Title: My dt250-250 and beyer inconsistencies
Post by: donunus on September 14, 2012, 11:16:17 AM
I love my 250 ohm dt250. They are probably the most musical sounding headphone I have heard to date regardless of price. When I say musical, it means a good combination of liveliness, punch, accuracy and dynamics but they have their weaknessess and for less than 200 US dollars i am willing to accept them since I think they sound better out of a basic O2 amp than the he6 out of a speaker amp via speaker terminals.

The dt250-250 ohm sounds like the hd600 combined with the hd650 with just a slight touch of extra presence/transient response while being a closed design at the same time. This is such a great feat in my book since I have never heard such a sound from any closed design ever. These closed cans have never ever made me feel the usual closed headphone honkiness that is present in every other closed headphone I have ever heard. In fact, this is the first time I have ever listened to headphones that have made me happy with every piece of music I own ever since I've owned them. I usually only own headphones for a month max unless they are good but for the first time I kept something for quite a while besides the hd600 which I also owned many times. I felt in the end the dt250-250 was the better alrounder though making the hd600 and 650 only second and third in my allrounder book.

Now whats this about inconsistencies? Well Beyer has had a record of differences within the same model like the dt1350 measurements on this site. I've heard about differences between other beyer models too but I wanted to test this myself so i contacted Beyer via facebook. I asked that they replace my dt250-250 that distorted on the right channel before the left using this test here http://www.audiocheck.net/Audio/audiocheck.net_headphoneshaker.mp3 then they gave me a brand new dt250-250 to replace the one i had. Awesome service on their part too since they covered shipping and customs taxes without even asking where I bought my cans from but the new ones still failed the test. The new ones had different inconsistencies from the right and left channels pre-burn in but still they sounded awesome like the first one.

The moral of the story is that I still love the 250 ohm version of the DT250 despite their slight differences from pair to pair. Highly recommended headphones that everyone should have  :)p13

PS: I've also owned the 80 ohm version at the same time and despite what other websites say... they sound much more bloated and less revealing than the 250 ohm versions.

You probably expect me to say this already, but the HE6 is a bit picky with amplification and thats probably why it sounded too bright.  :)p13

I hope to hear your DT250 sometime though! Too bad about the driver problems.

OK. Good to know the 250 is the one to get. It's still on my list.

Talking about inconsistencies, I'm not sure if its just due to the newer unwashed pads but after listening to a few albums on my second pair (ser# 70050) (Third counting the 80ohm version), I can say that these are better to me than my older pair (ser#63487). The highs on these newer ones just seem to have more presence and air beyond 10khz and the slight glare in the upper mids (around 2khz) that I found when using them with windows is not there anymore. I used to only get this sound when listening to music on them via Linux Ubuntu. One recording where I notice this upper midrange brightness is on Megadeth's "Countdown to Extinction". I used to always prefer the softer and warmer sounding 2004 remaster with the older 250 ohm version I had because the 1991 pressing had a nasal midrange glare that made me automatically choose the 2004 remaster. When using the newer cans, the 1991 pressing is still bright and trebley 10khz and up but the midrange nasality that annoyed me is gone, wow I am luvin it! I know this just shows more negativity about the beyer inconsistencies but damn the dt250-250s are cans I always enjoy regardless of the slight differences between the two 250 ohm models I've owned. In the overall grand scheme of things, they should all be perfect and have all the goodies that these cans can provide but since it is not a perfect world, I am happy with this newer airier one that I have without the extra midrange glare which I already thought was a very small tradeoff being maybe only 2 to 3db different than these in my estimation.

Yes, Beyerdynamic still continues the saga of pair to pair variance. I've just heard another T70p (SN02xxx) and I know what purrin meant. These older model sounded much brighter with more resonance.

