The Phonofone is an audio amplification device which will play back music from earphones. You simply place earphones on it and it uses the properties of horn acoustics to play it back up to 55 decibles.
Through passive amplification alone, These unique pieces instantly transform any personal music player + earbuds into a sculptural audio console. Without the use of external power or batteries, the Phonofone inventively exploits the virtues of horn acoustics to boost the audio output of standard earphones to up to 55 decibles* (or roughly the maximum volume of laptop speakers) Upon connecting active earphones to the Phonofone their trebly buzzing is instantly and profoundly transformed into a warm, rich and resonant sound.
It's a neat idea, but why not just buy some speakers? They might not look as cool, but then you wouldn't have to carry around a ceramic phonograph all day. Plus this thing costs $830 so, you know, you'll probably have to sell your first born child to afford them.
