Should I choose a usb or 3.5 mm Mic, the headset i like is a corsair void pro RGB, it comes in usb, bluetooth, and 3.5mm. Should I buy the usb so I can plug it into my usb 3.0 port?
It depends where you want the sound to be converted from digital into analogue.
If you plan to use it on your PC/laptop only, USB will do. If you plan to use it with your phone as well, Bluetooth / 3.5mm will be better.
