THX headphone

I can't figure out THX sound, I have a Blackshark V2 Hyperspeed, they have THX sound support, I downloaded Synapse 3, as soon as I select THX Spatial Audio as the default device - Synapse immediately pops up a sign that requires me to disable THX sound, I tried ignoring the sign but the sound stopped working altogether, tried uninstalling Synapse, reinstalling drivers, changing headphones, nothing helps. From what I understand, I don't have a proper audio card in my motherboard. I would like to know if I can buy the necessary audio card separately and if there are headphones with built-in audio card? If there are such, please advise me, because on the Internet I did not find the necessary information. Thanks in advance.
