I own 3 Lightspeed zulu headsets (2 plane, 1 heli) and love them. Comfortable for long flights, amazing noise reduction, and the bluetooth is good for pre/post landing phone calls (or in flight hotel reservations as I did on the ferry flight across the US w/ a CFI). They are very durable, I've owned 1 for 7 years with no issues other than replacing ear seals. The other two I purchased used and they are still great. But carry an extra set of batteries, they're worse than non-ANR when the batteries die!
