The only issue I have with mine is dropping calls on UMA when I switch to EDGE on my Jawbone 2, this is a known issue and I am sure it has something to do with the connection being dropped ever so often. I have this happen as well at home, have never had it happen in the car and this thing is in my ear probably 10 hours out of the day. Never tried the Jabra, had BlueAnt and the plantronics and neither could touch the Jawbone 2 in noise cancellation so I will take the minor issues for the convenience.
