The Voyager 4310 Microsoft Teams headset has a one-ear design that helps you connect to your calls with noise cancelation technology, but does not completely disconnect you from your environment by allowing you to keep that one free of an ear cup. It features multi-device connectivity so that you can be paired to multiple devices at once whether at home or in the office. It also has acoustic fence technology and all-day comfort for long days of taking and making calls. The Voyager 4310 is portable and lightweight so you can carry it with you wherever work takes you.
