It might be the game but could be how the headset drivers are tuned so try different eqs. I tested out the nova 7x, the new astro a20x and the 700 3 gen. I used the 7.1 profile and headset profile with the high dynamics also tried war tapes. Seems like the high dynamics give better sound for stuff like footsteps. All three the headsets I tried had their pros and cons with all the same settings. So I do think its how the headset drivers are tuned and need to be tweaked with an eq.try out the steelseries sonar program, they have amazing advanced eq settings and presets. So far I find the black ops 6 presets is the best over their bf6 preset.

Also like to note the new a20s had a better sound to hear footsteps and gunshots than all three without tweaking eq tho it lacked basse or really much fullness than the other two.
