Disappointed with this headset, although I have tried just as bad or worse. Based on others' reviews for Treo 700, I tried it and do not like that there is almost constant static on the headset, and the bluetooth range is significantly less than 10 feet. People tell me it is like listening to me through a tunnel; sound quality is pretty bad most of the time. The great feature about it is the finding it feature, which worked for me immediately and quite well. All headsets should have this feature as a standard. This is not enough for me to keep it; I am returning it.
