Not another "what headset should I buy" thread. Has anyone/does anyone use their ANR headsets while a passenger on commercial flights? I ask because I have to travel commercial for work. Instead of purchasing a dedicated set of ANR headphones, and a separate set for flying, if feasible, I would like purchase one pair and get use during both activities. Any feedback/thoughts/advice on whether or not this is worth pursuing would be greatly appreciated. Thanks in advance.
