The best iPhone amplifiers - with no electronics whatsoever

iPhone amplifiersThey are amplifiers and they are in the Gadgets section yet they have no electronics, need no batteries and do their job in a great way. Passive amplifiers are a fantastic example of what an engineer's mind can make. And they look great, too.


iBambooiBamboo is an electricity-free speaker made from a single piece of bamboo. The natural resonance of the bamboo amplifies the sound produced by the built-in speaker in the iPhone. iBamboo is 100% eco-friendly, efficient to manufacture, and produces little waste. Since bamboo is a natural material, no two iBamboos are alike. Every piece has the same functional parameters, but each one is unique in its appearance and beauty. As an added benefit, iBamboo improves a feng-shui feeling.

Natural AcousticsThe Natural Acoustics iPhone Amplifier is a passive ceramic amplifier made in Italy that produces naturally resonant tones from an iPhone. It is deesigned in Milan so it looks more like a sculpture than a gadget in a usual sense. The clay comes from the Tuscan comune of Montelupo Fiorentino, a prominent center of ceramics production during the Renaissance. The amplifier projects music or phone calls using authentic horn acoustics; simply place an iPhone in the amplifier's cradle. Its walnut base provides minimum contact with the horn for optimal acoustic performance.

KoostikThe Original Koostik is the result of a year of design and it is used in more than countries. By combining two hemispherical sound amplification chambers with carefully designed sound channels, it achieves natural energy free amplification of between 10 and 20 decibels (for you less technically inclined, that This means an increase of 2 to 4 times the volume). Due to it's unique design, the Original does not allow for the connection of your charger while in use with your iPhone, so it is a totally unplugged amplifier.
