Great Sound – Safe Volume The JBL Junior 470NC wireless over-ear headphones with noise-cancelling feature a new generation of JBL sound with a volume level that is safe for children's ears. The volume does not exceed 85 dB to protect young ears from harmful noise levels. Additionally, it includes active noise-cancelling, ensuring that a loud environment does not encourage children to raise the volume. You can use the JBL Headphones app to adjust the maximum volume and daily listening time or receive daily or weekly reports on your child's listening habits. The JBL Junior 470NC is designed for kids and offers high comfort. It features sturdy, large controls that are easy for even the smallest hands to use. With up to 50 hours of battery life, it provides long-lasting listening enjoyment, and an integrated microphone allows children to easily chat with family, friends, or teachers. The headphones are available in three cheerful colors and come with a JBL sticker set so your little rock stars can personalize their look. Great sound knows no age.
