I purchased mine in 2006 and it would still be working now if my daughter didn't spill water on it for the umpteenth time. When I first got it I have to admit it made my ear hurt but I realized that I had it turned down too far and once I pointed it upwards a little the discomfort went away.I use it with a Palm Treo 700w and it has never given me a problem. It pairs everytime, volume is good indoors.The only con I can see with it is that it is a little too sensitive to surrounding sounds. When outside, people usually hear the wind or cars way louder than me talking. Also, I usually have to mute my radio in the car because it picks that up loudly too.
