Designers Enrico Bosa and Isabella Lovero of Italian studio en&is created MegaPhone, a powerless iPhone amplifier. The piece consists of a sleek ceramic horn, supported by a wooden structure. This frame elevates the object from the surface and increases its vibration. The shape of the ceramic piece optimizes the emission of sound. That simple.

Perfect for listening to music without headphones and conference calls, MegaPhone works beautifully with the shape of the device. And its minimal design fully supports Steve Jobs' noble war on buttons.

The MegaPhone is now available for purchase on RedEnvelope.
