Review on 🎧 Efficient Connectivity with the Plantronics Blackwire 5210 Wired Monaural Headset - Ideal for PC, Mac, Tablet and Cell Phone by Melissa Hart

I received a headset for work because it was one of two approved headsets. I used the headset for the second day and every time I pressed the mute button it just said to mute, although I pressed it multiple times and it never said to mute. On the first day I had no problems with the mute button or the volume button. The volume button occasionally got stuck and the displayed volume was maxed out, although I may have only pressed the volume button twice. Maybe I just caught a defective headset. The ear pads are very comfortable on the ears and the microphone is very clear.
