Thank you for viewing. This is a bone conduction headset suitable for web conferences. *Box not included. - Brand: ELECOM - Model: HS-BC05BK - Connection type: Wired - Color: Black - Cable length: Standard [Usage period] Used for 3 months, then switched to Bluetooth, so I haven't used it since. The main unit and cable have no noticeable scratches or stains and are in clean condition. *Alcohol-sterilized. [Product appeal/recommendations] Just plug it into a USB-A port, but I used it with a MacBook Air, so I'll include a Type-C adapter. [Original box] No original box. I only used it for taking photos. Therefore, it will be shipped via anonymous delivery, Nekopos. I will pack it carefully and ship it.
