Hey,

I don't know if this rings true for everybody, but I can vouch for the pressure effect.

When I came to India on an airplane, the airline (Continental Airlines) provided these horrible, horrible in-ear headphones to use with their entertainment centers (surprisingly, all the stuff was free {movies, games, and music}).

I watched Shawshank Redemption on the way over and just had no idea why the headphones sounded so low when I used them at full volume. I assumed it was the cheap build quality.

Little did I realize, when I got to the airport, I noticed that the volume level was much different off-board. It hit me then, that the great difference of inner ear pressure must have caused it.

I pondered this and speculated about how the same thing happens when on a bus ride and when driving down a highway in a car.

I know about noise-canceling headphones and have even seen them in Bose ads (yeah, I know Buy Other Sound Equipment) where a guy puts them on in an airplane.

I just don't know, is there something specifically suited to maintain an adequate level of volume, in spite of varying conditions?

I like IEM's for air travel. If you want to use with their "entertainment" get an adapter and stick with easy to drive IEM's. I hate edited movies and canned music so I roll my own. I am guessing something like ERS's would not be so good for use on airline systems, but these are my favs for noise isolation.
