American Cherry is a highly prized hardwood known for it’s beautiful pinkish-red coloration which mellows to a deep warm amber tone over time. It is relatively hard and thus finishes to a very smooth surface feel. Cherry has occasional “pith marks” which are small darker spots or streaks that run randomly throughout the tree. These are natural characteristics in the wood and we make no attempt to eliminate or disguise these features.
The Original Koostik is the result of a year of product evolutionary design and refinement. It is our 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 it's unique design, the Original does not allow for the connection of your charger while in use with your iPhone. It is a totally "unplugged" amplifier!
The Original Koostik is compatible with all versions of the iPhone.
