This pair of cans does interest me....Have the senn hd650 but I miss a bit of the bass slam...Then there are the focal elear but they're much more $$_
different type of bass between EL8 and HD-650, EL8 is better sub-bass and less mid bass than HD-650 while HD-650 is more mid bass and almost no sub-bass, comes down to the music and your preferences.
