BoomCases: self-powered amps built into old suitcases

Mr Simo's BoomCases are self-powered amplification systems built into vintage suitcases and briefcases. They run for seven hours on a single charge, and come with a built-in charging plug. Cost is $275 and up, which is steep, but here's a way to be stylish and audiophilic in one go, and they're hand-made by a skilled craftsman besides.
