The 580s/600s/650s are open cans and will give a more open sound that closed cans and iems can't replicate but the IE 80s really give this a go! With dense orchestral passages the 80s can't get close to what the others do. Those open cans also give a better sense of depth for this genre. But for virtually everything else the IE 80s compete very well and in many modern genres just blow the 580s et al away. I love using my IE 80s with chamber music where I can place each musician in an exact spot. I can also hear the timbre of their instrument so wonderfully.
The most amazing thing the IE80s have done for me is rekindle my interest in the latest music. I am currently listening to the Billboard Top 100 on Spotify and already have some new favourite musos including Will.i am, Macklemore, Deadmau5, Armin van Buren, Lorde, and I'm almost at pensionable age. The IE80s have just made this music so accessible to me, something my HD580s couldn't do.
