hmm damn alright. i'm actually not a huge fan of the xb500s either despite putting at least 2000 hours of solely music listening into them so far because the bass seems to drown everything else out so much so that i can't focus on lyricism in hip hop as well anymore (i listen to hip hop primarily) but they are definitely fun. i was thinking the 558 foam modded/598 would be like an intermediate so i could still get some bass/feel it but properly listen to my library.
the dt770 are a little out of my range and i dont have a Xonar anymore for virtual surround anyway so ill have to onboard stereo them but regardless i dont want the same competitive shortcomings the xb500 (almost no sense of position/staging etc) are giving me. i feel like the bloated bass would cause these same problems
it also seems like id have to get to buying two completely different headphones instead of looking for the perfect compromise (which i thought the Senns would be lol)
You can get other sennheiser headphones like the hd439 that have a bit of everything..good for all music and gaming!
