The German Design Award 2018 winning Wooden Sound System works with any smartphone, is crafted entirely out of wood, and doesn’t need electricity or special connections. Its specially engineered inner sound tunnel and rings increase music volume by 25 dB - a perceived increase of %400. The unique acoustical properties of birchwood deliver a warmer tone, smoother highs, and more prominent bass. It tends to be a great gifting piece, with a limited-edition screen-printed cloth package that looks beautiful on a shelf. Made in Turkey. Ships from USA. 6.8" l x 3.9" w x 1.7" h
