What does artificial treble sound like? I mean all IEM's are a processed sound so other than simply saying "un-natural", not sure I understand? I hear this thrown out a lot about W3 and how W4 has much better more natural sounding treble. But to me a heavy softness or veil (the way I hear W4) in the treble is far from natural as well.
ER4 is supposedly king of treble but sounds COMPLETELY different than W4. So which is more natural? Does accurate = natural?
