Have you ever been in a situation where you wanted to share the music on your iPod with your friends, but the teeny speakers on the device didn’t do the sound much justice? Well, two designers from Sydney, Australia have come up with a solution to the problem. Called the Trembo Trunks, these useful rubber “speakers” help you to amplify sounds coming out of your regular earphone buds wherever you are. Lightweight, highly durable and requiring no power, all you have to do is plug your headphones into the speakers and hit play on your iPod. The Trembo Trunks have been designed in such a way that any sound played through the headphones are amplified (up to 80dB) so your music can be heard by more than one person. Since they can be placed any way you want, you can get stereo sounds coming out of these babies. The product is currently seeking funds on Kickstarter, and it has already met its goal, but if you’re interested in getting your hands on a set before anyone else, head to the site to find out more.
