Since you mentioned that you are interested in the Sennheiser HD 598's i asked my sister if i could use hers (i use the 580's). The game that i tested them with was Rainbow Six Siege. When i put them on, i noticed that they have a very good seal around my ears even with glasses on. The 598's were good at distinguishing where sounds were coming from. Mainly from the sides, above, and below. I had difficulty telling if sounds where sounds were coming from if they were directly behind me or directly in front of me (not sure if all headphones are like that). The sound quality was good. I would definitely recommend the 598's for gaming and music.

For me, one of the What moments with gaming headphone was when i tried using Fostex TH900. Till now, i think it is the king of gaming headphone, besting HD800, HEK, Z1R, etc

1. It has amazing positional cues. To my ears, it is better than HD800.
2. Soundstage is smaller than HD800, but it is larger than most headphones.
3. That Bass!
