Purchased domestically from Amazon three years ago. I opened it to check, but I'm selling it due to the following condition: Only the left cable's audio output has been confirmed. The right cable (remote side) only has the remote functionality, and audio output could not be confirmed. Only one side produces sound, and it has been stored in a dark place for a while, so it is considered junk. Due to the nature of the item being junk, returns and claims are not accepted. The box and instruction manual have been discarded, so they are missing. Only the cables are included.
