I've been looking for a good bluetooth headset for a while. I researched and researched, and the PLantronics Voyager 510 got fantastic reviews. After using it for a few days, I have no idea what it is these folks liked about it. Every single call was filled with static, and every person I talked to stated I sounded terrible and asked me to turn the thing off and speak directly into the phone. This is a shame, I really wanted this to work and I've used Plantronics stuff before. Very disappointing.
