BOSE QC-35 with U-FlyMike setup has my vote.

Great ANR, and excellent when you use the intercom switch in 75/76, maybe I would suspect same for other fleets? Then take the mic off for deadheads when listening to music, watching Netflix, etc...

I've happened to find rubber bands on the comm panel holding the intercom switch on, creating a true intercom. I didn't look closely, but maybe they were BOEING rubber bands?
