This Phonofone works on passive amplification and can produce very nice resonant music by just placing your ear buds on its console (as shown in the picture). Isn’t it amazing now listen to this, it doesn’t even use any external power source or batteries. Now you might be wondering how does it work, the Phonofone uses horn acoustics to boost the audio output of standard earphones to up to 55 decibels* which roughly equals your laptop’s maximum volume.
Phonofone is totally made of ceramics because they are rigid and resonant and that’s why they are perfect for such an application, these are designed at ceramic fabrication facility in Toronto, Canada and the best part is they look awesome. They can lend a good look to your side table and can give you utterly soothing sound experience.
