Bamboo sounds like a great idea for the music industry. It’s cheap, sustainable, and a great way to amplify vibration. Just take a look at the cheekily-named “loudbasstard“, a zero energy amp made for iPhones, iTouch, and later version Android smartphones. Created by Koh Onozawa and Franz Ignacio, each pair is cut and dyed by hand in Cebu Philippines. Both a way to promote environmentally friendly design and empower the Philippine community, the loudbasstard takes advantage of native craftsmanship and materials to project your favorite tunes.

A simpler, more rustic version of the node speaker is also available through ibamboo. Open at both ends, the cylinder creates a “pseudo-stereo” effect for Apple phones and devices. Rough-hewn and with a black or natural finish, the grass with its own carrying case and recyclable box. Originally began as a Kickstarter campaign, the product has been so successful that it has been featured in the New York Times and is temporarily out of stock.

On a similar note, the iBam 2 combines high quality bamboo with efficient design. With a waterproof carrying case and carved box, the speaker is a perfect low-tech device to take on beach trips or anywhere it might be difficult to find an outlet. As an added bonus, every purchase helps workers and the reforestation effort in Southeast Asia.
