I agree with you Sparkomatic. The delay in the 645 when you answer a call is really annoying and sometimes it is hard to tell when you have a connection with the caller.
Yesterday I was riding in a Lincoln Towncar @ 70 MPH and tested the 645 by calling my office voice mail. There was still a lot of road noise in the background. My voice was loud but the road noise is still in the background. Not nearly as bad as the 640 but it was still there. The radio noise was blocked out for the most part until I turned the volume up louder than what I normally listen too.
For fun I purchase a Cardo 500 for around $35 and I get the same results as the 645 as far as road noise in the background. Audio quality on the other end is about the same but not as good in my ear. But not a huge difference.
I am beginning to wonder if it is my 8700c. My old 640 worked great on my Razr and people did not know I was on headset.
I really do not want to carry around 2 phones!!

1. The volume was too low. My 640 has a higher volume.
2. When a call came in, there was a big delay from the time I pressed the answer button (on either the phone or the headset), until I could start talking. Again, my 640 didn't have that much of a delay.
Don't know if the 645 just doesn't like the 7130e or not but I'm back to my 640 until there's a better headset out. I even tried a Moto h605 and Plantronics 510 but they weren't as good as the 640 IMHO.
