Thank you for viewing. This is a USB-connected in-ear headset. It's perfect for telework and online learning. I opened it but never actually used it, and it's been stored away. When I put it back in the box, it was difficult to repackage it as neatly as new, so the packaging has some scratches and scuffs, but the earphones themselves are clean as they haven't been used. - Brand: ELECOM - Model Number: HS-EP15UBK - Connection Type: USB - Usage: Online learning/voice chat - Design: In-ear - Accessories: Earpieces (multiple sizes) Please understand that this is a used item stored at home before purchasing.
