This is a clip-on bluetooth earphone. It is detachable, so you can use it with other earphones. When I designed this, the most important part was the form that felt a sense of unity. The clip attached to this product is functionally very useful. However, this element makes the image of the product coarse. I wanted this to be expressed in one chunk. I used the solid and smooth shape of the killer whale as the motif for this product. The button is located on the front of the product. The button is visually very intuitive, and you can tell which button it is by touch.
