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 Gina Estevez

They work as advertised and cancel out most background wind noise. The audio quality for the person on the other end is a bit fuzzy but manageable. The handset also switches well between phone and laptop when I'm using Skype. The reason I didn't give five stars is that the headset sometimes randomly switches from Bluetooth to phone while I'm talking. That can be annoying. But overall I'm very happy with it. I probably spend about 5 hours a day on calls. The mute button on the mic is very important to me as I'm on conference calls most of the day.
