So what do you do with an Altoids container once you are done with it? You turn it into a speaker of course. Ampoids offers up converted Altoids tin containers and converts them into working Amps or MP3 speakers. The tin easily fits in your pocket for easy travel and makes a really cool accessory for showing off. The Altoids MP3 Player AMP retails for $30 on Etsy and is powered by a 9V battery. It has an extra retro feel of turning on and off with a toggle. The speaker will work with newer iPod’s, the iPod Touch, and the iPhone.
