Gramo is easy to bend flat, which makes it easy to carry with you. When you turn elements out, speaker transforms to a table speaker. Design comes from the beginning when real records started to appear. It was gramophone - also as inspiration for the design. Gramo speaker holds 5 elements inside. Outside 3 toppest surfaces are also solar panels, which makes battery last longer when you’re enjoying fresh air and good company outside. Volume changes with soft touch of your finger.
