Mobile Tech Review has a review of the Plantronics Discovery 655 and writes - “Comfortable to wear, good audio quality on most phones, easy to operate. The AAA battery charging option is good for business and road trips. Plantronics also did a good job with the audio technology in the Discovery series and the Discovery 655 has a good implementation of that technology including an effective DSP system. While it doesn’t come with the “space-age” 640 silver box, it does come with a nice selection of accessories. If you are looking for a small and lightweight headset with good audio, the Discovery 655 should be on your short list.”
