Thank you for viewing. This is a balanced cable for SONY headphones, designed for input with two mini-plugs, such as the SONY PHA-3. I used it with my MDR-1A. 【Compatible SONY Headphones】 MDR-1A/1AM2, MDR-1ABP, MDR-100A, MDR-H600A This product costs around 8,000 yen if purchased from the Sony Store. The outer box was once crushed and squashed, and the outer and inner boxes have considerable damage (creases), but the cable itself is in good condition. Immediate purchase is OK. I will ship it on the same day of purchase, or at the latest, the next day. Thank you.
