Pros: Light weight. Good sound quality. Announcements are clear and audible... if they work at all.
Cons: Poor setup. No voice announcement of low battery status, you have to speak and ask for it. Three finger salute to reset. Dropped pairing repeatedly. Poor battery life. Poor support. Not a good experience.
Summary: I had a previous x3 micro which I loved and couldn't rate blue ant products high enough, just bought a T1, love having 2 phones connected at once, but the design is well short of expectations, (the x3 micro is much more ergonomic) and the first charge lasted only 3 days - less than 30 hours with less than 10 mins calling, so far the 2nd charge doesn't seem to be much better very disappointed so far
