There are some buttons on the Surface Matters Speaker, but you might not notice them right away; they're hidden under an elastic fabric overlay and remain invisible until you wish to interact with the device. What you'll first see is a minimalist round sound system with a soft face, a rounded shell and absolutely no visual fuss.
Press in the center of the tactile control interface and the the concealed buttons will illuminate. To activate them, you can either press them directly or gently poke the stretchy material just beside them. Eun Hee Jo's cutting-edge concept allows you to adjust the volume with tactile swiping gestures; scroll through your music collection by drawing a circular pattern over the Surface Matters Speaker.
