This is a reliable, single-ear wired headset from Jabra. I used it because of its good sound quality, but I've switched to a wireless type recently, so I'm selling this one. The UC VOICE 250 MS is a wired headset that provides high-quality voice calls. The earbud attachment method is unique. - Brand: Jabra - Product Name: Jabra UC VOICE 250 MS - Included items: Original soft case Operation has been confirmed on my PC.
