haedsets
Don't know about ANRs but I'm a David Clark fan. One thing I learned the hard way...get the best hearing protection you can buy. It's tempting to think that there's no appreciable difference between a bunch of headsets all rated at 22, 23, or 24 decibels, but that one extra db protection makes a difference after a long day, or after a few hundred hours.
Also, I find David Clarks compatible with every aircraft type I've flown, and every other colleague pilot's (other type) headset.
However, like I said, never tried ANRs.
