Well, if you wanna put it negatively, I guess you can sort of seeing those kinds of tradeoffs, but if youre being negative, the HE4 is thinner, colder, harsher, and less euphonic than the HE500..
Its purely based on preferences. You either want the speed and air of the 4, or the musicality, warmth and organic tone of the 500.
Basically, LCD2 vs HE6?
Ahhhh. the 500 has no speed and air.....I think someone said the HE-560 has that! Maybe the HE-4 is just more neutral than the 500?
