I bought this cable from ebay about 2 weeks ago.
I'm selling of my hd600s so I no longer need this cable.
6 foot Canare L-4E6S cable.
1/4" gold plated connector, soft woven cable cover, Cardas HPSC connector for Sennheiser headphones.
Made with Cardas Quad solder and well reinforced joints.
Price includes Paypal and shipping fees.
