The 30mm drivers here are the same as Sony's WH-1000XM6 headphones, so you're getting rich audio as a baseline, with some EQ presets designed specifically for effects you'll encounter in FPSs, like footsteps, gunshots, and directional sound effects. Notably, however, they're smaller than the 40mm drivers in the H9, supporting Sony's goal here in allowing for clearer, more detailed sound.
