Phonofone II is now available in black(!).
“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 II inventively exploits the virtues of horn acoustics to boost the audio output of standard earphones to up to 55 decibels.”
