I tried several headsets recently in a search to replace a really simple Jabra headset I had (the ear-hook finally broke). I wanted small and efficient design. I wanted something light that stayed on my head if I am working on my computer or working on my car. The Motorola H680 has done all of this. I like that it has a real on/off switch and not the typical mash the button into your ear for several seconds until it beeps method. The ear-hook is tiny on this headset and you can remove it or reverse it for either side of your head. i took mine off and the thing stays in just fine no matter what day to day stuff I am doing. It produces clear sound in my ear and others have no trouble hearing me. It synced to my iPhone easily. I would recommend this to anyone not wanting to spend an arm and a leg for a good simple bluetooth headset. I have a friend with a new Jawbone headset and the noise suppression system makes her sound muffled every-time she calls, for much less I have a good, solid bluetooth headset that I can hear and be heard on.
