The Original Wooden Amplifier by Koostik is truly "unplugged" as it channels the music from an iPhone through a sculptural block of rich-grained black walnut, amplifying the sound by two to four times with no need for batteries or a power cord.
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!
The Original Koostik is compatible with all versions of the iPhone.
