for me its rather ear plugs _without_ nc. the nc cancels out the droning of the engine and aerodynamics but it leaves conversations, music and crying babies. with simple earplugs the droning (which i don't mind) helps covering up voices. of course anc + random noise is the silver bullet.

I can't even do this at home, let alone in a semi-public place around strangers. Being blind and deaf makes me feel uneasy.

Being 6'8" makes it very challenging due to no head support. I would love to come up with some kind of elastic harness rig that would also not be rejected by security protocols.
