Toronto-based Science + Sons’ [Phonofone II](http://www.scienceandsons.com/ph2.php) is an ingenious little device that uses passive amplification to turn your personal music player’s earphones into full fledged speakers (or at least, laptop-sounding fledged speakers). In addition, by combining horn acoustics with the audio conductive properties of rigid ceramics, [Phonofone II](http://www.scienceandsons.com/ph2.php) requires no external power source or batteries. According to the designer, Phonofone II has been licensed by a ‘foreign design concern’ and is slated for commercial release in Spring 2008.
