Are you tired of always having to recharge or replace batteries in your iPhone’s external speakers? The Ambrosia Maple Original Koostik doesn’t have batteries; it passively amplifies your music. Koostik says by “combining two hemispherical sound amplification chambers with carefully designed sound channels, it achieves natural energy free amplification of between 10 and 20 decibels.” Although it will fit any model of the iPhone, the speaker’s design doesn’t allow you to use the charging cable while the phone sits in the speakers. It’s available for $95 from Koostik.
