Shufflephones 2.0
Photo_Designer writes "After hacking my first pair of headphones to accept an iPod Shuffle, I just couldn't keep my hands off my other set of headphones and hacked an iPod shuffle adapter inside them, too. This version also includes an all-new expansion jack which allows sharing your music on the go, plugging your Shuffle into a stereo with a patch cable (without removing it from the phones), and also allows the headphones to be used as regular phones with the shuffle removed or turned off."
.. this hack is neither stylish nor functional, you can't really be a Mac user.. shame on your iPod!
