No price reduction comments ❌ No individual sales ❌ No operation check comments ❌ Thank you for viewing. Please read the description and condition. My brother owned this, a SONY Digital Surround Wireless Headphone System MDR-HW700 and DP-HW700, which is a junk item with unknown operation. Regarding the condition, the headphones have deteriorated head and ear pads, which are peeling off. The main unit also has scratches, scuffs, and dirt. Regarding the operation check, the headphones were charged with a USB cable I had, and only the power-on confirmation was done (photo 12). The main unit does not have an adapter, so I don't know if it works. This is a junk item with an unknown operating main unit and headphones, so please understand. Other detailed checks have not been performed, and repair and maintenance are required, so please understand and have the knowledge to do so yourself.
