A headset won't help in Destiny much. You'll be able to hear gun fire and revives but you won't hear footsteps unless the buddy breaks his legs from falling. You can probably hear footsteps but your headset would have to be really loud and going deaf isn't worth it. I'm not saying don't get a headset. I'm just warning you it won't be to beneficial in Destiny but it does make any game feel more immersive and making you really appreciate the game more. It goes from being just some game to art in a sense, the music and everything gets a lot better. You feel more in the game but don't forget to go outside.
