...

I need to hear an HD800 with Anax mods. I've heard them twice. One stock, one with some dude's personal mods.

I abhorred it. I'm sensitive to treble to begin with. Combining that with my knowledge of their price, I immediately gained a deep hatred toward the HD800. It was also a huge disappointment because I've always loved Sennheiser. I think I currently own about 5 of their headphones and use 2 of them regularly.

What's kinda cool to me about the HD650 and HD800 is that you guys who are addicted to clarity as the other side of my coin--the Basshead coin. We're willing to go to great lengths to find the potential of a headphone for our purposes and are willing to forgive stock as long as the possibility for greatness is there.

Most bassheads are super happy to use equalizers and largely use portable daps/dacs/amps. I'm a desktop guy and prefer hardware solutions when possible, so it's always interesting to me to read what you folks do to make the HD800 shine.

My Fostex TH600 have become my Basshead can that I'm working to fix. I have the same rug damping material as the HD800 in front of the drivers (helps drop the 5-6kHz heat by ~1dB) and I'm going to bug Solderdude in a month or two about a design for an in-line extension cable to essentially peakfilter that frequency down. I'm also planning on investigating filter boards for sub-bass boost (primarily 75Hz and below) without the need for EQ or a switch on an amp--I'm still an audiophile and prefer really good amps, but none of them have bass boosts integrated.

Holy crap I'm rambling super far off-topic.

I've done no mods to my HD650 apart from getting a balanced termination. I'd like to try the Kennerton wood cups at some point, but that'll have to wait until I'm done buying too many dacs/amps and selling the ones that I don't love.

LOL! I've kept my HD600 stock, and I like it that way. Perhaps it could be improved, but not too worried about it currently.

The 800 IMO does need help. Not as much as a DT990, but it does.

I heard a stock 800 with a GS-X and it definitively did not work for me. Heard the Anax moded one from Mike's Super-7 (+ other god like amp) and felt it was pretty good. Maybe the Anax moded 800 works with the GS-X, but I didn't try that.

How do the mods affect the 650's speed, Hans?  Particularly in the bass?  I know it's not the fastest hp to begin with.. even when fed ample, hq voltage.. but if the modded 650's bass is noticeably slower vs a stock 650's bass, it might deter me from doing the mod(s).

Yeah, one of the first things I noticed was it brought out the mid-bass. Can't remember if it affected the low-end slam or not, though, but I think more albums then not sound more powerful with that extra mid-bass hump. Whatever the changes were, I liked them. I suppose if you cut a bigger hole in the front foam than I did, that might reduce bass relative to stock.

How do the mods affect the 650's speed, Hans?  Particularly in the bass?  I know it's not the fastest hp to begin with.. even when fed ample, hq voltage.. but if the modded 650's the bass is noticeably slower vs a stock 650, it might deter me from doing the mod(s).

I actually think it made them sound cleaner and perhaps faster overall. They are slightly overdamped stock, very slight, which to me made some things sound a bit strained in a weird, glaring way and some things more dead than they should. Almost, almost splitting hairs here, but in a way that it still might be a noticeable gain for some like myself. They do open up after mods, though, which IMO helps some aspects come through a bit easier than stock.

Now, bass speed, I think we all know the HD600/650 don't have the absolute best bass out of every headphone. Quite good, yes, but there can be better (often with other, worse trade offs). While there is more bloom from the mid-bass hump after the mods, which may or may not be to your tastes, I haven't found the overall speed or clarity to change much down there. Think extra bloom, not looser or slower, if that makes sense. Paired with the right amp, it can shine just as much as possible down there as stock.


YMMV and your findings might not match mine. I think everyone at the recent Boulder CS meet agreed the mods really helped the HD650. Convinced one guy to mod his pair after, at least. :)

So I just cut up my HD650's.

Coin mod and foam removal from the back of the driver.

Shiiiiiiiit. No negatives, imo. More air and precision. Still got that great, smooth, HD650 sound. Bass might be a little punchier. Let's the GMB and Valhalla 2 show off even more.

