Koostik is the name of this beautiful amplifier for your iPhone, made entirely of wood, by hand. It will acoustically amplify the volume output on your phone by 2 to 4 times.
Think of a solid body guitar that’s unplugged-you strum the strings and get a little bit of sound. But if those strings are placed over a hollow body guitar and you strum the strings-you suddenly have acoustic music. The same principal is at work with Koostik. Simply place your iPhone into the center cradle, and immediately you hear your music acoustically amplified!
Here is a video showing the Koostik iPhone amplifier in action:
The Koostik is designed so it works with all generations of iPhone. All of the external buttons and controls of the phone are easily accessible while the phone is docked in the Koostik.
The Koostik iPhone Amplifier is offered in a wide range of different types of wood including maple. Depending on which you choose, the prices range from $85 to $90.
