The Jawbone performs as advertised. Had trouble with the fit at first but, following the advice of previous reviews, I purchased the Jabra EarGels at Radioshack and was off and running. I don't even need the earloop!! It stays firmly locked into either ear. I use this headset not only when I'm driving but at work in a noisy enviroment.....heavy equipment in the background. Wind is still a problem but to my knowledge nothing out there filters the wind any better. The Jawbone does the job for me.....I'm very pleased with it.
