I have been through 4 different bluetooth headsets so far, and this one is far and away the best. The first was too bulky. The second (Jawbone) couldn't be carried easily when not in use, and got repeatedly crunched in my pocket until it wasn't functional. The third was a motorola flip version, and didn't stay on my ear well. This one fixes all those problems. The carrying case is truly inspired. It works great, and protects the earpiece when not in use. Best of all, you can charge it while it is secure in the carrying case. It fits well, even if you can't easily see the physics of how it will work from the images. Sound quality is great, but wind noise is still a problem. Always has been with headsets, so maybe next model. Overall, a great headset.
