Children's headphones have small ear cups and are often colorful. The cheerful exterior is most important for the kids, of course. As a parent, you're more concerned about your child's hearing. Children's headphones are limited to prevent hearing damage. Be careful, because if your child listens to music at maximum volume for long periods of time, it can still be harmful. Choose fully wireless headphones if you don't want your child to be bothered by a cable.
