I've had 5 bluetooth headsets so far. Jabra was the first one I got, and now I'm back for Jabra. I had problem with it for a while; it kept dropping signals. I tried to update the firmware and now it's all good. I like the fact that customers can do their own maintenance.I'm very comfortable with the wearing, and I have no idea why some people complained--they might have special ear shape or size...I'm using it mostly as a stereo headset and the sound quality is quite acceptable. The only concern is its battery is not long as my other sets, it lasts about 5 hours when listen to music.
