Bamboombox Natural Three Ridges

We think these are ingenious -- a simple, yet beautifully crafted piece of eco-friendly bamboo that amplifies the sound from your iPhone to two or three times the original volume.

Bamboombox adds depth, bass and atmosphere to the music played, transforming the tinny sound from the phone. There aren't any tricky electrical components to go wrong and it’s resilient, even if it were to fall off the shelf or if you decide to take it with you in your bag.
