Get a better headset. The noise reduction in the mic of one (or more) of the
headsets plugged in is inadequate. I've used the gamut of different flavors, and many
of the well-respected brands have rather crappy noise reduction on the mics. My
cheesy $100 FlightLine 60HS-B passive headset had *great* mic noise reduction (albeit
at a lower sensitivity) than the Lightspeed 15K, 15XL, 25XL's I've used. Now I've
been using a Lightspeed QFR XC2, which seems to have noise attentuation somewhere in
the middle.

If you were to filter the noise out of the mic, you'll probably filter out the
voice signal you want too. Unless of course you do some very fancy filtering (read:
DSP)
