YoYo mp3 / MP3

YoYo mp3

After using mp3, we often roll the earphone line around the mp3. Yoyo mp3 is made for the concept of yoyo, which makes the rolling action interesting and fun. The earphone line is rolled around together such as the exact yoyo, and the user who tries to roll or unroll just need to treat it like playing with yoyo. In this way, the rolling or unrolling act itself is not annoying anymore, however, it provides a kind of fun. Considering the characteristics of yoyo having Reaction and physical force, we made the earphone line witha the dense fabric. And, the user just need to choose either listening to music or playing with yoyo.
