After spending more than 50 hours researching 30 headsets and testing nine of them, we’ve found the wireless Plantronics Voyager Focus UC is the best headset for people who make frequent calls and listen to music at a desk. The wireless headset connects to your computer and mobile phone at the same time via Bluetooth, making it easy to switch between the two to handle calls or music. Its softly padded earcups and unique suspended-cushion headband made it the most comfortable for all-day wear among the models we tested, and its battery performance was among the best, as it lasted a full 8-hour work day with juice to spare in our tests. In our audio tests, its voice, music, and podcast audio quality were among the clearest, and its active noise cancelling successfully blocked out ambient sounds, which is especially useful in a cubicle or open-office floor plan.