Whoever manufactures Tesla drivers is onto them. Classic line are much less affected, but the cheaper ones like DT 231 and DT 250-250 are probably made at the same place as Tesla-based.
I've also checked a new DT 231 vs my 6 years old DT 231 - world of difference. Old one was bright with massive subbass loss - new one has reasonable subbass and isn't as ultrabright, but has noticeable midrange resonances.

Are they switching chinese driver manufacturers or something?

Just to add a little bit of further knowledge to this thread - I've had a DT250-250 that eventually developed a bass inconsistency between channels and I sent this pair to Beyer to be tested. They measured them and discovered that the flimsy cable (uh, my term, not theirs ;) ) in the headband was to blame for the uneven response. They replaced the entire headband and the cable and the pair once again sounded balanced. This experience indicates to me that the cable might be responsible for a lot of the pair variance issues we see with these headphones.

With all this said, as much as I liked the DT250-250, I decided that the uncertainty whether they are functioning properly is just too much of a hassle and I've moved on to other cans.

Post by: donunus on November 08, 2012, 10:10:41 AM
Beyers service is top notch though and if the replacement pair sounds balanced then it is a good one. I am loving mine. Going to other headphones is not an option unless one is willing to spend more because theres nothing better at this price range IMO.

I agree, the DT250-250 is probably the best headphone for the price provided you get a good pair. Their sole sore point for me (besides the technical issues) is the comfort (pads aren't completely circumaural for me) and the fact that they don't fold. Obviously, the latter two issues are very subjective and dependant on the user's needs and head/ear size.

With this said, I have to say I loved the Audio Technica ATH-M50 that I moved onto after the DT250. I also tried some KRK 8400's but really hated them - they were piercing and the bass was weird, sounded like someone farting :) I've been looking for an all-rounder closed-back circumaural monitor for years to use for work (I'm a film maker and video editor) and for pleasure and have tried pretty much every notable can below the 600$ range, with the exception of German Maestro/Charter Oak. Hated all Ultrasones due to their harshness, thought the MDR-7506 had a very annoying tonality for music listening (decent for voice tracking though, no wonder they're used so commonly in broadcasting). Sennheiser HD280 was uncomfortable and its bass was not neutral, lower-end Shures and Koss ProDJ100 were OK but not refined enough for my needs, higher end Shures also sounded fine but were too uncomfortable to honestly consider them as a work headphone. DT48 was really not for me, haven't heard the supposedly more neutral DT48A though. DT770 had waaay too much bass to be neutral. Closed-back AKG monitors on the other hand had too much of a bass roll-off to be used for work - it is good to have a headphone with decent sub-bass extension when trying to denoise and clean field recordings. M-Audio Q40 also had a lot of bass but wasn't so bad, sadly it was not very refined in the mids and treble, once again making them not ideal as a monitor. Fostex T50RP was quite nice stock but holy shit are they butt-ugly... I know looks are secondary to sound quality but I had to draw a line somewhere :) Denon, Allen & Heath and Pioneer DJ cans were just that - DJ cans - not tuned or suitable for production work in video or music that is not electronica. Sennheiser HD25-1 II (or something) was quite nice but not comfortable for me for longer sessions due to their supraaural design - a monitor IMO really needs to be circumaural. The same can be said about the Beyerdynamic DT1350. Hmm, I'm not sure if I forgot to mention anything but I certainly have gone to some lengths to track down the elusive all-rounder monitor out there...

So far, the best closed-back circumaural monitors that I have tried were definitely the DT250-250 but also the Audio Technica ATH-M50, which is receiving a lot of hate these days and I really don't understand why. The M50's V-shaped curve is actually a blessing both for work and for pleasure - at lower listening levels, they sound neutral (due to Munson-Fletcher curve) and for fun, I could listen to them louder and enjoy the emphasized bass and treble for a fun, punchy sound.

