I think the plan is for everyone to try their headphones/headset they have and report with any tips or tricks, Mic compatibility and overall reviews
But you guys mean that on a more hardware on hardware compatibility basis, right? I mean, what
travisktl
is saying is that the 3D Audio aspect of the sound has nothing to do with the actual hardware you experience it on (headsets or headphones), it's something that happens on an internal level on PS5 and it's presented as a 2 channel stereo mix for any headphones. If there are any compatibility issues is going to be, quite simply, that whichever headset not working, just does not work on PS5, regardless of the sound mix it's supposed to receive.
Now, if some people have working headsets and their problem is that they don't experience the sound as anything more than a simple stereo signal, that's when things get complicated, 'cause then the issue is probably HRTF related, it being that that person is probably one of those outliers Cerny made reference to when speaking about the tech on the Road to PS5 talk.
HRTF (to be specific, HRIR) addresses the delays when perceiving sound from a point and that sound entering each ear canal at any given point in time taking into account each ear's positions regarding the source of the sound, replicating that delay so that you positively hear the sound presented to you on a spatially accurate form, same that you would in real life. The thing is, to replicate this accurately for each person, we would have to take into account everyone's ear canal shape, size, their head density...so, obviously, that's an impossible task. What they're doing is, having as much HRTF profiles measured as they can (remember on Road to PS5, the photos of Sid Shuman having his measured on an anechoic chamber), making some profiles that can be as "one-size-fits-all" as they can. But obviously that's not going to happen.
