Stepping back from ANR

Your logic is flawed. Human hearing is most prone to noise-induced
damage at higher frequencies, where ANR has no effect. In fact, in this
regard many passive sets provide more protection.

You may want to read:

http://www.anrheadsets.com/tutorial101-2.asp

for a primer on the different issues related to frequencies and
damage. Granted, LS has a vested interest in selling ANR headsets,
but the whole ANR tutorial seems to be well balanced and factual.

There have been long-term studies done on hearing protection afforded by
passive devices, which have been proven to significantly reduce the risk
of hearing loss.

Absolutely correct. Almost any hearing protection is better than none.

.... While I'm not suggesting that ANR devices are worse,
there is no data to suggest that they're better.

Yes, there is - see the above reference.
