Xbox One X:
with Sony XM3 headphones, or 11.1 Atmos HT
Call of Duty: Black Ops 4
I had a lot of fun playing the battle royale mode (Blackout) for about a year. The sound however was disappointing: No Atmos; 7.1 surround was respectable; but the headphones experience was utterly non-directional whether I used Stereo, Windows Sonic, or Dolby Atmos for Headphones.
Call of Duty: Modern Warfare (2019): my first impression: stunning graphics and spectacular 3 dimensional sounding soundstage - including height - from headphones using Dolby Atmos for Headphones. wow!
