  Did you find the dt1350's to be comfortable?

 
Yes, I did. Though looking back at my time with the DT1350, it was a well used pair (my friend's). The headband probably loosen up a bit and, other than being straight-cable, I don't quite remember which exact version it was.
 
And a bit of a tip for those who want to loosen up the Amperiors a bit, you could remove the top padding to reduce clamp. But... now you're exposed to bare hard slightly-rough plastic that might be uncomfortable depending how much hair you have up top.
 
I have two main configurations for the Amperior:
1.) no headband padding + vinyl pads
2.) Custom One Pro headband padding + velour pads

Interesting. I've been wearing the amperiors for hours now, and I'm fine with them. But the dt1350's were unbearable after an hour. I even tried stretching the headband but that didn't work for me. I guess everyone "feels differently"..

if your looking for a snug clamp, look no further then the focal spirit series (those are like vice grips ) though they isolate splendidly and they are supremely stable for over ear headphones (which at lot of the times can shuffle a bit
 
also the beats solo2 is snug too, though the have thicker earpads then the amperiors (but I tried two pairs next to each other in the apple store) one is pretty beat up (but it was quite comfortable) and a spanking new one, which had a tight clamp.
 
but Id rather have a tight clamp then loose (you can gradually loosen them, with books or just daily wear)
 
if their loose well... unless their headbands are ridiculously strong then your kinda stuck.
even with the vmoda xs (which has that strong headband) I couldn't get it to clamp any tighter... it was still quite loose on my head....
 
the amps are quite comfortable for me now (I think its been 1 year) woot 1 year anniversary =)
 
I'm using the amps with the pleather hd 25 earpads (just for a change of pace) the original velours are just sitting in my drawer) and the hd25 pads are nicely padded (their probably just newer then the velours that's why)

 

[RERO]

Yep, in some cases a strong clamp is beneficial. I remember when I accidentally tugged the cable and my Amperior almost fell on the tracks. This was when I was using the COP padding + HD25 pads. The pads already had less grip than the stock velours and the COP padding just made it worse. I had a few minor accidental slippage even prior to that event with the same setup. Thankfully, the aluminium bits are still unscathed till this day (1 year and almost 3 months of ownership

).

I think it's because of its size. They, DT1350 and T51p, don't rest much on my ear flaps compared to the HD25-series which, for me, requires to sit mostly on my ear flaps to sound optimally. It was a tough few days with the Amperiors.

Just bought into this little Amperior club. A local headphone specialist bought some overstocks from a Sennheiser disributor, so I got a really good deal on them - brand new virgin boxed.

I'd always wnated a pair, however by the time I got around to actively looking for them Sennheiser had stopped producing them, meaning they were nowhere to be found around here.

First impressions show that the treble is a bit more peaky than the HD25, but with more definition. In fact I'd say that they have a tad more definition overall than the HD25, but obvously with a very similar sound signature. I'll be looking to replace the velour pads with the artificial pleather pads of the HD25 as I find them more comfortable - yeah I'm weird

The icing on the cake was the in line iOS controls, however with the Amperior I think they're rather awkward, with the big fat cable from the headphones joining that rather thin cable to which the inline controls are attached. Nevertheless it's usable and better than nothing.

All in all I'm very happy to have this as a member of my headphone collection.

Oooh wanna trade those velours for my hd 25 pleathers?

If not wanna just sell em outright to me ??

Sennheiser Amperior way too harsh sounding (treble), hurts eardrums, hd 25-1 sounds VERY laidback in comparison

 
hi guys,
 
1. i have had these headphones for around 3 weeks now. When i listen to music on them, they pretty much hurt my eardrums (I think its the higher frequencies). Mind you, i should use the term "uncomfortable feeling", the pain is mild but will be there after using them for 30 minutes. I compared them to the hd 25-1 and this simply does not exist, when i listen to music my ears (eardrums) feel relaxed and i get that "lost in music" feeling, how ever when i listen with the amperiors i do not feel relaxed at all (eardrums), always some this sort of pressure/stress, the amperiors are softer on the ears but not for the eardrums. Its as if someone is shouting in the background during the music (i cant hear the shouts but i can feel the uncomfortableness). The is mainly felt with higher frequencies (vocals, piano note etc...), however throughout the whole song i get this uncomfortable sensation. When i switch back to the hd 25 everything feels relaxed again, no pressure, no high frequencies shouting at you , as if you just had a pee after you wake up and let go of all that pressure. The amperiors do not sound bad in any way, they sound excellent, just feels like the headphones shouts the music at you, makes is annoying/hurt), and it exists all the time. its not something that i have to take them off immediately for, but it builds up pretty fast. Is this common for the amperior? I feel they are way more V-shaped than the hd25, i feel as if the frequencies in the hd25 are much more balanced, giving music a much more smooth and pleasant sound, compared to the amperior, where i feel as if its a bit of a mess, each frequency demands its own attention, which is i think why i get that "lost in music" feeling when listening to the hd25, where the amperior sounds more all over the place. 
 
