The Blackwire 3215 is a wired headset from Poly (a brand of the HP Group).
It features a single earpiece, making it more suitable for call center use and for anyone who prefers to keep one ear free.
Thanks to its multi-connectivity, you can connect it to a computer using either USB-A or USB-C, and even to a 3.5mm jack on a phone or tablet, for example.
For comfort, the ear cushions are covered in simulated leather.
The microphone is equipped with a system that eliminates "background" conversations happening in your environment.
For convenience, you can access essential functions from the in-line remote control on the cable, such as volume adjustment and mute button.
