I've been hesitating to buy a second set of earpads for my silver APM, but I decided that I needed to because I'm sick of washing the white earpads every week. When I searched for the black ones on Amazon I came across these knock offs. They were cheaper, but not by as much as I'd expect ($50 vs $69), but curiosity as to how they'd compare won the day. They were shipped straight from China, and honestly I'm impressed. They fit and feel just like the authentic pads for the most part and I can't hear any difference in audio quality.
