Koostic: Acoustic, Power-Free Dock for the iPhone

Tweet

Wood has traditionally been the material of choice for speakers, particularly speaker membranes from expensive, exquisite brands for audiophiles. What better material to make an iPhone dock, then, than from wood? Even better: it doesn’t require any electricity.

The Koostic is a dock for the iPhone that requires no power. The dock works pretty much like an acoustic guitar, resonating the audio from the iPhone’s own speakers through its wooden body, thus amplifying the sound two to four times louder.

The Koostic has hemispherical sound chambers that amplify sound naturally, so you won’t have to worry about the usual noise and line noise that sometimes come with amplifying audio electronically.

The Koostic is a great gift to iPhone users who also love the feel of wood. The Koostic comes in various combinations of wood, such as cherry, walnut, and maple. The dock costs $90, and you can request customized combinations of different kinds of wood.
