Bose 700 "crackle" during plane takeoff (or in other loud environments?)
I used my new Bose 700s this past week on vacation, and experienced something odd during the takeoff of each of 3 flights. I'd be listening to music, and during takeoff as the engines revved up, the headphones would emit a crackling sound, kind of akin to the sound of a coffee machine percolating. I paused the music I was listening to, and tried toggling between the 3 NC levels (10, 5 and 0), but the crackling persisted. After about 30 seconds or so, once we were up in the air and the engine noise subsided, the crackling stopped, and it was fine for the rest of the flight.
My guess is this was a result of the noise-cancelling trying and failing to account for the loud, irregular sound of the plane engines during takeoff. Since the Bose Music app didn't work, I wasn't able to disable NC entirely to test this theory, but at some point I might try to see if this same thing happens when running like a vaccum cleaner or something.
Have others experienced this? Is this normal for noise-cancellation in this kind of environment?
