Blackshark v2 bass sound way louder on right side

I have the Blackshark v2 with the USB sound card and have been using it for a while, but I've noticed that the bass is way louder on the right than on the left. I've also tried without the USB sound card, but the problem persists. (I have confirmed that it's the headphones and not my hearing.) The other sounds are completely fine and balanced, just the bass not for some reason. I don’t know if there’s a way I can balance it out or not. So if anyone could help me out, I would be very grateful!
