SONY MDR-CD900ST I purchased these for recording, but I haven't used them much, so they are relatively clean. I've only used them a few times. I opened the replacement ear pads to check their condition. I didn't see any deterioration in the pads. I will ship them in the original box they came in. There are almost no scratches. I have confirmed they are working. I used them a few times at home and have since stored them in a case with a desiccant. To prevent any issues, please refrain from purchasing if you are overly sensitive to used items. ★I will not accept price negotiations. Returns are not accepted.
