I ordered this over the weekend and just got it today, very fast shipping. Installed it and started to use it, those that I have called cant tell any difference between talking on the phone and the hands free though I would suggest to make sure your talking at the mic and not away from it. I have a HTC EVO 4G thru Sprint and it had no issues syncing that I have seen so far. if I can I will update if I have any issues to talk about.
