There are some seriously large markets for headphone tech and they have nothing to do with being able to drown out the noise of a 747 engine or the background noise at a starbucks.
Take a look at the C4OPS headset system by Silynx[1]. The C4OPS and others like it are headset systems for combat communications. There are a lot of sounds in combat; some of the loud ones (gunshots/explosions) you would like to hear at a lower volume / with less fidelity and some quiet noises (teammate whisper/footsteps behind you) you would like to be more aware of.
