I am a rock fan, & I never felt any of the headphones I owned were good enough, so i decided I might invest 200 to 250 $ in some of those big over ear audiophile quality headphones. I'm looking for something with decent bass, not too much treble, & with as separate as possible sounds for different instruments, & least possible humming, cuz i usually hear humming where many ppl dont. Any suggestions, please?!!
