(Management number: mwt0561pj) This is a SONY 7.1ch surround sound wireless headphone. Includes the main unit, charging stand, optical cable, and AC adapter (compatible). I was able to confirm that audio comes out from the TV. *The headphone battery is a consumable item and is not covered by warranty. I haven't tested it until the battery runs out, but it's not in a situation where it dies immediately. The ear pads are in good condition with no tears, and I think it's a beautiful item. Thank you.
