so i was always wondering why when i turn bass boost all the way up it barely changes anything and then i saw a video of someone doing a bass test with a piece of paper and the headset and there was a lot of bass. i have the razer kraken pro which connects via USB and most amps i see only have the audio jack thing and not a usb port. also i dont have a soundcard idk if i need one of those or not. is there a bass amp that has both a regular audio jack and a usb port in case in choose to upgrade my headset in the future to one that doesnt use usb. thanks for help
