I have seen the 850’s on the Airbus and 757 , not so much on the 737..

And I am seeing more and more guys in the bus in EWR with ANR headsets , keep in mind this is a junior base with newer upgrades. Meaning newer generation which I do believe seeks ANR headsets more often.

It’s most of the old school cats that seem to care less about hearing I guess.

What ever floats your boat.
