The Cork is an innovative Bluetooth speaker that boosts sound depth and quality by being placed on a bottle. With the bottle serving as resonance body, this speaker sets itself apart from other micro speakers that sacrifice sound quality in favour of a smaller construction size. The design of the speaker is reminiscent of a wine cork, alluding to its functionality. A washable silicon ring, supplied in two different sizes, serves as connection to the bottle. Moreover, the reutilisation of a used object stands for sustainability.
