Phonofone II by Tristan Zimmermann

Through passive amplification alone, you can turn any music player with earbuds into a sculptural audio console.

Phonofone II amplifies the output of standard earbuds up to 55 decibels, using horn acoustics to transform the ‘bud’s trebly buzz into a warm, rich sound. It’s constructed entirely from ceramic, which is environmentally low impact, inherently rigid, and resonant.
