Review on Poly Voyager 5200 UC Bluetooth Headset Bundle - Wall Charger by GTW, USB Dongle, Charging Case 206110-01-B, for Avaya J179, Smartphones, PC, MAC, Tablet, Softphones, Zoom, Webex by Roberta Carlin

Great headset but wish there were instructions included. I've connected another phone, headset, etc., but this device is so small and compact that the mute/unmute button is on the top of the mic, just above the mic, and you don't even realize it's a button . . I had to call Plantronics and have a technician walk me through the pairing process. Again, if instructions were included I wouldn't need to make a phone call. As for the USB feature that you can use on your PC, it works great. It's amazing how all these advertised features are implemented in this small, compact headset. It's quite expensive, but I'm very satisfied.
