I had those headphones , the ether flows open , i have to say that they are great. Unfortunately to my taste, there are too crispy, too bright on the heighs , it was too much for me. And i m not for the dark sounds , absoulutely not. But for those headphones, at this price range, they should be able to make them smoother and bringing some more precision. I have to say i came from the HD800S, i ve had for several months, great cans, but ...too thin for my taste. If Mrspeakers would find a solution for the crispy sound, then, we can say that they will become the number ones , as far as i m concerned. I heard that the closed back are phenomenal, maybe it would be suitable to go on that direction.
