What type a/c are you going to be using the ANR in? I have a Bose X and am VERY happy with it. The ANR works great, but for me the light weight and comfort of the leather ear cups are as much a deciding factor as the ANR. I know DC and others make ANR, but they basically took one of their existing headsets and added ANR, so you still have the high weight and clamping force. Having said that, the Bose offers almost no passive noise reduction, so if the ANR is off, it will be noisy. Whereas the DC will still work as passive noise reduction if the batteries or headset fail.
