provides.

When you see the difference is over 10 to 15 db more reduction with
the ANR function turned on I'd think logic would dictate it'd be a no
brainer. OTOH I don't place much faith in advertising figures, but I
do place a lot of faith in what I hear (or rater don't) when I turn
that switch on.

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.

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