I have a very old Echelon ANR headset, that I actually still like. (I didn't buy it, I was given it by a friend who had given up flying.)
However, not long ago my wife bought me a trial lesson in a helicopter (loved it), and the instructor gave me an Bose A20 to wear.
Wow, what a difference. I instantly fell in love with it, if not the price. Since then I have been trying to justify the cost, but haven't managed that bit yet!
