Razer blackshark v2 x

Hello guys i just bought the blackshark v2 x and i did some digging but seems like the issue im having is not common . I contacted my headphones and the sound is low , i expect them to have more power but i have everything at max but still sounds a bit low to me im thinking of returning them . Anything i can do to make it maybe better ? I have windows max volume, game max volume plus the knob from the headphones. Need help
