This is a junk item. When connected to my own earphones, I observed symptoms of disconnection near the base of the 2-pin connectors on both the left and right sides. Both sides sometimes work and sometimes don't when the 2-pin area is moved. The above symptoms are just speculation, and I cannot guarantee whether repair is possible. Please consider this item for parts or with the assumption that it needs repair. Please consider this item with the understanding that it is a junk item. This is an auction for the cable only. The items I am selling include used items, so please understand that I cannot answer inquiries about usage period or frequency. Shipping is included, and this is a bargain item, so please refrain from price negotiations. Immediate purchase is welcome!
