I have a pair of HD600 in excellent condition that I'd like to sell. These are several years old but are in excellent condition, low hours. They've only had about 15 hours of playback and are not even broken in yet.
I have two pair of HD600 and am going to keep my pair that's already broken in with several hundred hours. I'm going in another direction in building my second rig, hence the sale on these.
I can take some pictures this evening if there's interest. I have the original box and packaging and these will be shipped double boxed to withstand the worst that FedEx can throw at them.
