That’s true on every platform but PlayStation. My take on VSS is that it works as intended but you gotta deal with the reverb that comes with it. And not all games have it’s own headphone mix or it’s mix has terrible positional audio, all Call of Duty’s before BO4 for example. So using software or an external device can help with that issue.
However, all of that stuff is gonna be irrelevant in a couple years since sony and Microsoft are now trying to push for better audio with their next gen consoles.
