Sennheiser HD650 headphones. I bought them several years ago. No smoking environment. Included items are the headphones themselves, 6.3mm cable, 3.5mm adapter, instruction manual, and storage case. I didn't use them very often, so I think the main unit is in good condition. Please judge from the photos. Regarding the cable, I tested it and it seems to work, but it might be better to replace it since it's been several years. The storage case has some stains. No claims and no returns, please.
