The eco-amp by Los Angeles-based company eco-made is an iPhone amplifier which eschews toxic plastics and a battery in favor of an environmentally friendly approach to portable amplification. Produced from 100 percent recycled paper, the eco-amp comes in a flat-pack and requires assembly on the part of the consumer.
Despite its name, the eco-amp really functions more like the horn from an old Gramophone player, as there’s no speaker cone or internal amplifier, just a cleverly folded piece of recycled paper which acts to increase the audible volume.
eco-made frankly confesses to holding unscientific listening tests when attempting to measure the eco-amp's amplification abilities, making use of an iPhone app to arrive at a suggested increase in perceptible volume of 30 dB. This is sure to leave audiophiles underwhelmed, but then your average audiophile probably isn't looking to amplify an iPhone in the first place.
The eco-amp is available for US$7.99 plus shipping, with each package containing two units. For more information on assembly, check out this instructional video from eco-made:
