The rise of Apple and their iPhone over the last few years has led to a stampede of savvy designers and businesses launching onto the market tons of apps and numerous types of phone accessories. However standing out from the crowd is design team, en&is's Passive Amplifier system. What makes this product so different is the low tech approach taken. This ceramic amplifier relies on no wires, plugs, electricity or headphones just the simple laws of sound. Definitely a cool way to listen to music or hold that conference call.
