I just received and installed the new "762" mic. All I did to test, was to make a call to my answering machine at home leaving a message with the old mic, and then the new one. I can say that the new mic is clearer and does a better job than my old mic part # 84318380338 at diminishing background noise. It's not light years ahead, but it is indeed clearer. Note to benathon, in neither test did I sound "far away".
