Expensive headphones get into art territory at a point, but for the ears. When you can’t find the sound that a pair of headphones makes, but that signature nonetheless resonates with you in a meaningful way, it becomes something you would spend a lot of money to have in your life.
He is right. The HD800S is really not worth that much money for their capabilities or balanced signature (there’s little bass extension).
It’s worth it only if the person wants it that badly. If you don’t love them that much, if you can find the neutrality of the 600 series more pleasing, then you’re fortunate to have such a better value proposition and be at peace with it.
I have the 650 and I would never consider selling my 800S just because the 650 is a better value proposition. Sure it is, but it doesn’t have what I love about the 800S.
