Perhaps what you are hearing is simply the more extended high frequency response compared to what you are used to with your HE500 phones.  High frequency reproduction requires fast driver movement.

+1, the sooner the better!

It's something that can be retrofitted to the first batch and done on every next one so the sooner they know the more likely they'll do something about it.

I might contact Dr. Fang about it...seems like a minor design oversight that could be easily adjusted for a lot of improvement (especially for subbass-head customers, which seems to be about 80% of Head-fiers).

Contact! Contact! While the first batch is still in the works!

That's what I am thinking.. (!)

So much R&D and they can't seem to get these seemingly simple things right.

While I didn't feel the re-grilling mod did much of anything, these are things they also should've tried to improve, but instead were left just the same as before.

Hopefully some of these fixes will be utilized in the 400i from the get go.

They really should just hire Jerg...

Yes and no...
You can have speed without high frequency extension tongue.gif

No this is much more than that, I'm not just hearing more articulated high frequencies, but across the board most notably the midrange.

ALL ADD WEIGHT, to the cans...
I like the adhesive foam better, because it not only lighter,
But is an exact even layer to place, and so will not oooozzeee when squeezed.

^ I'd still love for it to be fixed rather than having to DIY... Not a big fan of that :P

@jerg - did you use the felt because that's what you had on hand, or did you choose it over the adhesive foam for a reason?  I've got thick and thin felt, and the foam.

I'm the opposite, these aren't significant enough to be "issues" (Hifiman headphones are still some of the most extended in terms of bass) so it's fun for me to try and improve it.

There is only enough space under the baffles for a layer of thick creatology felt, any more and you interfere with the properly screwing in the baffle screws. And the adhesive backing means nothing will ever shift or move in the long run.

No, absolutely, I get that, but it would be nice if they could do something about it if it's not too late.

So now I must assume it has superior bass over the others? (!)
Great news regardless as seems like a straight forward mod most can do..

It should now be a monster of a can overall

I already sent a PM to Fang describing what I found about the baffles. Chill out people.

Nah I'd say now it's about on par in extension to HE500s (that have not had this mod) now.

This, but has @jerg noticed any change to the overall signature; e.g., bleed into, or muffling of, neighboring frequencies?  I'm thinking of the bass port mod on the Q701s and how some people feel it affected the lower mids and soundstage (but most thinking it's worth doing in the end).

 

Just a little more coffee and footy, and I'll start tinkering :D

Me too I wonder which is better...
So try one cup felt and other cup foam.. Lol

This is not affecting seal in any way, shape, or form, unlike bass ports. I already thought it through before trying this yesterday whether it would affect anything else, and really there is felt already under the baffles, adding more felt just improves very low frequency conduction, nothing else. Only very low frequencies are conductive through material, anything over 50 Hz mostly propagates through air.
