Planet Buddies wireless headphones are volume limited to 85 decibels which is the level recommended for kids by the World Health Organization (WHO). The child-safe audio limit on our headphones helps to prevent noise-induced hearing loss. Listening at a maximum level of 85 decibels makes it safe to enjoy up to 8 hours of audio a day and is suitable for children aged 3+. With their comfortable earpads, adjustable headband, and an impressive play time of up to 38 hours, our headphones are the perfect music companion. Our smart music sharing feature means you can connect a second pair of headphones and share your audio with your best friend! Compatible with any Bluetooth device, they also come with an 80cm Type-C charging cable and 150cm AUX-in cable, so you can continue to listen whilst charging. They also feature a built-in microphone for singing, phone calls or talking with friends. Our wireless headphones are designed with adventure in mind: foldable, lightweight and portable, we've even included a carry pouch so your little one can enjoy their on-ear wireless headphones wherever you go exploring. Planet Buddies wireless headphones are made of 50% recycled plastics.
