From the website:

“Speakers for your iPod can be clunky affairs. They very rarely fit in your pocket, and we’re almost certain none of them look like a building block, even if they’re almost the same size. That is until now! The iBlocks have been cleverly modelled on one of our favourite childhood building blocks (you know the ones we mean) and are small enough to pop in your pocket, so there’s no need for extra cases or wires to clutter up your bag. The sound is pretty impressive for something so small, the Active Bass System makes sure the speakers give out quite a kick. All you need to do to get it working is to plug it in and we just love the volume control buttons that have been camouflaged to look like ‘bumps’ and discreetly placed in the middle of the block. Compatible with 3rd Generation iPods onwards and the iPod Touch.”

They come in red, white, and black.  You can buy them here for £12.99
