This is a set of SENNHEISER MOMENTUM4 Wireless (White) and ear pad covers. Accessories include what's shown in the photos and EarProfit multi 2 (worth 4000 yen)! I've used it for about a year after purchase. There are no noticeable scratches or stains, but there is some minor wear and tear from use. Operation has been confirmed. I don't feel much battery degradation. There is some fraying on the head portion due to aging, but it's not noticeable unless you look closely.
