content: I have purchased several bluetooth headsets in my attempt to obtain a good quality sound. I purchased the Nextlink AX2 with the hopes of solving my search. I was not impressed. It was loud enough (as they stated), but with the volume turned up it created an echo for the recipient of the call. It is a ROYAL pain trying to get the thing in your ear while driving. Once in, it was fine. I hung up on several calls while attempting to secure it in my ear.I have put the whole thing back in the package and will try to return (though for the $30 less shipping both ways) it probably isn't worth my time.I have gone to the expensive H700 MotorolaAs they say -"you get what you pay for"
