Poor audio in multiplayer

I know Halo has never been know as a FPS where you can really “sound -Yoink!-” but the audio in game is pretty bad. I don’t expect Valorant/counter-strike level foot step audio but I would like to be able to at least hear when I am getting shot at from behind. I know I am the only one who can’t even hear shots because I will shoot people in the back and they’ll have pretty delayed response as well. Especially in ranked where there is no motion tracker it would be nice to be able to consistently hear when I am getting shot at and somewhat be able to tell from what direction.
