iBamboo is an electricity-free speaker made from a single piece of bamboo -- a natural material. The natural resonance of the bamboo amplifies the sound produced by the built-in speaker in the iPhone 4/4S, 5 and the iPhone 6. iBamboo is 100% eco-friendly, efficient to manufacture, and produces little waste. These speakers combine the high-tech of the modern day with the simplicity and aesthetics of nature. 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 the feng-shui of your desk or any other environment in which it finds itself.