if it makes any difference the hd 25-1 are my brothers (they are currently not with me) and have existed for atleast 7 years, where as the amperiors are refurbs and i have had them for 3 weeks and used for around 50-70 hours. Out of these hours i have used them for maybe 10 hours, the rest is pink noise
 
2. Also, just something i wondered, but when i first got them, the vocals on tracks sounded very recessed (mids were quite recessed), as if they were veiled behind something, but now i can hear them quite upfront. Is this my ear getting used to it or do the headphones change upon usage (talking about burn in, im convinced it exists but the change is quite big, seems like only the brain can do such a vast change)? 
 
Just to make things clear, when i listen to these headphones, i do not feel pain as if something is directly hurting me. its more of the annoying pressure/sensation you get when someone talks too loudly next to your ear and it gets uncomfortable. I listened on the same volumes for different headphones (sennheiser cx300, hd25, marley xlbt and other headphones lying aorung the house) and this simply does not exist. Even when the volume is louder on those headphones i dont get this feeling. And these headphones still sound better than all of them.
 
thanks, and sorry for the long post.

No need to yell my friend!
 
Sorry they are hurting your ears. Although I don't have the greatest hearing in the upper echelons, my ears are fairly sensitive to bright or sibilant highs etc. I've had the amperiors for a few weeks now (they were used but in excellent condition), and I don't have any issues with the highs. In fact, the SQ of the amperiors is amazing to my ears. Possibly mine have been burned in and that helps? Or possibly we just hear differently?
 
Either way, I hope they end up working out better for you.

 

[Pedro Oliveira]

To me the hd25 always was a better headphone than the amperior in every way. Amperior sounds like a messed up hd25....it has more bass but its not as tight on the hd25, the mids are more recessed and the treble reduction along with the more recessed mids makes vocals sound a tiny bit muffled and because of this the amperior it not even near as adicting for more agressive rock. Listen to some biffy clyro or blink 182 and checkout the agressiveness and detail of the eletric guitars on the hd25 and on the amperior....
Maybe i had a bad amperior but from my experience i would take the hd25 any day. And yes i also thought (although none is very confortable) that the hds25s with the leatherette pads are more confortable than the amperiors and their stiff velour pads.

Had them both for almost a year at the same time and i always grabbed the hd25s first.

lol sorry for shouting i simply copy pasted my own thread together with its title, i got no replies so i posted here (a good thing i did!)
Im just not too sure what causes the pain, if its treble or not, but i will be burning them in for a lot long before i try them on again ( they are refurbs, so they might have had some use). They do sound very good, although i much prefer the tonal balance/signature of the hd 25-1, everything sounds much more even, smoother and the mids to me are better on the hd 25. They do sound very good though, i admit even though the highs pain me, they are better on the amperior, a sort of airiness to them too.

i agree, the hd25 are smoother, and their lows and mids feel much more lush, more definition. they might not have the highs of the amperior, but the mids make up for it. I feel as if there is more definition, more "meet" to the music, guitar strings feel fuller and the whole tone of these headphones feels more satisfying, the frequencies are in balance with each other, and the bass has that enveloping feel that i so like which the amperiors dont (they pack a punch though). I dont know why people say these headphones have subtle differences, to me they are completely different headphones, they share the some good qualities but not the same sound at all.
I also prefer the leatherette pads, They sit better on my ears although the velors are more comfortable and i prefer their touch (the velors are stiffer but after usage it loosens up). I honestly dont know why they recessed the mids on the amperior, They do make the vocals sound a bit in the background but after using them for sometime this went away (perhaps i got used to them), but with the hd25 the vocals sound more present and lush, something the amperiors dont have, they focus on the highs more (the amperiors). I feel there is more definition because of the hd25 lush mids.
imo the hd25 for my taste is better, although the amperior have good sq too  - highs are more defined here but i feel they just took the mids place, giving them a more vshape sound in comparissn to the hd25. 
I admit i need to spend more time to get used to these headphones (only used them for 14-16 hours), i must admit that on my first use and comparison of these headphones, these differences were very clear to me, i did not have to try and see the differences, these were obviously different headphones. I had used the amperiors brefore i tried on the hd25 (they are my brothers, he let me use them for a few days).

