Not to bring back a dead thread, but I never saw all of these responses.
As for pictures, I'm still "trying", (I've been lazy I'll admit,) but I am actually getting on that now.
Prune: The density of the foam that's sent in the free sample pack seems pretty low, maybe less than the matresses. It's really not bad for this rather odd application.
TeRrAPh0eNiX: Go for it, it's worth a try. Even if for nothing other than to say you have Tempur-Pedic headphone pads, because that, let me tell you, is fun.
Strohmie: Not too sure it's what you meant, but your post made me replicate (well, try to replicate) the slits around the hole that the flat pads have. Seems to have made a slight change for the better. Upper mids to highs are slightly clearer, and the muffled sound has lifted a little bit. The bass still needs EQing to sound acceptable, and I'd still like the muffle to leave entirely, but I'll sacrifice a few things for the comfort.
Was ist los?: That won't be neccesary, since not too long ago, I did actually pad the headband, using some fake fur I found in my basement. Kind of funny looking, but very comfortable. I figure that if I'm going to wear headphones that look a little bit odd anyway, I may as well just go for broke.
