You guys must have gotten one of the first sets that Apple put out. I got my 1.25 MMD G4 in November of 2002 and while it isn't the quietest, it certainly doesn't do the windtunnel or blowdryer noise like the first ones did.

I haven't done any modding to it to make it quieter. It does make a noticeable noise, but it is fairly even and doesn't interfere with the phone, music, or other.
