A wooden amplifier that enhances your phone's sound in style, without batteries or electronic components. Each Trobla comes with one adapter for your smartphone and a bag. 

Beautifully designed and artfully handmade in collaboration with local businesses and craftsmen using Slovenian wood and other locally sourced materials, the Trobla is here to elevate the sound of your smartphone speaker - with no electronics.

It may be small, but this easy-to-carry piece holds a mighty sound. An amplifier for smartphones, Trobla will set the mood wherever you go. There is no need to plug in or charge it to get top-quality audio, since the sound naturally travels through a hollowed chamber and is guided by a cone. No apps, no batteries, no nothing. All you need is your smartphone.
