Plantronics Bluetooth headset with HD voice clarity and multi-language voice alert functions. Single-ear headphone microphone. I used this about 3 years ago, but I'm selling it because I bought a different one and it's been sitting unused. *Power-on check completed on 2025/09/06* Everything in the pictures is included.
