| The Bottom Line | The Plantronics Discovery 665 is a great little Bluetooth headset with amazing sound quality. But due to its lack of charging options, you shouldn't feel pressured to upgrade from the 655. | The Plantronics Discovery 655 has a great functional design that offers excellent performance. | The BlueAnt Q2 is yet another BlueAnt winner, with new Bing-411 features and fantastic call quality even in windy situations. | The Aliph Jawbone Era knocks it out of the park with high-end features, amazing audio quality, and innovative design. | If you want a quality Bluetooth headset that can be either mono or stereo, then the Plantronics Voyager 855 is an excellent choice. |
