Personally, the left ear.

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.

I did sit on both sides (one flight was next to wing) - did had same issue both times.

One thing that was common- I was sitting in a window seat.

Seems pretty odd that all the reports are about the left ear.

with buds, whichever connects first (usually right) is the master, and the other bud connects to that one as the slave, instead of connecting directly to the source device. probably has something to do with that
