Sound quality is a 5, no question. The problem for me is that I wear an outer vest which I take off when I'm at the station, so my speaker/mic/wiring all goes under my work shirt. The connector is very bulky and pokes out of the back of my shirt. There's no way to clip it anywhere other than on the inside of my collar, which then makes the speaker wire WAY too long. I had to coil it up and tape the coil so there's some tension, otherwise the earpiece falls out of my ear. I wish there was a way to shorten it. If you wear an under vest and can clip the connector to the bottom of it you will be fine.
