Headset settings help

So ive been using regular headphones for bought a year (i got from my Mobile’s box)

But recently I bought a headset and am wondering what settings i should have.
Hyper X cloud 2 is its name.

Ive read its best to have Dolby Atmos instead of true 7.1 surround sound for locating footsteps and such (important for competitive mode). Something about it using the games engine instead of blah blah.

I’m not sure on how to use Dolby Atmos ONLY without the true surround sound. (do i enable Dolby Atmos and leave 7.1 button on sound card off?).

also id like your guys thoughts about which is better to locate footsteps best.

Another thing is i’m not sure if i should turn Loudness equalisation on?

Try it out yourself.
