| The Bottom Line | The Plantronics Discovery 640 is a well-performing Bluetooth headset that offers first-class usability. | The Aliph Jawbone Era knocks it out of the park with high-end features, amazing audio quality, and innovative design. | 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 BlueAnt Q2 is yet another BlueAnt winner, with new Bing-411 features and fantastic call quality even in windy situations. | The Samsung WEP870 is a great choice for those who want a convertible mono and stereo Bluetooth headset. |
