I have the Headphones DT990 premium, i want the best experience for bf3.

So i am using the Dolby Theater only for headphones surround on minimum, all other are off.

In game i heard to use Home Cinema and there was another option Enhance Surround or Enhance Stereo for surround Headphones and Surround speakers, should i use it or not ? is this the right settings for pinpoint gun fire location and footsteps ?
