Headphoneus Supremus
There're three switches for adjusting Low, Mid, High. Very fancy, if not too. Anyway, it's just a prototype.
Actually, you can try to get in touch with him using QQ. It's quite fun. He loves to send his friends photos of prototypes, which are different almost every month.
There're some friends here who talk with him quite often, as I know.
Where can I buy these right this very second?!?!?!
