It's fairly easy to be subjective about frequency response between two headphones, actually. I mean not long ago, bobbyblack and I disagreed about the bass on the HE-6. He said it had lighter bass than the HE-500, to which I 100% disagree. At first I figured he may have just heard the headphones under-amped, which does alter the sound significantly. Then I found out he hasn't actually heard the headphones, which makes more sense. He firmly believes the HE-6's bass is lighter even though he hasn't heard it himself. I'd be willing to bet that when he does get the chance to listen to the HE-6, he will come away from that experience feeling that the HE-6 does indeed have lighter bass - that's where the expectation bias comes in.
But yeah, there are also cases where people universally agree, such as how the HE-6 is a bit brighter than the HE-500. Regardless, you never fully know what a headphone is like 'til you try it yourself. Maybe the HE-6 really does have lighter bass. Maybe it doesn't. Only one way to find out.[/QUO