Finally, I have settled on the AKG K550 as it has a neutral sound, some mid emphasis (useful, once again, for voice tracking and other video work), do not have very rolled-off bass and are more refined than the DT250 or the ATH-M50. I did not really experience the glare that people are complaining about although they can sometimes get fatiguing. I am pretty happy so far but naturally, if something better comes along, I'll be more than happy to check it out :)

Post by: donunus on November 08, 2012, 10:03:53 PM
I myself didn't like the m50 either. I found them to have recessed mids and sharp highs. I hear that the sound changed a little since they first came out so that is a factor I don't know about. The K550 I still haven't heard. Those are also supposedly inconsistent from pair to pair.

Indeed, the white box version that is on sale now is more neutral than the classic M50.

I placed an order, we'll see what happens popcorn

Although the last time I tried to order a cheap out-of-stock item they eventually cancelled it, stating they Amazon wasn't selling the item anymore... Which was indeed true, but only for a month, then they started selling it again (at close to MSRP, of course).

You may want to look into the K267 Tiesto. Supposedly a much better sounding headphone than the K550, without the ringing and treble issues. The bass response is adjustable, and the adjustment apparently is much more effective than the Beyer Custom One according to Tyll.

I just bought a $28 250-250 also. I've been wanting to try them for awhile, and at that price you kinda have to.

In order for me to see the price, I have to click on the 250/250 headphone and then click on the "New From: $27". The page itself lists the price at $184. Then again, I'm in the US.

At such a low price, more than one could be measured to test any inconsistencies. But I suspect the low price is probably an error, like showing the price of the ear pads instead of the actual headphones.

The DT250-250 is in. I am now listening to Burial's album "Untrue" to get a good impression.

First impression: with its a closed and compact construction the DT250 sounds surprisingly open; the sound signature of this headphone is nearly perfect for someone used to a K500 and speakers in general; this headphone is revealing without attacking your ears with brightness and nasty peaks; not too smooth and not too in-your-face!, just right.

More updates later... 
Title: Re: My dt250-250 and beyer inconsistencies
Post by: donunus on October 29, 2013, 03:38:42 PM
I told you so :) the biggest gripe I have about them is the somewhat compressed dynamics and the slight lack of deep bass and some impact. These are small gripes though because I haven't heard a closed headphone yet at their price level that sounds as honest as these guys. I havent heard all the latest stuff though but I think you now know what I mean.
Title: Re: My dt250-250 and beyer inconsistencies
Post by: donunus on October 29, 2013, 03:52:35 PM
And about the soundstage... these sound just about right for a closed headphone. Not too wide/fake and just a good enough tonality to make you think that it has a little speakerlike depth. For comparisons sake... with the hd600s for example the sound is wider but don't give as much of a good impression of depth. These have a tonality that gives an impression of depth in between an HD600 and the hd595. I don't believe in headphone soundstage TOO much by the way. What I mean by that is that I believe that the soundstage on cans is the impression of width and depth influenced more by FR than time delays and reflections that affect speaker soundstage more for example.
Title: Re: My dt250-250 and beyer inconsistencies
Post by: Deep Funk on October 29, 2013, 04:00:46 PM
The DT250-250 is very sensitive from the headphone out, more so than my K500.

About bass, the amplifier makes a difference. From DT48's to my K400, a strong amplifier with clean signal and the right gain settings makes the difference.

The small dual mono amp that also drives my K500 gives the DT250 ample of juice and the Psy-Trance I am listening to does not sound shy of bass and impact. My portable K181 is sometimes too bassy for my preferences but it is a compromise I can live with. The K181 has a 'fatter' bass sound but less control. The DT250 goes low with control and the impact the K500 lacks = this is good   p:3

The DT250-250 is a keeper. 

Edit: if you want sound-stage get open headphones or speakers; if you want an open sound just hope the manufacturer did his homework.

