EPOS SC 230 USB MS II noise-canceling USB headset (single-ear type), domestic genuine product. Purchased and used only once. At that time, it was used for about an hour with a cover attached, and then stored in a dark place, so it is in very good condition. The drawstring bag and the main unit in the images are for sale. Will be shipped via Mercari delivery. No smokers, no pets. Feel free to comment.
