Passive amplification for your personal music player (ipod, mp3) has never been better integrated in your house design. Tristan Zimmermann is the designer of the “Phonofone II”. The phonofone is made completely from ceramic. Passive amplification means that the phonofone doesn’t use external power or batteries. The phonofone creatively exploits the qualities of horn acoustics to amplify the audio output of standard earphones to up to 55 decibels!
The phonofone will be available from April, for now you can just place a preorder here.
