My last blue-tooth was a motorolla 851. It was great. It turned on right when I flipped the earpiece and it automatically synced up with my phone and was good to go. The buttons were easy to work with.In comparing that with the Jawbone I just bought, the motorolla totally beats it out in all spades.Here are some good specs for the Jawbone before I give my neg specs: The jawbone does have that noise cancelling which does help a little bit with reducing the sound of outside distractions. I like the connection for recharge which has a usb outlet allowing for recharging directly from a cpu if I need it to. I like the way it looks; interesting.Here are the negs:1st: the fit isn't the best despite the 5 different pieces to accommodate for different types of ears. Perhaps it's just my ears; never thought that my ears were anything "out of the ordinary."2nd: It's hell hard to turn the thing on and off with me needing to press into the jawbone pretty good to turn it on and off. There were a couple times when I couldn't turn the jawbone off after multiple tries of pressing the off button.3rd: the connection is hit and miss... I had to reset the whole connection between the jawbone and phone at one point because the phone didn't recognize the jawbone. the buttons are hard to push whether it be for the volume or to turn the noise cancelling on and off... I think one has to be connnected with another person on the line to turn on that feature and 1/2 the time I can't tell whether the feature is on or not.4th: The quality of the sound from the jawbone is pretty muffled and the volume really isn't that loud even when turned to the maximum setting.Overall, I am pretty disappointed by this piece of technology that has been so hyped up by that video they played as well as a "raving" review from a friend who has it. I could've spent $26 on a great piece of bluetooth (motorolla) compared to the $80 I spent on this jawbone. Alas, I am too lazy to return the thing via amazon.I guess I will have to wear this piece of technology out before I get another one; unless I am annoyed enough to break it or give it away and get an older more tried and true blue-tooth.
