Named Trobla after the Slovenian word for horn, this amplifier naturally boosts the sound of your favorite music and podcasts. The Tok Tok design is handmade from regional woods—walnut or maple—and naturally finished. Keeping up with the new, eco-friendly standard, the amplifier has no need for electricity but works with smartphones, increasing the volume and serving as a stand. Tok Tok’s handsome take is chambered and shaped like a cone so that it both delivers on sound and looks great. Lightweight yet durable, Trobla is also portable; you can take it anywhere in your bag and use it indoors or outside. The sustainable product is compatible with several iPhone and Samsung models, and the detachable adaptors can be easily interchanged in order to fit new generations and brands. Trobla is already successfully funded on Kickstarter, but it will keep kicking until Sunday, May 17, 2015. Pre-order the design for $65, or more when you add features such as personal engraving.
