Phonofone III by Tristan Zimmermann

The latest addition to the Phonofone family, this passive amplifier is designed specifically for the iPhone.

The Phonofone III is a passive amplifier crafted from ceramic and handmade in Canada. This elegant device amplifies the volume emitted from an iPhone internal speaker to be roughly four times louder, or approximately 60 decibels. iPhone, of course, not included.
