Some competitive multiplayer games use sound cues that can be muffled by cheap IEMs or which don’t give you as good a directional cue as you need. Along with gyro aim and flick stick (or so I’ve heard) it’s one of the secret weapons of high-level play.

You could always crank up the treble even further, I suppose
