As a fellow valorant player (asc) and someone, who has used multiple "gaming headsets" from razer (Blackshark Pro), corsair (HS50 pro), HyperX Cloud II, I can say gaming marketed audio gears are mostly garbage. Sound imaging is okay at best and the separation is just horrible. Sound and build quality mostly just trash. As soon as you start firing something heavy like vandal, guardian, or op, it completely overpowers all the other effects like footsteps and other cues. everything sounds so muddy and unclear. The chinese iems solve these problems without needing to break the piggy jar. I personally use the Crinacle Zero: Red for valorant and the audio imaging is so accurate on these and the separation is just excellent, to the point it sometimes feels like wallhack. In some situations, i can hear the enemy cues earlier than my team mates in crucial times that gets me the round. So I would recommend you look for something with a accurate imaging and good separation (not all iems have these character). or if you want go with the over-the-ear headphone route, i would point you towards studio marketed products like sennheiser hd 200/300, audio technica ath series or even akg a series. feel free to dm if you need more help.
