Sennheiser Model Name: MOMENTUM 4 Wireless I really don't want to sell these at this price, but I'm reluctantly offering them at this price to declutter. Sigh. I'll lower the price if they don't sell. I bought these new on Amazon and used them for about six months. I didn't use them very often, and I always "aged" my headphones for about 10 hours, so they're already broken in. All accessories are included. The top of the headband, etc., has no major scratches, and I think they're in beautiful condition, but they are used, so please refrain from purchasing if you are sensitive to such things.
