Yes, of course it's a novelty, but there's no denying the appeal of this Retro Cassette Stereo Mini Speaker for iPod and iPhone.
Not just packing those 80s-style ghetto blasting looks, this iPod-friendly add-on takes power from your iPod, using it to knock out your tunes to a wider public. How loud? We don't know, but we suspect it's not going to annoy too many people on the morning bus.
Good for using with just about every generation of iPod and iPhone, you can pick it up online (in the US, at least) for $31.99.
