I really love the way this works re. hands-free operation. There are a couple of things that the manuafturer might want to look at however. First, it falls apart easily. In order to keep it together, I put a black rubber band around it. this is the second one I have had and the first one did the same thing. The other thing is, it flashes a blue light intermittently and is a source of irritation, disrupting concentration when in conversation with someone while wearing it. Lastly, there is some distortion in hearing at higher volumes, but difficult to hear at all in lower volumes.
