| The Bottom Line | Plantronics' latest Bluetooth headset is an improvement over its first-generation product, but it doesn't provide the snuggest fit. | 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 Plantronics Voyager 520 Bluetooth headset has a comfortable fit, easy-to-use controls, and solid performance, all at a good price. | 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 Discovery 640 is a well-performing Bluetooth headset that offers first-class usability. |
