OPPO PM-2’s earpads are mounted on rubber inserts that can be easily cleaned or replaced. This design makes it easy to try out PM-1’s lambskin and velour earpads. The headphone cable is detachable and uses 2.5 mm mono mini jacks to connect to the earcups, 6.35 mm terminated cable for home use, and a shorter, 3.5 mm terminated cable for portable use.
