... consider allowing the use of noise canceling headphones during takeoff/landing.
I like to put mine on immediately upon being seated so I can listen to the audio program as well as the announcements over children howling. But if the CC spots the little green LED, I get told to shut the off. Not take them off, just switch them off. So now I can't hear the PA system announcements.
I suppose a small piece of black electrical tape could solve the problem. But I'd like to comply with the rules.
