I guess the above question would apply to speakers and open-type headphones specifically, but what are your theories?

I felt that my question was different enough, in that the thread you mentioned deals with temperature alone, but not specifically the temperature of the air, or headphone driver, or amp.. Just listening in general.
I'm asking specifically whether the characteristics of the air (such as pressure, temperature) can affect a driver's ability to put sound out (for example, an elevated location could have air that is less dense, and hence allows the driver to move air with greater ease). This could be especially significant with larger drivers that need to move more air, such as subs and large woofers.. I haven't tested this theory but I imagine it could make a much greater difference than, say, cables.
Sorry if that was not clear in the original question..
Have you ever taken your dynamic headphones on the airplane?
They sound thin at that pressure and it is the reason why I only use IEM's up there. I put them in near the beginning of the flight and keep them in the whole way through. Maintains the same air pressure and the sound doesn't thin out as much. Plus, you forgo the whole popping of the ears problem. Popping ears for some of us is extremely painful.
You will also fine that you need much more volume, even when you have some attenuation from closed headphones. It is just harder for the diaphragm to move with more pressure.
For me - it is not just the sound, but the fact that my ears do not pop.
