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. It's specially engineered inner sound tunnel and rings increase music volume by %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.
