Summary: I've go through 1 to 2 headset in a year. I've gone through many of them ranging from the earlier Motorola version, to the latest Plantronics, and the Jawbone Icon and Icon HD. However, all of them would either be uncomfortable to wear for long period of time, or don't feel secure if it is loosely fitted for comfort. In addition, all of them would either have drop connection due to some interference or unable to connect in time for the call. Very frustrating! However, Bose Bluetooth headset seems to address all of these issues and provide a good call quality and descent batter life. Although, Bose doesn't have neat features like caller ID announcement or batter meter/announcement like Jawbone. But if you are a serious bluetooth user on the road then Bose is the answer as it provides a good call quality with reliable connection each time. It is also comfortable to wear all day.
