Griffin Technology has unveiled a new accessory that makes Apple's second-generation iPod shuffle work with any device that features a Universal Dock. The new Dock Adapter enables iPod shuffle owners to use speaker systems as well as other devices that were previously accessible only to full-size docking iPods, serving as a low profile device that fits in most travel accessory cases. The adapter features a slider switch that toggles between charge/sync and audio play modes, allowing the docked Shuffle to transfer data and sync with iTunes while charging the battery. In play mode the iPod shuffle outputs its audio to any connected speaker system. Griffin's Dock Adapter for iPod shuffle is available for $20, and works with Apple's second-generation iPod shuffle models.
