Dave Clarkes are the ones to buy. Good attenuation, but with ANR, even better. Slightly bulky though but worth it to save your hearing.
Used a mate's BOSE-X headset the other week in a quiet aeroplane (turbine)and thought it was crap! Heaven knows what it would be like in your average flying club Cessna.
