Up for sale is my Sennheiser HD650 is very good condition. I don't see any scuffs or scratches on them. The pads are clean, but not as firm as a new pair, still very good though. The box/case is in ok/good condition(it's a box!), The cable is in good condition. And last but not least, I'll include a cheap 1/4" to 1/8" adapter(last picture).
$325 + $15 Shipping. Paypal gift or add 4% to cover the fees.
I also have a stock HD650 cable terminated to Balanced 4 pin XLR(Neutrik plug) for an additional $20 if your buying the Headphones.
