Fegefeuer,
I was almost as blown away by your description as you must've felt hearing the headphone! I could feel your enthusiasm the entire time, as I read more my surprise mounted. I really hope it's worth the price, because here's the thing... save up enough, be dedicated enough, it's not that impossible to save up for.
One question I have: how's the wearing comfort? Many people applaud the HD800 comfort...
I can confirm that the HD800 is excellent in comfort, it feels wonderful. So if the K812 is just as comfortable that's saying a lot.
