I don't know what "real" memory foam is like.
I just know that when you press down on this stuff is takes awhile for it to come back to it's original shape.
You can compress it down to nothing and it will slowly expand back. It's definitely not hard at all.
I bet AKG could come up with an over-stuffed pad that had as much depth as the Q701 pads when compressed.
They could maybe use a combination of different types of foams inside.
I want an HD-650 killer!!
Maybe AKG could experiment with the harder memory foam that doesn't compress as much.
Some memory foam seems to turn into a brick during winter. I wonder if the Annie pads will? Doubt it.
