This boom box has everything you’d expect in a portable stereo: an amplifier, speakers, even an iPod dock. But this one is made out of cardboard.
While most portable stereos aren’t particularly waterproof, this one doesn’t stand a chance in a rainstorm. The Mini Cardboard Boom Box comes folded flat and ready for assembly. It runs on two AA batteries, and connects to any MP3 player with a standard 3.5mm stereo jack. But it looks best with an iPod sitting in its “dock.”
