I got aQFR XCc for my wife as a birthday present. As a result she
likes to ride with me on long trips a lot more. She really likes the
ANR.

I however found ANR annoying and I perfer passive only headsets. I
can't explain why I found ANR annoying. From a hearing protection's
perspective a good passive headset is more than enough to reduce the
noise to a level that's not harmful to hearing. The cabin noise level
in my Grumman Traveler is around 91 db at high power cruise. A 21db
reduction drops it down to 70db and it's a very safe noise level for
100hr a year. I use a Flightcom 4DX, a cheap utilitarian headset.
