I have a pair of Phiaton MS400's that I've had for a while. I know they're not the best out there but they're good enough for me and I'm pretty fond of them. They work fine but the earpads are disintegrating. I was hoping to find replacement earpads but I'm coming up with nothing. I know they weren't terribly popular so I guess I shouldn't be surprised. Do they make universal earpads and how would I go about figuring out which ones will fit?
