You might want to do a search on this one, because there are several threads about Chatterbox and autocomm, etc. Someone on the board recently posted that Chaterbox is supposed to be coming out with Blue tooth, where the unit isn't attached to your head anymore. Like I said, there are a lot of topics and opinions about this... I'll check back later, I used Chatterbox units for about 7 years before switching to autocomm.
