As you discovered, ANR headphones actually allow you to hear MORE
detailed sounds, from the engine and other sources. All they do is get
rid of the loud, monotonous racket, and I won't fly without 'em
anymore.

Actually that "loud, monotonous racket" the ANR is designed to eliminate
comes mostly from the engine, so I usually don't turn on my ANR until after the
runup.

It would be nice if a stall alarm were routinely routed through the intercom.
25-35 years ago, when most of the planes we fly were made, it was common to fly
with no headset as if you were driving a car. Back then, one could actually
hear the stall horn, but now it is attenuated at least 12 db or so by the
pilot's headset. Why have it if you can't hear it?
