Don't get me wrong the H3 looks good and sleek but it gives too much feed back. What I mean by that is that when your on the phone, the other party hears an echo.  This happend on all the calls. The only thing that kept me from returning it was that I lost the receipt and i threw away the box!  I don't recomend wasting your money on this. One you may try that has worked for me is the H500.  Cheap looks ok and best of all, it works!!!!  Oh yeah my Razor had a hard time linking to the H3.
