I sold my 60D long ago so I no longer need this helpful Sescom cable. The cable allows you to use the USB AV port to monitor your audio with headphones when used in tandem with the Magic Lantern firmware. If you're shooting with a Canon 60D or T2i and have lamented not being able to monitor the recording, this cable will be a godsend. I used it maybe once or twice. Looking for $30. shipped and paypal in the ConUS. B&H sells it for $45. and it retails for $50.
