From the Manufacturer
With the Griffin Dock Adapter for iPod shuffle you can finally use your iPod shuffle with your favorite full-size universal dock devices. Your iPod shuffle's incredible entertainment value has always been partially tied to its incredibly small size, but with this Dock Adapter it can now deliver music just like its full-sized iPod cousins.
Griffin's dock adapter is constructed with the same exact shape as the actual dock connectors on the bottom of every full-sized iPod. Easy to use, all you have to do is plug your iPod shuffle into this unit via its headphone jack, and then plug the adapter into your iPod speakers, in-vehicle adapter, or any other iPod docking accessory. This Griffin Dock Adapter is designed especially for your second-generation iPod shuffle, and is backed by a manufacturer's one-year warranty.
