Interesting, the wooliness of the bass sounds quite diminished by this too.

Not completely gone, at least not when A/Bed against my HE400. But it is a noticible improvement compared to before. The specific segment I test this with is what Marv noted in the HE500 wooliness thread (the beginning section of 'If I Were You' by K.D. Lang). In my other usual bassy test tracks that improvement does propagate too.



How would this play with the Audeze cans?  The grill over the magnetic structure is much more simple compared to the hifman line.  The new fazor damping/diffusers in the new X line seem to be exactly what this is, but the old LCD2 and LCD3 don't have them.
Audeze's magnet retaining assembly grill is functionally identical to Hifiman's, really. It's just that the driver design of HE4/5/5LE/500/6 try to utilize as much of the membrane surface area as possible for conductor tracings, while Audeze opts to only use a central rectangular area of the circular membrane for the tracings. Abyss' driver design is like Audeze's in that respect.

All it means is you need a different damping cutout for HFM drivers compared to Audeze/Abyss's.

Actually, I figured that was going to be your next step since we had been discussing the fazor stuff.

What would be nice is if a handy cutout or cookie stamp (on Creatology foam, etc.) can be made to mass produce the item.

My wife uses this cutter for her crafts.  It's insanely good at what it does, and cutting stuff like creatology foam is exactly what it does well.  The layout is super easy in the supplied software.

Not that I've confirmed I like the Anax mod in my HD-800 I'm going to cut them properly using the Silhouette.  All you need is the dimensions.  Once you have the drawings right, you could rip out duplicates pretty quickly, and maximize the amount of pieces per sheet as well.

Not cheap, so not likely you want one unless you have some uses for it.  One nice thing about it is you can drop a pen in place of the cutting knife and use it as a plotter.  I've been laying out my chassis stuff on this now.  It's a surprisingly good and quite capable machine.

Yeah, well, you know, that's just, like, your opinion, man.

Good idea on that mod! I've got a lot of spare Creatology foam around, haha, so I'll give it a shot. Hopefully it isn't too thick.

I've also considered applying foam to the tiny bit of bare plastic on the inside of the cups (back side). I doubt it would make a big difference, but it makes for one less reflective area.

I don't think that's too relevant, mainly because of the angle. Whatever reflects off of it from the drivers is going out the backside anyway.

Any thoughts on Creatology foam (also have a ton of spare) vs. felt?  Felt would seem to be slightly more "absorbtive" than the foam.

I used both materials sandwiched together in the Abyss mod.

Hi.
This is my first post so I want to say hello to everyone.
I have hifiman he-500 phones (driven by rotel rb 1080 amplifier) and I was curious if someone tried to attatched stock velour pads to those phones just like audeze (with ring of 3m duoble sided tape)?

It will be interesting to see what will change if those phones would have better seal (with even less sound leakage than stock pads)- completely opposite to jerg mods.

There is no seal if you use velour pads lol. The velour is completely leaky.

You are right but there is also a leak from back of pad (there is a slight space beetween pad and headphone so one can easly twist them- some sound can leak from that side too). Anyway I glued mine and I can say that sound is more analitical with less bass. So now they are less musical but faster.
First I glued only one channel to compare it to other side (I used singen 2.1). Bass was different (less bass in glued side but also sound of bass was different). Then I glued other side and listen to music.
I was wondering how it might look on the graph. Maybe I'll try it with pleathers too.

If you consult my Jergpad mod on Head-fi, you'll see that I opt to have double-sided tape adhered to the mounting rings rather than the pads, thus it still ends up having full pad-cup contact despite the plastic mounting rings sandwiched in-between.

I didn't do that for the sake of seal though, in fact IMO HE500 sounds best without full seal, at least with stock Hifiman earpads. Most of HE500's frequency response is damped well enough by air.
