Hey guys i just joined head fi and was wondering what a suitable upgrade would be for my xb500's.
I love the bass in them but the treble is really lacking, and i was thinking the ultrasone hfi 580's would be a good enough upgrade as people say they have really 'full' bass and the treble isnt terrible either.
i wanted to check here first to see what you guys thought, and maybe get some more suggestions?
