| The Bottom Line | The Plantronics Voyager 520 Bluetooth headset has a comfortable fit, easy-to-use controls, and solid performance, all at a good price. | The Plantronics Discovery 655 has a great functional design that offers excellent performance. | 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. | ||
