Decided to listen to some songs (specifically, the OTGW soundtrack) relatively loudly, in a quiet room with headphones on. It was like a completely different experience. You can hear rustling clothes, people taking in breaths, general fleshy human body noises, the piano pedal squeaking, whole new instruments I didn't hear before.
Been messing around with programing macros for Warzone, nothing too fancy but having quick commands available helps. The movement keys AWSDC are so close together so it helps when mashing keys in ultra quick succession.
