We mainly listen to music or enjoy content with our earphones. In recent years, wireless earphones that allow users to enjoy content without restrictions in various usage environments have appeared and gaining popularity. Until now, earphones are designed for the definitive purpose of being able to listen to music/content, just as an electronic product that can be plugged into your ear. However, wireless earphones go beyond just viewing content and have new possibilities, such as AI assistants, augmented sound, ambient sensing and hearing aids. As earphones used for simple listening to music are converted to 'hearable devices', a new design perspective is needed. It is important that you don't feel any visual/physical discomfort when wearing your earphones and doing everyday activities or having conversations. We researched a variety of ear shape and skin tone options and tried to find shapes and colors that match neutrally. We extracted the character line by overlapping various ear shapes and defined a neutral skin color that suits various skin tones and tones.
