Well, with all the hype, I had to go and take the 30 day challenge... I'm on day 2 and have already decided to keep it...
This headset has by far the best sound quality and design I have seen to date. Calls are crystal clear even in windy conditions... I was walking around outside on a call yesterday, it was a bit windy, and the caller on the other end never once asked me if I was outside or complained about wind noise...
I find Jawbone to be very innovative with their apps and am looking forward to see what else they come out with in the future. I installed the A2DP and music is playing perfectly... It was playing really low at first until I read their support forum to find you can use the call button (Press and hold) to increase it... Now it's near perfect!
I do wish the would come out with a stereo add-on that could possibly connect to the MicroUSB port... Similar to the Plantronics Voyager 855...
Otherwise, this is by far one of the best BT Headsets I have used...
