I purchased the Jawbone to replace a couple of older Motorola headsets for a Moto phone. I thought the headset might perform better in a noisy environment like being in my moving convertible. It does a better job but only for noise that has a steady pattern, like the lawn mower in Aliph's videos. If you are listening to your radio and a loud song is playing, the Jawbone is only a little better than the others. Other reviewers complain about how it fits the ear and the "tinny" sound...all true. What I found is that my phone has a harder time understanding my voice commands with the Jawbone than with the Motorola headset or any other Bluetooth headset for that matter. I might be too fussy, but for 2 times the price of a comparable headset I'd at least like to to perform as well.
