Asthetics are all well and good. I'm all for having choices, but the excuse CNet uses for the color change is appliciable only in the pro arena - not in the audiophile world where the care for equipment is almost a religion. What color my headphones are is totally irrelavent given that I can't see them when I'm wearing them, so I wouldn't care if they were pink with purple polka-dots as long as they sound good and fit comfortably.
The only upgrade the K702s have over the K701s that affects audiophiles is the detachable cable. If you don't already have a pair of K701s, then I can see waiting for th K702s. Otherwise, why waste money that could be put to far better use?
Just my (adjusted for inflation) $2.
Oh, and as far as I know the price will be the same as the K701s - sonic quality too. Well, with the stock cable anyway. What a different cable will do to the sound is anyones guess.
