eh... the pleather isn't bad unless it gets hot...or ppl start throwing stuff at you in order to get your attention

.
I finally got a reply back from sennheiser about the hd570 pads. Unfortunately, the only useful info I got was that they are the exact same size as the hd590. Then the guy linked me to the parts store and said that they are made for the hd570 so there is no need to measure them

. *duh* as if i would've emailed them for that.
So I replied explaining that I was hoping to get the measurements so I could see if they will fit any other headphones. That was tuesday I think. No reply yet, I may just have to send sennheiser a third request for help.
I wonder if they wouldn't like it if I told them I was looking for replacements for other HP's and I don't have the hd570's. *without mentioning they are AT's of course lol* I don't know why they would care really, they're selling something anyway.
Oh, and milkweg I would try calling AT or emailing them. Like opticelement said they don't sell the pads on the website, but they probably still have them.
Actually all things considered, the m50 do have good quality pleather at least, its nice, thick, and leather-like, unlike most cheap thin plastic stuff.
