Well you say that but looking at the Freq response there's +5 in the bass then it rolls dwn into mids then back into highs, so it appears to be bass emphasised, not like the Dt 990 or the Xb 700
and for "bass heavy" songs I can link you a few, the main issue with dub step and mid bass, is Wobbles r mid bass...
Very Sub Bass heavy, like a lot of ole school Dub Step
