After several tries purchasing different BT Headsets its obvious it is a hit or miss deal.The JawBone is the best of the units I have tried to date, as this is hit or miss deal the best one can hope for is to come close to your expectations or spend a lot of money buying and trying. The Sound Processing used by the JawBone is very effective as it muffles the horrible road noise from my Jeep Rubicon, that is pretty effective. It is also effective at keeping back ground noise to a minimum, like running saws, compressors, and other construction tools. I want to say it lets me be heard, but cannot suppress that noise so I can hear, oh well I really didn't expect miracles.If one can get past the units size, which is more a visual statement than the actual heft to the unit. It is actually fairly light or light enough not to be a irritant, once you figure out the best adjustments to fit your ear the biggest PIA is putting in if its not worn all the time. I carry mine on my shirt using the robust sized ear retainer as a shirt hook and put it on when my phone rings.All in all this is a decent unit and if purchased online is a decent price, forget Best Buy etc. My wife does not like the size, but may also purchase one as the Platronics 665 IS NOT very effective at muffling back ground noise.
