This is a wired headset made by audio-technica. One ear sometimes doesn't work, and normal operation is not guaranteed, so it is being sold as junk. I hope that those who can repair it, or who need it for parts or practice, will find it useful. Please check the images for the appearance. Due to the malfunction, no claims or returns are accepted.
