Bottom line the Jawbone works. It may not be as small as some of the other headsets but it does what it advertises it can do. The noise canceling feature works great the battery lasts twice as long as my cell phone. I have had multiple motorola headsets and a Jabra headset. The Jawbone is hands down the best headset. My only complaint is the ear loop, I have broken a couple of these but you are given 4 loops at purchase so it has not been a big issue. Again the Bottom line is if you want to hear and be heard, JAWBONE. P.S. My headset is still going strong after 18 months.
