High-quality headphone cable in collaboration with KIMBER KABLE. ★Please examine the photos carefully before purchasing; everything in the photos is what you will receive. Sound check performed on December 12th. Sounded great with no issues. - Model: MUC-B12SM1. Warranty card is included but expired. ★Regarding sound quality, this is my personal impression: I listened with Z7M2, and it was better than the original balanced cable. Unbalanced cables are more convenient as they can be connected to various amplifiers. - Length: 1.2m - Collaboration: KIMBER KABLE - Connector: 3.5mm stereo mini plug - Compatible models: MDR-Z7, MDR-Z7M2 ★Please refrain from price negotiations. Also, please refrain from purchasing if your identity cannot be verified. Thank you for viewing.
