I bought a Jawbone about two months ago after seeing the early reviews and commercials about the noise reduction technology and designer styling. After constantly struggling to have it stay in my ear far enough to hear on it, I'm giving up. I've tried all the ear loops and earpiece attachments, even tried attaching an additional Jabra eargel I read about to help keep it in place and none of them help achieve a snug fit that will stay in my ear. As far as the styling, it seems big and clunky to me, sort of a good looking design in the box, but a bit goofy looking on the ear. I've just ordered my third Plantronics 510, (I lost one and broke one)which is still the best fitting, best performing, and most comfortable for all day wear and heavy use.
