This is my 4rd Jabra bluetooth headset in 3 years. I choose this to replace my broken BT250v because it is lighter and slimmer. The first one that i received did not charge, so I requested a replacement. the 2nd seemed fine but it disconnects frequently. the operating range is said to be 33 feet but based on my experience it's no more than 4-5 feet especially during a call. the second that I change my position or the phone's I lose the audio, I can't hear anything but the caller can hear me.
