I don't know much about these glasses, they were never used, they come boxed with a bunch of connection cables, manual , pouch. They're in nice and clean condition with minor wear and random scuffs. I will try to add a video showing that it works, if you don't see the video please send me a message so I can forward you the video showing that it powers on. it powers on fine and seems to work but I have no idea how they function, so please buy on the basis that they may not work as they should. NO returns.
