Pros The headpiece is simple and pretty easy to use.
Cons The headset is very slow. when you go to hang up from a call or connect to a call you have to wait and unusually long time. The earpiece is not the most comfortable. The main button is hard to reach when in the ear.
Summary The earpiece is simple and doesnt have a ton of bells and whistles. The earpiece is the same size but the band to hold the earpiece in is the only thing that is different. Every time my wife and I used the headset to call we would get static which was really annoying. The environmental mode was cool but not always good enough to be completely useful. If the earpiece turns slightly then you wont be able to hear the environmental mode as well or at all, it is also very noisy and if you have a squely kid make sure you have it on low or you may no longer be albe to hear... The battery life is better than most but the environmental mode eats into that a little bit. The main button is very hard to reach when you have the earpiece in your year and you almost have to remove it to push the button. There is no voice command or even voice response, it is a very simple unit. The sound is not as clear as i expected it to be and really was not as clear as any of the competitors that we have tried. We also got an echo most of the time which was really annoying.
If you have a choice of the major ones i would suggest the Blueant Q1 which is what we ended up going back to.
