In a previous article, "KevinBlack" said:
Personally (note and emphasise personal opinion) ANR leaves passive for
dead. I really liked my DCH20-10, but they do not come close to the
LS25XL/LS 30-3G as far as audio and comfort. I wouldn't go back to passive
unless there were no ANR sets available. Money well spent (and cheap
really) IMHO.

Man, that's true. I got the Headsets Inc conversion for my DC10-13.4s,
and I'm pretty happy with them. I was on an instrument training flight
soon after I got them, and my instructor noticed I was having problems
hearing the radio and him - then I noticed I'd forgotten to turn on the
ANR. Once it was on, problem solved.

That's when I was flying a four cylinder Archer. Now that I'm flying a
six cylinder Lance, I never forget to turn on the ANR because it's just
not fun flying behind that much noise.

I once saw an article from Flying Magazine in the 70s when people were
debating whether headsets were a good thing or not. Many of the same
arguments being made against ANR now were being made against headsets back
then. Especially the one about "not being able to hear the engine and
wind noise as well".
