The first Koostik was a styrofoam coffee cup with a slot cut in the bottom to receive the iPhone 3GS. The result was a simple megaphone to amplify the volume from the external iPhone’s speaker. From that humble beginning, dozens of prototypes in wood followed. We tinkered for several months in our garage workshop creating variations of that first idea; trying to come up with the right combination of form and functionality. After several months, we hit on the design of the Original Koostik.
It worked beautifully, and it was pleasing to look at and to hold. It has become iconic among all the plastic and silicone attempts at natural acoustic amplification for smart phones; so iconic in fact, that it is now in use by thousands of people in over 45 countries around the world.
