The Plantronics Discovery 640 offers great audio quality, multiple charging options, a compact design and a secure fit. The ear hook, as shown is uncomfortable though, and its buttons are small and difficult to press. It is also not compatible with all mobile chargers, thus you’ll have to carry an additional charger with you.
