For children's earphones, the main reasons that affect children's hearing are the sound quality of the earphones, the length of time they use the earphones, and the volume. But most of the children's headphones on the market are modified from adult headphones. However, after all, there are differences in hearing between adults and children. Therefore, long-term use of such headphones will adversely affect children's hearing. Since the quality of sound is related to the quality of headphones, we only need to buy good quality headphones for children. But on the premise of the same quality of headphones, in the process of children using headphones, how can we more intuitively know the time when children actually use headphones and the volume when they use headphones? To solve this problem, I designed this concept children's headphones.
