The Quincy line is comprised of 3 models. The in-ear and on-ear models will likely comprise 80%+ of sales, due to price and size and they'll obviously work great. Quincy Jones isn't exactly the hot name in the 15-22 yr old demographic, so I think they are simply trying to give some good product a little more exposure, not to lure the $20 Skullcandy buyer. I have a bigger problem with K701 being sold at the online Apple store than this - it is obviously not a great match with a macbook.
I think anyone interested in the Q701 $399ish big headphones will want genuinely good sound and will be likely to buy a headphone amp if reccommended to when they purchase this model.
Quincy Jones has already been using AKG for years, so I hope they sell a ton, some money goes to Quincy Jones' charity and people end up with nice sounding gear.
I, too, would also like to see a new $400-$700 model that is even better, but these things take time. I'd be shocked if they weren't working on it.
