If you want soundstage so you can hear footsteps in CSGO, try Audio Technica AD700, it has very big soundstage so pinpointing enemies are easy. However the game is trying to eliminate any hardware disadvantages so it would be fair for everyone, so any headphones and headsets are fine really. Also the Razer Tiamat "Surround with multiple drivers" are a gimmick, it doesn't really work. If you really want soundstage, you can try using Razer Surround software.
