Shipsupt on head-fi has DT1350's and he's buddies with CEE TEE.  Maybe he can use his powers of persuasion.

Tyll's got an article up about the "Amperior" version of these which have machined aluminum cups which look like they might take care of some of those issues.

WTF! $350 for some "Emperor Fritz" version to fix a issue with the HD25-i-x-2334-123-i=2=ii? that should have been fixed on the original to begin with?

That's HALL OF SHAME!

....and probably still isnt really fixed. I thought the same thing.

I guess you don't think the aluminum cups are worth it then...

I'm sure it's worth something.  But according to Tyll, the HD25 was released in 1989.  So after 23 years, and a million roman numerals and dash signs and numbers, they..... remold the cups in a different material.  Fail.

Wowzers, machined aluminum rather than cast shells.  They are definitely making the case for the premium price.  Probably hard to justify charging double to mass dampen the stock plastic shells and add foam.  At least it's not as bad as what Ultrasone does.

i had no idea the hd25 was that old.

Oh yeah, and there's some story about the design being cobbled together from spare parts lying around when some Senn engineers were travelling and need some phones on the spot.

The drivers are different too.  They reduced the impedance and probably tweaked them a bit.  Don't know how much that counts for though.

They don't look to be that different because of how similar the SW looks.  I guess we'll see though...

really. sounds interesting. maybe that's why i never heard them then. i still don't understand after all these years it took them this long just to change the cups lol. sennheiser has bunch of geniuses running the creative department for the hd-25. i want to see their hd414 and hd424 brought back. they were some very interesting headphones using microphone drivers instead of your typical headphone drivers. but all i can do is dream.

Kind of a time to resurrect old topic, since Amperior seems to sell (on ebay) less than HD 25 it is interesting Question: Is Amperior better then HD 25 1 ii (whatever). looking at headroom and goldenear graphs it is evident that Amperior have more bloated 100-300 Hz while HD 25 stays more linear.

However people suggest opposite,- that Apmerior has more clean and punchy bass and less strident highs. I know it is hard to measure on ear headphones and graphs show more bass then it is in reality but I hardly believe that Amperior is better.

It is interesting to put p-leather pads on Amperior and see how it measures

thoughts? what you think is Amperior worse?

Amperior is more or less the same, except it tends to have better channel matching and better QC in general.
Plus metal shells, so its reverb sounds different.

Other than this, definitely not worth $300. If you need a closed supraaural, DT1350 can be had for the price - if you can find a good sounding one.
If not, Senn HD598 or Beyer DT880, depending on whether you want more bass or highs.

I agree, they are more or less the same cans but thing is - Amperior has more uneven response, and in critical listening you can reveal this flaw. I tried HD25 in the shop and liked it briefly, but I am not sure how it handles classical music. I need on ear good isolating cans for to use it in my workplace. currently I have Shure SRH 940 but they are large and have uncomfortable headband (which I changed) 

good thing with Amperior is that you can find it rather cheap then HD 25 1 ii, (on ebay) so I was thinking it is not worth to pay for Amperior now better buy would be old HD 25...


I already have HD598 and tried DT880 600ohm, and DT1350... Beyers never impress me,  but still I need to try DT880 on good amp

I think if I was in the market for a closed headphone for work (and didn't need it to double as a on-the-go portable) I'd grab a Paradox.  I hear the isolation is really good.

For some reason my amperior headband is significantly more comfortable than my HD25 headband. At first I thought it was the different pads, but even after switching them out it still felt different. I think my amperior headband is slightly narrower which distributes the pressure more evenly on my ears.

Fostex T50RP isolation is so-so, falls behind DT1350 noticeably. Paradox is a bit better due to more damping, but still lots behind. It's also not closed, it's vented.

If affordable and fun is your thing just get an AKG K81/518. It sounds like a HD25 without its shrill peak and very nice bass. Not a lot of detail though.

Otherwise the M50 is good enough to audition.

Probably I will try to modify myself Fostex T50RP, Paradox price is too high for me, if I take in account that some guy played with damping materials on these. I respect peoples work but it is more fun to try mod it yourself. Also Fostex based cans are large for using on road, bus or at work. I need on ears (can't use in ear) Anyway thanks for suggestions  :) :) :)

I see that there are some good sounding DT1350's but hell who knows which version will be shipped for you,  :-00 Total fail Beyer TOTAL, BTW my friend has them and I listened for a while and I thought I could go out now grab any 20$ can from next electronics store and I will have better phone :D
