Thank you for viewing. This is the Sennheiser HD 598 Cs. I used it for a while after purchasing it, but then I bought another pair of headphones, so I'm selling these. It had been left unused for a long time, and the fluffy part of the soft pads had started to crumble. I removed all of it during cleaning with alcohol, so you can use it immediately without any problems after purchase! - Brand: Sennheiser - Model Name: HD 598 Cs - Cable Type: Wired - Ear Pad Material: Soft Pad
