There is no question that Active Noise Reduction headsets offer
superior intelligibility and less stress than passive headsets.

Query: I haven't flown a light plane since 1981, so I've never had the
occasion to use ANR. When in use in a typical light single like a 172,
etc., can you hear the engine, or the airflow, or even your passenger
speaking (without benefit of an intercom)?

ANR mutes a lot of the low freq. noise. It's kind of like listening to the
world through speakers with the bass turned all the way down.

It doesn't suppress the sound of a human voice in the cabin much; it may
even make it more intelligible. You can still hear the engine, but if you
couldn't hear the airflow with a passive set, you won't hear it with an
active one either.
