Koostik makes zero-electricity, travel-ready solid wood iPhone and iPad music docks that offer natural acoustic amplification thanks to specially designed sound chambers and channels (similar to how a violin or guitar works). The company was founded by Jim Simon, who got the idea for Koostik while he was experimenting with using a megaphone to passively amplify the volume of his iPhone’s built-in speaker. With the power to create a sound boost of two to four times, Koostik’s energy efficient speakers give your music the perfect amount of mid-volume kick.