If you know you like the HD650 sound, imo it's pretty likely you'll prefer the sound with the mods.

Yeah it's a pretty huge change. I went back and forth between the HD600 and 650 until I modded the 650. Eliminates the slightly overdamped character of the 650 altogether.

Punchier bass, crisper, more open. No downsides.

I am curious what amps were used by the folks who said the mod made the bass more woolly or increased bass volume as this was not my experience. I can see removal of the dampening increasing the impedance peak ~100Hz. Maybe certain amps that are more voltage limited are having a more difficult time with this.

Perhaps FiiO's portable amps or smartphones? :p
Tried the HD650 out of and E12 once and decided I will not touch the amp again.

That was me.  I have been doing more thinking and work on this so I thought I'd respond.

My source (dual mono Buffalo II's into a Lundahl LL1684 transformer) has a Zout of approx. 277 ohms.  I also experimented with an Apogee Groove (a current source, as you know). I have always compensated for the increased voltage into the headphones because of the low-frequency impedance peak with EQ to restore the frequency response.  I think this can be calculated and done with very good accuracy.

Based on your comment, I wonder if the impedance peak is being altered in magnitude by removing the rear damping and thereby threw my compensation off, thus leading to my perception that the frequency response change was too great.  However, I also felt the bass was a bit uncontrolled with a voltage source as well (ifi micro).

I do think that that the HD650 benefits from some boosting in the bass.  I have previously done this in my set-up by not fully-correcting the frequency response secondary to the elevated Zout of my source(s).  Lately, though, I have been correcting the impedance-related frequency response change fully (the impedance changes effect farther up the frequency range and perhaps don't extend low enough) and instead generating a curve to have the HD650 match the Harman curve in the bass (like Tyll).

My thoughts:
1.  I suspect the rear damping removal mod is doing acoustically what I have been doing electrically regarding damping the low frequency diaphragm resonance
2.  I stopped before doing the "coin mod" to the front foam as it wasn't reversible; this may have restored the balance/improved my perceptions, as:
3.  Detailed work on a Harman curve leads to a bit of a "smiley" EQ, the upper range of which I speculate may be somewhat similar to the "coin mod."
4.  I don't have the ability to take acoustic measurements and therefore all this is simply speculation; I would love to see frequency response and impedance magnitude measurements of un-modded and fully modded HD650s.
5.  While I can't fully eliminate all variables and therefore can't describe causation, there is something certainly appealing subjectively to current drive to me.
6.  Implementing a curve to fully achieve a Harman response is very, very interesting.

Best wishes,

Bill

I suspect the impedance did change with removal of the damping, although I haven't measured it. I know for a fact that the impedance peaks of voice coil drivers will change slightly depending on whether a driver is measured free-air or on a sealed plate / dummy head.

Impedance does slightly change. Tyll measured my pair. Overall differences are relatively small in all measured regards.

Interesting, thank you.

The back of the diaphragm is open into a short tube, the end of which is damped by three foam disks stacked on each other, these are the ones removed in the described modification.

Is there interest in me posting my Harman-style EQ curve?  If so, should I post my experimental results here as it is HD650-specific or in the Harman curve thread?

Got the balanced cable I ordered in the mail.  Guy made it from Mogami 2893 instead of 2534 but I'll forgive him.  2893 is thinner/more flexible and probably better for this application anyhow.  Cable is well wrapped, light and it seems like the connectors and reliefs are well done.

Going from SE to balanced on Ragnarok there really is an obvious jump.  On the 650 bass really tightens up, significantly closing the gap in bass performance between it and the LCD-3F.  Also, the soundstage, imaging and general feeling of "space" are significantly improved.  I don't think I will do too much A/B here because it was obvious in the first 10 seconds the balanced connection was better then the SE.

I've also finally acquired the parts to make my own balanced cable (OEM cable + Neutrik Gold) so sometime in the next week or two I'm going to fire up the soldering station at work and learn to solder... wish me luck!

Noob Question here and something I read in a post a while back but cannot remember what thread it was in.

