Children who can not remove headphones

There was a young boy and mother wearing headphones in the train. People around me told my mother, "Do not listen to music with headphones! But the boy was not listening to music. On the contrary, when it hears the sound, it may be unbearable, so we declined the sound as much as possible. Boys still have few people to know, so it was often misunderstood "hypersensitivity".
