Koostik Original Handmade Eco Friendly Wooden Dock
Posted October 14, 2014 at 4:49pm by
The Original Koostik is the result of a year of product evolutionary design and refinement. It is a 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!
