The polyurethane parts of the head and ear sections are deteriorated. I haven't checked thoroughly, but the left side doesn't produce sound, so I'm selling it as junk. Please understand this. When using it for DJing, I mostly used one ear, so I didn't feel much inconvenience. Please purchase only if you understand that this is a junk item and a used item, and with no claims and no returns. 【High Sound Quality】 Technics headphones provide clear sound quality and are perfect for DJs and music production. 【Durability】 The sturdy design can withstand long hours of use. The gold-plated connectors minimize signal loss. 【Comfortable Fit】 Soft ear pads fit your ears and provide a comfortable listening experience. Technics I see many people still using them actively after restoration. Please consider it. Thank you for viewing.
