Great topic. The core issue most people underestimate is that HRTFs are intensely personal—generic profiles baked into Windows Sonic, Dolby Atmos for Headphones, or even most game engines use a “average” head model, which means your spectral notches from pinna diffraction won’t align with your actual ear geometry. That mismatch is exactly why some players perceive convincing elevation cues while others hear everything as “in the skull” or struggle with front/back confusion. The pinna’s ridges and concha create frequency-dependent reflections that produce those signature spectral peaks and dips—usually above 5 kHz—that your brain uses to resolve ambiguity along the cone of confusion. When the HRTF doesn’t match your ears, those cues flip, so a shot from behind can read as coming from in front. For competitive play specifically, this is a real, measurable disadvantage, which is why I’d
