Trobla Wooden Smartphone Amplifier
It's by no means the first passive phone amplifier we've seen. But it is the best looking. The Trobla Wooden Smartphone Amplifier works with a wide variety of devices, using a carefully-crafted series of canals and a horn-shaped opening in the wooden enclosure to both amplify the sound emerging from your phone and make it sound far better than it would if you're just ghetto blasting off a table or shelf. Available in maple or walnut.