Post by: Sforza on October 30, 2013, 06:55:51 AM
I've had the DT250-250 for a while now, my impressions on them are similar to Don's, with a few key differences. For all their strengths, I don't think they do deep bass at all. The bass seems to reach the mid bass, and then roll off gradually. For almost all types of music except for EDM, this isn't a problem at all. I often feel that the bass is lacking for electronic genres, even when compared to HD580 (with new pads). On the other hand, when listening to good jazz or rock recordings I feel that the bass is absolutely spot on. The treble is also rolled off a bit, but this then this makes them sound both sufficiently detailed and never too piercing.

With regard to openness and soundstage, they're really good for a closed headphone. I'm not really picky with closed headphones, as long as the sound isn't projected to the extreme left and right they're fine. I think that their depth might have been improved by the bass roll-off. These would make excellent monitors.

On a related note, I personally find them a bit boring, but nowhere near as blah as the SRH940. I could live with the DT250-250 as my only headphone.

hahaha yes. The k500 is quite hard to drive.

The dt250-250 is just about the same as the hd600 so far as sensitivity is concerned. There is a small difference but I forgot which one was slightly louder at the same level setting on the volume knob.

I agree. We just said it in a different way. It reaches down to 20hz with a good enough clarity but the volume at that frequency is already pretty low vs the 100hz area. So its a gradual rolloff but theres a signal there unlike some open cans where the same frequency sweep tests will only give some little popping noises and farts at that frequency :)

By the way, Beyer is weird with these cans in that they promised Tyll that he would get a review sample ages ago and it never happened. Maybe they don't want someone popular enough like Tyll saying that these demolish the T1s and the other teslas. They would be screwing themselves  :spank:

By listening alone, they sound like they would also have great CSD measurements. They are pretty quiet and dry... none of the seashell echo effect like open akgs making them have that grayish tone. They are more like senns without the extra full mids that create the illusion of too much width. I think of them as somewhat of an hd600 sound minus some of the senn butter(not too much) then add what a typical crossfeed filter (think meier) does to the "tonality". I said tonality because I don't want to give the impression that they have built in xfeed LOL

Great thing though is that even for just a regular consumer like me that lives outside the US, they still give great service. I got a replacement without too much of a hassle for proof of purchase, etc... I just contacted them via facebook and everything went smooth from then on. They even paid for all the shipping.

Despite the 250 ohm specification the seems to be easier to drive than my K181 from my old iRiver H10. My iRiver H10 has a fairly powerful headphone out. I am surprised by the efficiency of the DT250-250.

On sound: the DT250 is most definitely a proper studio headphone. Miles Davis' 1997 remaster of "Kind of Blue" not only sounds smooth and dynamic but also the noise in the intro is very much audible...

I see the Beyer DT250-250 measurements are now up on Innerfidelity. The square wave readings look quite a bit better (bass seems straighter/stronger) than the ones on HeadRoom.

http://www.headphone.com/learning-center/build-a-graph.php?graphID%5B0%5D=223&graphID%5B1%5D=&graphID%5B2%5D=&graphID%5B3%5D=&scale=30&graphType=3&buttonSelection=Update+Graph

^The bass square wave bows down a bit and also the "zero" point seems to be off. Bass extension (or the seal? but that seems quite consistent in the raw readings) seems quite a bit better on the Innerfidelity pair.

Wow, they measure pretty good for an old headphone. Now I wonder how they stack up against Tylls new favorite closed can... the NAD hp50. Tyll? Any thoughts? Or are the NADs much better overall?

Post by: Solderdude on November 10, 2013, 12:34:58 PM
hmm a good 4dB level difference between L and R from 300Hz to 2kHz (Tyll's version).
20Hz = -2dB  drop off above 10kHz

And to think that some people are bothered by a 0.1dB channel imbalance from an amplifier  :-Z.

the GE measurement seems to differ a lot  (I know...) no channel imbalance there.
http://en.goldenears.net/10680
20Hz= 0dB drop off above 10kHz

The Russian guys also had a better looking FR

BUT quite some differences between L and R also in the range of 4 to 5 dB which is (should be) more than obvious.
20Hz = -10dB no drop-off above 10kHz (a peak is even visible)

The Headroom plot looks a bit suspect .... roll-off in the lows starting from 100Hz and in the highs from 10kHz onwards ?
What's with that ? 20Hz = -15dB drop-off above 10kHz

I think the title of this thread thread is right on the money.... inconsistencies all over the place (channel imbalance) and or measurement/compensation errors.

