Received my hybrid and velour pads today. Haven't had the chance to A-B them but I really like the feel of the hybrid pads. I don't know if the sound has changed, but I certainly don't think it's gotten any worse.
So...I got my HE-400s in last week.
Favorite headphone. Without question.
My HD 600s are great for when I want to relax to some jazz or classical but for everything else, the HE-400s are going on my head. Love these things.
