I bought theis headset because of other reviews and a recomendation from the salesman that sold me my phone. I have owned more than 6 Bluetooth headsets and this by far has the worst audio quality of any headset I have ever owned. The first call received was while I was at A restaurant in the waiting area with lots of chatter going on between patrons. he caller commented immediatly about the noise and I could barely hear him. I made another call from my vehicle after dining, and the audio quality at the receiver's end was so poor that the person I called asked me to get off  the headsset so he could understand me and even with the audio turned all the way up on my Blackberry Pearl, I could barely hear him.
