Does it matter which side of the plane you are on or how close to the wing (engines) you are? I could imagine an audio difference between left and right if you were sitting at a window near an engine.
Just got back from another flight, where my seat was in the middle of airplane (3 set of rows). No issues whatsoever. One thing I’ve noticed, if I press AirPods harder, I do start hearing hissing in my ears.
