As the headline implies, after ordering the Sennheiser HD650 Cable, Headline Pad and Foam Net Pads as a replacement for my dead HD600s cable (RIP, it lasted 5 years of honorable work) I thought about switching the cards on the tables after doing some research and seeing how different the thickness and solidity of the HD650 cable is.
And I can confirm every single thing I heard and saw, this is probably the best cable I ever got (probably would be even better in a balanced output form but we go high end there), so if you have a compatible Sennheiser series, trust it, this won't let you down.
Full stars.
