Holua - 18Hz - 20KHz
From the mangroves of Madagascar to the Cloud Forest of Costa Rica, wood is all around us. Wood sounds good; we use it to make xylophones, drum sticks, claves and castanets. It's even in clarinets, for crying out loud. If headphones had been used a thousand years ago they would have been wood. Holua are made of wood, and they sound good...really good.
