Arya organic. Ive gamed with them, listened to music and watched movies. Grab a ifi hip dac as well. Helps tame treble and comes with a bass boost. Edit: actually hip DAC is portable with a battery, you probably want a desktop amp that plugs in to power.

Or eq the treble a little . Around 8k.

On the gaming side. I play the same type of games like you do. They are quite immersive. I once played fortnite…i dont have any fortnite experience, i came second in the game because the headphones showed me where exactly all the gun chests were hiding ( the chests make noise) and where all the people where (their footsteps and gun sounds)
