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)?
