Thank you for viewing. This is a listing for radius wireless earphones. I've used them for a long time. Suddenly, the sound stopped coming from the right earphone, so I'm listing it as junk. When I perform a reset operation, the lamp lights up and the power turns on, so I don't think the hardware is broken, but it won't turn on when I try to use it. The left earphone and the main unit work normally. Since I've used them for a long time, there's a general feeling of use. (Please check the photos for scratches, etc.) I would appreciate it if you could consider this as a used item. Other features... Junk, Noise Canceling
