Kraken USB sound problems

Hey there, I changed the bass in my Razer Kraken USB settings in Razer Synapse 2.0 to see how it sounds. I don't like th e sound and would like to get the old sound back, but if I turn the bass to 0 it has still too much bass. Does somebody have ideas to reset the settings or something else to get the old default sound back? Keep well, Florian
