Motorola SLVR L7c

I am a longtime Sony Ericsson user but am considering switching over to the SLVR. The biggest gripe I've had about Ericsson phones is that the microphone is so sensitive. It picks up every little noise and it drives people nuts when I call them from my car. Apparently it sounds like I'm in a wind tunnel. Has anyone noticed similar problems with the SLVR? I'd hate to switch phones and such just to get the same problem. Thanks in advance.
