clarity aloft...
I've tried a few.
Currently using the clarity aloft, TSO'd, with a QC15 as a spare back home.
I find the pro-Bose's a little to much (my head is big enough from before!) GA/piston-like and will continue to use my QA even tough my company introduces the Bose as we speak.
The Clarities are very light and simple, but still provide excellent passive noise reduction.
As for noise on the flight deck, the most annoying thing is when my colleague doesn't use a mic foam and I have to hear all the ambient noise through his/hers mic. I really was surprised when I learned that the Boeing didn't have speech-activated intercom!
