Why don't ears pop?

I've often wondered this. If somebody speaks into your ear, you do not hear
the pop you often get on a microphone in the same position do you. Likewise
when listening to music in a hall with your ears and then over headphones
from a set of mikes you notice the echo on the latter but not on your ears.
People say its the way the brain processes the sound, but if that is the
case maybe now we can actually emulate this in some way for recording?
No I don't mean going back to a close miked up every single instrument and
a mixer you need to be Twizzle to operate.
