Upgrade cable for Senn 600s??

Its plug'n'play. No soldering required. Just unplug the old cable at the earpieces and slip the new ones in. The plugs are asymmetric, but not obviously so, so just be careful you match the pins correctly, and plug the red one into the right side of the cans. If you can't find one here, try headfi.com. The usually pop up used at least once a week. Not only Cardas, but Moon Audio and StefanARts. The Clou Red is also an upgrade, but not as good as the others.

Stefan Audioarts cables are well worth the wait!

Second Stefan Audioart Equinox cable. You just pop them in!
