The epitome of minimalist, eco-friendly speakers, the iBamboo is literally just a piece of bamboo with an iPhone-sized hole cut in the top. Best of all? It really works!

For those who want to take their speaker outside and don't want to worry about warping or other damage from the elements, there is now the iBamboo Urban, made of recycled plastic instead of bamboo.
