Being a fan of industrial eletro and ebm i agree to an extent (especially what nuckin says about performance with vocals), the gr06 sound good regardless. if i want a higher ooomph level i take out the jvc xx (they are like $15 for f***s sake, sound great for electronic, so why not get both). I cant stress enough having a good al rounder gr06, pfe, hje and then some dedicated buds for your specific eclectic tastes. For me this is the jvc for ebm and when i listen to detailed stuff it is usually through the earsonic sm3's.
No one headphone is a do all tool just as no one screwdriver fits all screws.
That said the gr06 does sound great with the digizoid zo which puts makes it excellent for edm/ebm etc.
