Ripped this from the BulgingWallet... credit goes to Mjen... the hd600 go for about $230 on ebay... newegg had them for $250 at one point... by the way, there's a $15 off $200 coupon which you can find @ techbargains. Looks like it'll work without exactly $200 in your cart as well. And there are only 9 HD600s left, so hurry.

Pretty decent deals if you're down with spending money for quality cans.
I called them up. These are not refurbished items.
Lowest prices I've seen in a while on these two high end models from Sennheiser.
Shipping almost kills it though... still good.