 

[RERO]

 

if it makes any difference the hd 25-1 are my brothers (they are currently not with me) and have existed for atleast 7 years

 
Perhaps that might be the problem. His HD25 might have gone through a lot that the drivers have tamed a bit.
 
Have you tried using the same pads on both of them?
 
Perhaps try to setup a blind ABX test with the same pads. It shouldn't be that hard to eliminate physical bias between those two considering they're almost identical.

thanks, and sorry for the long post.

no problems for the long post my friend! 
 
thanks for being so thorough when explaining! it helps other posters/reader to better understand what your saying by providing a better context to your inquiry!
 
anyways 
 
i find the biggest problem with your assessment of the amperiors vs the hd25 is what i bolded above.
 
and here is my reasoning for that 
 
take a look here: These are the specs for the hd25-1- ii (assuming you have this one ofc)       

THD, total harmonic distortion	< 0,3 %
Contact pressure	~ 2,5 N
Ear coupling	supraaural
Jack plug	3,5/6,3 mm stereo
Cable length	1,5 m
Transducer principle	dynamic, closed
Weight	Without cable: ~ 140 g
Nominal impedance	70 Ω
Load rating	200 mW
Max. Sound pressure level (active)	120 dB

     and take a lookie here on the amperiors  ( i couldn't find them on the sennheiser website but i have my personal amperiors here with me with the box 
 

THD, total harmonic distortion	< 0,3 %
Contact pressure	b/a
Ear coupling	supraaural
Jack plug
Cable length
Transducer principle	dynamic, closed
Weight
Nominal impedance	18 Ω
Load rating	????
Max. Sound pressure level (active)	120 dB

 
its obviously not complete but here is a link to it (not sure how credible this is) but click on the impedance compared  for me anyway it shows the sennheiser hd 25 (alu) which supposedly have the same drivers as the HD25 but with the aluminum earcups (not sure if they are acoustically identical to the amperiors
 
but you can see in that graph the impedance is much lower 
 
and if you assume they have the same spl which is what we see here..... it should tell you that the amperiors are more efficient > the hd25 = it requires less Voltage and power, essentially to drive the amperiors > the hd 25
 
so if you compared them at the same volume, then the amperiors would naturally be "louder" 
 
 
also i haven't heard the cx 300 II (but i have heard their successors the cx 3.00) which i found quite warm and dark sounding (somewhat treble-deficient) so they would sound much much smoother and easier then the amperiors if they were given the same volume and voltage essentially
 
so essentially you can't exactly compare the hd25 and the amperiors directly based on "volume" even if the same song and device and such. 
 
but lastly like you said even after all of that, the amperiors aren't comfortable to you and you still find the hd25 more to your liking, whether its due to your listening volume, genre preference or your current equipment.
 
just go for the hd25, or if anything take them from your brother and buy him a new one!

Hi tom,
Im aware of the impedence on both headphones and i took that into account. even on higher volumes the hd25 felt more comfortable. Then again, now that i think about it the hd25 might feel louder to me due to the mids being less recessed, which is what im usually focusing on. They just didnt pierce my ears like the amperior, even on high volume levels. I ffelt they were less sibilant too. Maybe the lack of mids on the amperiors make me turn up the volume more to hear the mids but as a result the highs become to overbearing. My brothers certainly did not have issues with these headphones, only me, so maybe im sensitive to treble

I just find it hard to give up on the mids, the guitars for example dont have that full "twaaang" sound, not sure what is the correct word for that. Vocals feel more present and up close (on the hd25) i have always had a preference for the mids, maybe because most of my life i have used rather cheap sennheiser iem <30$ that have made the mids the main focus, which is why i need to get accustomed the the amperiors more

 

[waynes world]

I'm not familiar with the hd25's, but the mids on my amperiors more forward than recessed to me.. they shine right on through beautifully.

 

[myemaildw]

may be it is ressesed mids i dont know. its sounds good but if you are sensitive to them and dont like on ear pressure of these its all a bit pointless. they sound fantastic though. even lachlan said that for some people amperiors are a bit too much. what he meant by that i dont know, he didnt explain. if you want to know where he said that its in his patreon, its for pledgers only. but i suppose it relates to that some people are sensitive to its sound. cheers
