Product Description

This Original Koostik is the result of a year of product evolution and refinement. It is the company's first passive solid wood acoustic amplifier for iPhone, and this now iconic design is in daily use in over 30 countries. By combining two hemispherical sound amplification chambers with carefully designed sound channels, it achieves natural energy free amplification of between 10 and 20 decibels. This means an increase of 2 to 4 times the volume. Please note that due to its unique design, the Original does not allow for the connection of your charger while your iPhone is in use. It is a totally "unplugged" amplifier.
