Price negotiation OK! This is a Bowers & Wilkins Px8 wireless headphone in black. I've been using it for about six months. I don't think the sound or battery life has deteriorated much at all. There's a small scratch on the underside of the headphones, so please refrain from purchasing if you are concerned (see image 4). If you'd like, I'll also include the headphone stand in image 5. I've disposed of the original box, so I will pack and ship the headphones in their case.
