Mick Gordon’s soundtrack is legendary, and the Switch audio compression is... acceptable. Audiophiles will notice the compression artifacts in the heavy guitar riffs compared to the PC version, but through decent headphones, the soundscape is still immersive. The directional audio is excellent, allowing you to hear a Hell Knight teleporting behind you even with the screen looking blurry.
