Rechargeable USB card speaker

It works great with a notebook as well, and since it comes in the size of a credit card, it gets fidelity which is worth every penny. This is a product from I.D.E.A. of Japan, where it comes with a heavyweight metal construction that stands up to travel abuse, and boasts a 5 hour battery life (it takes 2 hours for a full charge via USB). It will play nice with any device as long as it uses a 3.5mm connection, where you can choose from Matte Gold, Shiny Black and Stainless finish at $74 a pop.
