The Cuby is rather a chic little dock from Princeton Japan for your Second-Gen Shuffle. Compact and bijou, you can power it up via USB or with 3 AA batteries. Measuring 49 x 49x 59 mm and weighing 95 grams, it delivers sound from its 0.5W x 2Ch speakers and you can get it for $33 in Japan. See it undressed below.
