The Kensington Accessory Adapter adds a dock connector port to your iPod Shuffle, but it's not perfect.
Quick Take: Does your dock connector-free Apple iPod Shuffle feel left out when it comes to the wide world of iPod accessories? Show your Shuffle some iPod add-on love with the Kensington's Accessory Adapter ($20), a small ice-white module with a USB port for your iPod Shuffle on one end and a dock connector on the other. The adapter is perfect for plugging your Shuffle into speakers, FM transmitters, and other accessories that require a dock connector. Unfortunately, it won't send commands to the Shuffle as some iPod add-ons are designed to do.
