Headsets-what's the best NR headset?

[Walrus]

I'm trying to decide what is the best noise reducing headset for two crew turboprop work. I'm considering the David Clark H10-13.4 because it feels pretty comfortable, but there's a lot of choice out there. Also - is ANR the way to go? Ta.

imho, Sennheiser HMEC 25 for noisy flight deck, HME 45 for jet flight deck. Supremely comfortable, the 25's noisegard sysyem works very well.
