I have tried serveral headsets. I was very immpressed w/ the video on jawbones website....I decided to give it a try, and sure enough it blocks out all background noise. I did a test w/ a co-worker, driving into work....w/o the noise shield turned on, he could hear the radio in the background, but when I turned on the noise shield, he only heard my voice...I even cranked up the radio & he could not hear....the problem I had was it didn't fit my ear well & I had a hard time hearing.....I sold it to my co-worker. Then I bought BlueAnt Z9, I liked the features & capability of firmware upgrading. It fit so much better, and I can hear alot better too. When I repeated the test w/ my co-worker, he said it did not block the background noise as well. Also, I have had specific complaints while driving w/ the window down about the wind noise.

Both are really good headsets, but I'd say Jawbone has better noise reduction technology......and this was using their v1, I think they have a newer version. Still have my Z9 & use it everyday.
