Wood Smartphone Sound Amplifier

This German Design Award winning amplifier leverages wood's natural acoustic properties and intelligent design to deliver a 25 dB boost - four times louder - entirely through passive engineering. No batteries, no cables, no clutter. 

Handmade from birch wood, its precisely designed inner chamber and 7 layers of cut rings amplifies sound while also enriching it, delivering warmly resonant notes with smoother highs and a fuller bass. 

It won the German Design Award for good reason: it seamlessly combines solid acoustic engineering with a clean, minimal design that works in any space, using sustainable birch wood.

The universal design fits all smartphone models.
