Once upon a time, King Sony said to his people, "There shall be a new flagship, and she will be crafted of the finest wood of the land. We will fly her sails of bio-cellulose high, and those who ride her will be comforted by the soft touch of lambskin upon them. And we shall call her... the MDR-R10."
Unfortunately, only but a few of the king's people could afford the $4000 pricetag that this flagship from a bygone era demanded. But fortunately the king has learned from the err of his ways, and a new, sleek, incredibly comfortable flagship with improved technology can be enjoyed by all. And we shall call her... the MDR-Z7.
