Earpads only. Genuine part, taken from Sennheiser HD 350BT / HD 450BT headphones (identical part).
I believe it is also compatible with Sennheiser HD 4.50BT, HD 4.50, HD 4.50BTNC, HD 4.50SE, HD 4.40BT, HD 4.30G, HD 4.20S, HD 458BT, HD 450, HD 450BT, HD 400S, HD 350BT, HD300 headphones.
Taken from a used set. Minor marks. Still in good condition with plenty of life left.
