Sorry for such a late reply. If you want headset then the best option in my opinion is to get Kingston HyperX Cloud Core from AliExpress for around $50.
If you want headphones then Superlux HD681 Evo is a good option for around $41. Superlux HD668b is also excellent for gaming and is even cheaper for around $30.
If you want to buy locally and new only then Edifier H850 is very good in my opinion and is available for around 4k. Although I haven't used it for gaming so can't comment on its gaming performance. And it requires a bit more power than other headphones I mentioned. I have to turn volume up a bit up when using H850 to get similar sound volume as other headphones.
About the Siberia v2 (used), don't buy it online and buy it in person only. Currently Hafeez center is full of Siberia headphones which have changed pads, wires and maybe drivers as well. Check the headphone in person to see if you can spot some repairs and play some music from your phone to see if you like quality and volume level of both sides is same. If you like the sound quality then why would it matter if it has changed drivers
