This is a Sennheiser GSP 600. It's missing the box, and the headband is cracked. The ear pads are peeling, and the overall condition is poor, but the sound quality is fine and it works without issue. Operation has been confirmed. This is a used item. Everything in the photos is included. Since the original box is missing, it will be shipped in a different box. For the headphones, it's recommended to purchase and install replacement ear pads, as compatible ones are available cheaply. The cables are original, in good condition, and work perfectly.
