QUBI earable is developed for improved listening in specific situations. It is known that many people have issues with listening and understanding speech in certain environments, for instance, during meetings, at a reception or in a restaurant. QUBI earable is the invisible solution to help with this problem. During the development of QUBI, the main focus has been on customer experience, design and usability, resulting in the SmartCase as an integral part of usability and the use of AirTap technology for switching between listening programs. The small design makes QUBI invisible to wear while creating the look and feel of a high-tech gadget.
