Power up productivity for office workers with Voyager 4200 Office Bluetooth wireless headsets. Roaming range is generous, and vibrant sound is a given.

Your teams can count on superior Poly audio clarity—and comfort, thanks to soft ear cushions and an over-the-head headband. Plus, there’s outstanding noise canceling and dual microphones to help block out nearby talkers.
