When I tried out stealth I thought it was really cool that I couldn't hear my footsteps, but then I realized there are more useful alternatives. In this game it just seems like a novelty perk to me.
I think it's a nice benefit on top of not being seen on Promethean Vision and that sort of thing. I definitely find myself using my ears a lot more with a headset than I do with my speakers, though. Last night I made a pretty solid heads-up play, when I heard a guy charging a boltshot around the corner, so I walked up and had my hardlight shield up, and when he shot at me, the shot rebounded and he killed himself.
Probably my most satisfying moment in any Halo game, ever.
