"Seesaw" innovates the way of taking out and storing earphones, and its design is inspired by the seesaw in the children's park. The seesaw is one of the most popular amusement facilities in childhood. We refer to the structure of the seesaw and use the interactive behavior of pressing and rotating to evoke people's intuitive and interesting memories of playing the seesaw as a child, and at the same time complete the earphone taking and charging functions. In terms of design, it adopts the shape of hyperboloid buckle, creates a new visual symbol of the product, and designs a form with differentiation and memory. We cleverly use braille as a non-slip texture on the headset, so that visually impaired people can easily judge the left and right of the headset. At the same time, the magnets on the left and right earphones repel each other, so they will not be misplaced when storing the earphones. Technically, it supports dual microphone noise reduction and APP control to meet the individual needs of most users.