^ That is why I had my first pair replaced. The inconsistency was more around the upper bass region on mine.

HeadRoom and goldenears.net show the 80 Ω version (the former incorrectly labels it as 250, but it can be seen on the impedance graph that it is really 80). That may or may not be responsible for some differences.

The odd thing about the pair tested at InnerFidelity is that it has decent matching in the bass and treble range, where balance problems are otherwise more common.

Some of the old HeadRoom/InnerFidelity graphs do show incorrect bass response (such as too much roll-off, or a large notch somewhere between 50 and 100 Hz), due to seal problems and resonance in the HATS. These have been fixed since then.

missed the 80 Ω part.  :-[

That accounts for the roll-off in the highs I reckon.

This is the 80 Ω version measured by the Russians and also shows a roll-off in the highs.
The 250 Ω version measures better aside from the channel imbalance which is better on the 80 Ω version.

Wow, they measure pretty good for an old headphone. Now I wonder how they stack up against Tylls new favorite closed can... the NAD hp50. Tyll? Any thoughts? Or are the NADs much better overall?

I'm not Tyll but I own both the HP50 and DT250-250 now. The main difference is in the bass region, the HP50 seems to be more detailed and the bass goes deeper. It also gives a wider sense of space, so the imaging is better. Other than that I feel like both headphones are very similar. Will add more impressions when I get used to how the NAD sounds.

Just got Sforza's NAD's here and I feel the dt250-250s to be the better headphone overall by memory. The NAD is still nice and I still highly prefer them to the momentums.

I am considering to replace the K181 with the DT250-250.

Is there a good case to transport the DT250 in that survives backpack abuse you can recommend?
Title: Re: My dt250-250 and beyer inconsistencies
Post by: donunus on November 27, 2013, 08:45:46 AM
there should be a bunch of stuff on ebay that would work. I'm sure if you can't find something specifically for the dt250 that you can fit them in anything made for grados.

I'm not associated with this seller in any way but I bought the case and some earpads from him and they are very good. Earpads are not genuine but very high quality.

The pads I bought were for a different headphone, just from the same seller. I was transplanting Koss PortaPro drivers into a KOSS 4AAAT enclosure and I replaced the vinyl pads of that headphone with velour pads for an AKG K240. Resulting headphone is really good, one of my favorite 'fun' headphones (good punchy sound but not too resolving).

You can buy cases of different sizes from him, so just measure your DT250 and buy the appropriate case...

Beyerdynamic 250/250 drivers in wood. Stock Beyer velour pads, Brainwavz HM5 headband. Cups have some very minor open-cell foam damping and had to be hermetically sealed (no venting) to obtain best results.

Very nice sounding.

Very nice, as always. Did you encounter channel matching issues? How much were the drivers?

I had an old 250 lying around, so I used those drivers. During the modding process I killed one of the drivers, so I had to order a replacement. I was quite pleasantly surprised that this driver did not have any significant variance from the old one. The replacement wasn't cheap, though, about $80 shipped.

Impressive, I never expected the DT250-250 to be woodied.

Is there an audible improvement worth mentioning?

I don't understand why Tyll hasn't reviewed his pair yet. I really think these cans are still better than most closed cans in its price range until today.

Tyll activities entail more than just Innerfidelity. He is lucky enough to sustain himself with his hobby but at the same time I cannot imagine him to ever have a proper vacation. (Unless he plans ahead most of the time, which I assume he does.)

He must receive several requests a day given he is regarded as a reliable and very competent reviewer.

At least he already measured the DT250-250.

Since the stock version does not really have any serious deficiencies, it is mostly aesthetic.
