You are buying a lot of 2 OEM remotes model # A2128200097

And 2 Headphones. 1 Headphone is OEM and 1 is aftermarket.

This set came out of a 2013 GL Mercedes and works perfectly. One of the remotes has a broken battery cover but works fine. The aftermarket headphones worked fine in the vehicle but I'm not sure how to set them up initially.
