About Gaming Part: I tried myself many expensive Headsets like Arctis Pro, Astro A40, A50, Sennheiser Game Zero for Valorant, CSGO, PUBG and Music/Movies and if you need an EQ, DAC, External/Internal Sound Card for an expensive Headset, dodge here, if you play only Valorant.
For Valorant all you need is HyperX Cloud 2/Alpha!! These don't want you to do something. You plug it in and you have awesome Sound for anything you do i meantioned.
Expensive Headsets are only good for Music and Games where you wanna hear Birds sing, the wind, every single Raindrop and 1.000 other Sounds. Expensive Headsets only pay out when you really wanna experience an Eargasm somehow. You won't benefit from these small details anyway.
The HyperX ones give you all the details that matter as strong as needed. No playing around with EQ or DACs or whatever.
I would recommend you buying HyperX Cloud 2 or Alpha for Gaming and any Studio Headset with a good rating for anything else, if you really want something for your Ears. You won't get both in one. Not even with the best EQ settings, because you also need the right Earcups for the experience you are looking for. And it's not worth transforming your Headset whenever you wanna do something else. I switched back to my Cloud Alpha and everything is perfect, again.
