Here’s a pretty neat idea that’s in the works (not by me):
Tembo Trunks are the speakers that aren’t speakers. They are the first collapsible earbud speakers for iPods and iPhones.
All you need to do is attach your Apple earbuds to Tembo Trunks in order to transform them into a set of portable, non-electrical, virtually indestructible stereo speakers. Amplify your tunes. Anywhere. Anytime.
