Bluetooth headsets differ from Bluetooth headphones due to the addition of a microphone - all the better to pick up your frenzied shouting over one kind of computer, and your tired muttering over another.
Whether you’re using it for work or gaming (and be warned, there are plenty of Bluetooth headsets marketed toward gamers), a Bluetooth headset’s value comes from cutting the cord between you and your computer. Whether you want to stride around, gesticulating wildly, during a video presentation, or take a break from your machine but stay connected while you go into another room (Bluetooth’s range is around 30 metres, so you can get quite far), there’s a headset available to suit you.
