Thank you for viewing. I purchased this on the release date and tried it on once to listen to music. There were no issues with the operation, but please refrain from purchasing if you are concerned as it has been handled by a person. As this item is currently sold out, I would be happy to pass it on to someone who is looking for it. The glasses themselves, a charging cable (USB), a glasses cloth, a case, and the instruction manual will be sent together. Thank you very much.
