I was using a refurbished item purchased second-hand. This is the normal version, not the stealth magnet version. This is an auction for the main unit, an unbalanced cable, and replacement ear pads. I purchased the right side with a repair history, and because the sound wasn't stable, I replaced two wires inside the housing. The sound quality sounds the same to my ears, but those with a good ear might notice a difference. The headband was falling apart, so I replaced it. During that process, there was a slight crack in the parts (see photos 10 and 11; I don't think it will break from here due to the structure). There are many other small scratches and signs of use. The cable has a slight bend. Operation has been confirmed. The sound is currently working without any problems, but it might be better for those who are able to repair it themselves. For those who need them, I'm including the same wires used for the repair and two 3.5mm sockets as a precaution, as the right-side 3.5mm socket is slightly damaged. These are compatible replacements.
