Hello to everyone

I bought Razer Kraken V3 headphones with USB. I'm trying to adjust the settings via Synapse, but nothing changes, even if I switch to THX.

I saw that THX appears in the Windows sound options in some places, but I don't have that either. Only Kraken V3 is coming out. And as I said, I can only adjust the volume and lights with Synapse.

What do you think could be the problem?
