For every usage situation, there's a Poly office headset to suit your needs. For example, choose a wired stereo or mono headset if you have lots of meetings and calls in one place, or choose a wireless headset if you want to walk around while calling. If you work in a busy work environment, there are also headsets with active noise canceling. Those filter background noises, so you can fully focus on your important calls. Want to make hands-free calls, but not be completely cut off from your surroundings? Choose a Bluetooth headset.
