The NEW JVC HA-S400. Affordable Carbon Nanotube cans for the masses.

I recently bought the S400s and, while I really enjoy their sound, I find them kind of uncomfortable as they squeeze my ear against my glasses.  What's the best choice here?  Are there ear pads that are perhaps softer that would resolve it or is there some other thing I can do to make them more comfortable?  I don't have any problems with them on my ears themselves or my head, just that part where they squeeze against my glasses.  If I take off my glasses they're fine, but I do like being able to see...

I have the same problem, what I normally do is stretch out the headband over a stack of books about the size of the width of your head, and leave them for several hours or overnight.  Afterwards they will clamp less on the ears and glasses, however you will have to stretch them out on a regular basis when you are not using them as the headband will return to the original clamping pressure after a day or so.

I'll try it out. I suppose time will help the issue since my noggin won't be shrinking any time soon.

I usually just slide the glasses' arms up over the top of the pads...and not just with the JVC's.

The headband hinge broke on my Ha-sz2000's, the hinges on these look identical but I feel like they're smaller.  Can anyone confirm whether they are the same?  If they are I'll buy a pair and salvage for parts.

It seems like the hype on these has long since fizzled, but I bought the black ones anyway, if for no other reason than as a case study in headphone hype. :smirk:

Hello head-fi'ers! I'm new here. Just got a beyerdynamic dtx 910 today with a fiio a1 amp. Seeing this thread after placing the order. I was wondering if. I'm in India and the s400 is barely 10$ more than what I spent for the beyer. Do you think I should switch? I bought from Amazon. I do realise that both are world's apart, the beyer being open back and the jvc being closed. But still. Will the gain in Quality be that good? I'm pretty satisfied with the purchase except the build which feels pretty flimsy. Do reply. Please do excuse my noobness( if there is such a term :p)
Cheers.

Welcome, @AgentVJK ... :)
 
I'm hoping someone else can here can speak more specifically to your question about the S400 vs those new Beyerdynamic DTX 910 you just got.  I have the DT 880 Pro 250 Ohm and those are, at least to my ears, quite a bit better than the S400, but that's what I would also expect.  It looks like the DTX 910 are some of Beyer's more affordable cans, and I'm very curious about what you think of them...
 
...because, at least in my head, the question about "should you switch" from those DTX 910 to the S400 is, "are you happy with the Beyers and if so, why, and if not, why not? :) "
 
They are certainly very different headphones, not only open (DTX 910) vs closed (S400) but also size, over-ear (DTX 910) vs on-ear (S400).  
If comfort is important, I suspect, at least given my experience with over-ear headphones in general and with the DT 880 in particular, that the DTX 910 are much comfier than the S400 will be.
 
If, on the other hand, you want something a lot more portable, the S400 obviously have an advantage.

Thank you so much for the reply.
I've decided to return the dtx 910. I have to say out of the box they sounded really good with a very balanced sound. They especially sounded amazing with my Yamaha dd65 digital drum machine. But after putting about 15-20 hours on it I have to say the sound quality seems to be deteriorating. The soundstage has clearly widened but The bass which was nice and punchy has now become very muddy.also I have an average sized head but still getting these on takes quite a lot of adjustment even at the longest setting. To add to the horror , the plastic used in the extensions feels very, very ,very flimsy. I'm pretty disappointed and decided to return it. I can't really find any options other than the s400. If any , do enlighten me. Thanks a lot!

Cheers.

I just got a japanese import red one. Wow, this one sounds so different from the black/gold US text version I bought 4 years ago (that recently broke)... Also waaaaaaaay less clamp than that one.

The sound is bass light right now, and the mids and highs already have more definition to them than my old pair, which had well over 300 hours of burn in..

So it seems like the Japanese version of the S-400 sounds the most natural with the stock pads, and putting Shure 1540 Alcantara pads on makes the sound way too lean and bass light.

I have another broken (at the hinges) US version S-400 that's a lot bassier and lower mid heavy than the Japanese version, I have put the Shure Alcantara pads on them. I figured since they're that much warmer, the sound should balance out by putting on some over ear velour pads on them, AND increase the comfort by a lot.

Will report back after I've done some listening.
