With summer approaching, many of us are searching for suitable iPhone speakers for portable tunes in the sun. The way we see it, there's no sense adding to the iPhone's already gargantuan environmental footprint by buying electronic speakers. This new product from L.A. startup eco-made is just the solution we've been waiting for. The eco-amp is a powerless iPhone amplifer made from 100% post-consumer recycled paper, which folds into a smart-looking cone that can be unfolded and packed flat for easy transportation. As you can see from this instructional vid on YouTube, the eco-amp delivers crisp and clear sound. And at only $7.99 for a set of two speakers, the price really can't be beat.
