I have an Airman 850 and a Bose QCII w/U Fly Mike. In the CRJ-200, I don't use the 850. At the high gain setting, the chimes make my ears bleed and on low, I have to have the intercom all the way up to hear the other pilot. It's a shame because I love the light weight and comfort.

In the CRJ-200, I just use the U Fly Mike. Way mo better, IMO.
