No price reduction comments ❌ No individual sales ❌ No comments about operational checks ❌ 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 operational checks, the headphones were charged with a USB cable I had on hand, and only 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 operational status for both the main unit and the headphones, so please understand this. Other detailed checks have not been performed, and repair and maintenance are required, so please purchase if you understand and have the knowledge to do so yourself. (Please refrain from purchasing if you are nervous or ask detailed questions) * Accessories (adapters, chargers, etc.) are not included. * There is no guarantee of quality or operation after purchase.
