Excellent Bluetooth headset. Works better than the Motorola H700 and H850 which I own. I was skeptical of Plantronics at first seeing that I owned two top Motorola Units. I found Plantranics to offer better sound quality (both send and receive) and was extremely pleased. Although sligthly heavy, the unit is very comfortable for long wear and it works great in the car with noise. I would buy again any day over Motorola
