I don't like the HD650's at all, they lack bass definition, prat and they sound closed-in compared to the best. I consider them a good gateway phone for beginners used to low end bass boosted junk. Their saving grace is the tonal balance for people that love bass and hate treble.
Now, get a meier concerto or a lehmann black cube linear and learn how the HD650 should sound.
