With regard to ANC, don't even think about not getting it. I

There is some question of the value of ENR (Electronic Noise Reduction)
in avoiding future hearing loss. Our company investigated supplying ENR
headsets in a high noise area, but decided not to, since there was no
demonstrated value. In short, ENR only works on lower frequencies, and
those frequencies typically don't affect hearing as much as higher
frequencies.

There were a couple of areas where there might have been some benefit,
but they were unquantifyable, so the company couldn't put a dollar value
on the systems. The use of the systems might have led in a possible
reduction in fatigue, resulting in improved alertness, and there might
have been improved clarity in conversations, reducing communication
error.
