I am a little surprised at the big difference between the various site reviews and the user reviews for the current models of Jawbone mono headsets. I am still using the original Jawbone that I purchased in 2007. I've never been unhappy with it up until the last 4-5 months when it began showing it's age. I recently began looking at the various models out there today with the thinking that I would defiantly go with one of the Jawbone models again but have been disappointed to find so many negative user reviews. Doesn't mean I won't go with one of them but I want to see what the rest of you like and don't like. I would especially like to hear from those of you who use the Jawbone Era & Icon models.
