Truthear x Crinacle Zero

So I just am looking for new headphones to game with and saw a tiktok of a guy going on about the headphones listed above. I wanted to know if anyone uses them and/or if they're good with fps games. (I am currently playing a lot of Tarkov). I know that open back are better for fps just don't have the cash to drop on the set im looking at. Right now I currently have razer krakens but they are on their last leg. Thanks for any input!
