These are Sennheiser headphones. I bought them new from Soundhouse two years ago and used them at home for DTM, but I stopped using them because I felt they weren't suitable for mixing. I'm selling them to someone who's looking for them. The ear pads haven't deteriorated, and they're still in good condition. Operation has been confirmed. I no longer have the box, so I will pack them carefully with packing materials before shipping. #sennheiser
