Tembo Trunks earbud speakers need no power to work their magic

Tembo Trunks earbud speakers are like passive amplifiers to those tiny earbuds. And boy, do these things amplify music… According to designers Mike and Scott Norrie the rubber speakers work as horn-speakers, pulling out sound from the tiny earbuds to something like 80dB. That would be loud enough for any respectable speakers. Since these are made from rubber, they are easy to carry around and are virtually indestructible. If you like the idea, you can back the project on Kickstarter.
