I know a lot of people don't find the 650s to be bass heavy headphones, and I agree! However, you can get the bass to go pretty hard on them. I downloaded sonarworks demo, and copied the "average" eq curve for the 650s (flat) into the graphic equalizer pluggin in foobar, also using the real bass exciter pluggin, and yeah...earthquake bass!
