Well shit... I need to make some funds to buy more books and practice exams. why are these tests so damn expensive lol... JAR modded HD600 is only a couple weeks old in mint condition. Everything is fresh and new. I've even swapped the headband foam to the 650 one because I prefer the aesthetics of it. I'll sweeten the pot by adding a set of balanced cables from Impact Audio since I won't be using it. (I'll still include the stock HD650 cable w/ 1/4" termination) I'm asking $350 for Friends and contributors. $375 for everyone else (Shipping and paypal all included) It's $450 for a new pair.
