BTW, the Beyer pads are sold on Amazon. There's velour silver, velour black and leather black.
I wonder about the difference between the 770 velour pads and the GM velour pads though. I thought someone (maybe Acix) told that the GM velour pads thin out the sound compared to, say, the oval pads (41-6050).
And by the way, has anyone tried the stretch foam pads by GM (41-6015)? I got half a mind to get them but then again they're suspiciously cheap and they look like they might be too shallow.
