The Bottom Line The Plantronics Discovery 640 is a well-performing Bluetooth headset that offers first-class usability. Despite its finicky controls, the Plantronics Discovery 975 is a stylish headset with a comfortable fit, a great feature set, and excellent call quality. The Plantronics Voyager Pro might not look like much, but it has the best sound quality of any Bluetooth headset we've ever tried. The Aliph Jawbone Prime is a great Bluetooth headset that combines high style with high performance. The Plantronics Discovery 655 has a great functional design that offers excellent performance.
