Response from AKG on Facbook about the comments about the Q line.
"Good questions/comments everyone. To answer your questions on the what's unique about the new Quincy Signature Line, we'd like to let you know that Quincy Jones himself worked with us to design a headphone that made aesthetic changes to ref...lect more of his personal touch. The models come in black, white (with lime green accents) and a proprietary lime green color only available within the Signature Line. Also, the 330s and the 460s will feature an inline microphone that will work with mobile devices such as the iPhone and Blackberry and a remote control (only compatible with iPhones) to play, pause and skip through music so that people can still have a quality sound experience for lifestyles that are increasingly more mobile and on the go."
sooo it is just the looks....