I have a pretty simple setup as only my budget will allow at this time (JRiver MC21-->Bifrost Uber USB Gen2-->Valhalla 2 (Stock Tubes - but want Amperex Orange Globes)-->HD650

I have the mods done that were posted (cut the foam around the drivers and removed foam from back of drivers) - I really like the sound. I guess what my question is - Do headphones that are amped sound better louder? Do most of you listen to music rather loudly? Will the HD650 benefit from being cranked at high volumes? I am not sure what is a "normal" listening level, but I would say I am probably around the middle (not too loud, not too soft) if that makes sense  (I guess most people would say they listen not too loud, not too soft but I am not sure how else to put it).

It's a matter of perspective, but in general dynamics like the HD6xx/800 will sound more dynamic and lively as they get louder and have more power behind them. Stats on the other hand sound much more capable and engaging at lower volumes than said dynamics above.

My perspective is I enjoy to listen at live musical performance levels like up where or near the band is. That's my reference. Other's want loge A row 25 seat C or just to chill out with their tunes. All three preferences will sound different.

Whatever sounds best to you.  Also if you read some old post some members state that some amps are better at certain levels and some, usually the good ones  (though correlation not causation), keep their positive traits thought the volume range


Personally I just test at listening levels.  If its better at levels I can't listen at for too long  that doesn't help me. Though I will say that better mastered material can be turned up louder

Listening to The Who or Motorhead records at their live, over 120 decibel volumes would be insane. Most recordings are mixed at 80 to 90 something decibels and tracked even louder with compressors and limiters to not clip anything. The sound pressure levels where drum kits and high gain amps are miced can be ridiculous. Listening at at very low levels and using some headphone with a V shaped frequency response to approximate the 80-100 db equal volume contour of a human ear is inherently unnatural. That's not what the band would sound like playing at that volume and that's not what the recording sounds like at 60-70 db; you're just distorting the mix. No headphones are voiced to have a "neutral at 90db" response at 65 db conversation levels anyway; they would fall apart when cranked to the levels most recordings were mixed be to listened to at.

I think there is some truth in between this. My experience has been basically the following:

At lower levels, for most dynamics, the blackground is typically not truly black, so music will tend to sound more diffused/soft/flat/bland in a way. And this will only get worse as you go lower and lower in levels until you hit the noise floor, and then you'll only hear some soft, constant hum.

In contrast, for certain electrostatic/orthodynamic gears, the blackground is truly black, and so music will tend to retain good tonal and bandwidth contrast even at lower levels, thus giving them a more engaging sound.

As the volume is cranked up higher, though, electrostatic/orthodynamic drivers start sounding uneven, likely due to the movement of the diaphragm being not so uniform anymore (greater excursion is required for higher levels, and so that causes more strain on the diaphragm in general), and thus they start sounding... weird. What was once pleasing tonal contrast quickly spotlights these "problems", and the resulting sonic experience is no longer pleasing. More and more "control" is necessary for these types of headphones, but I think there are still some physical limitations/issues/kinks that need to be overcome/resolved/worked out before these techs can truly be good.

In comparison, dynamics don't tend to spotlight issues, and may even "hide" these issues somewhat, again, at the expense of true blackground. But at higher levels, the contrast between the noise floor and music gets bigger, and so whether the blackground is truly black or not probably doesn't matter anymore, and the increased tonal contrast/bandwidth is a very welcome change compared to at lower levels.

So in short, I think it's true that dynamics sound better and better as they are amped/cranked up, but it may not be the case with electrostatic/orthodynamic headphones. There are some exceptions to this rule, but typically, I find ortho/e-stat not very pleasing at high listening levels (>80dB).

No kidding. I won't even do that a live concert as I'll have IEMs or plugs with me. Thank goodness the performance of live unamplified instruments don't avg. 120dB. I think the avg. would be around 75-85dB depending on the specifics.

Sometimes I wish the HD 650 had more air for shelved, frequency masked, or less forwardly miced cymbals. Occasionally I wish snares were more cutting, put on a Beyer for a few seconds, and then quickly put the HD 650 back on as Beyer.
