Great sound—safe volume

JBL Junior 320BT wireless on-ear headphones introduce a whole new generation to JBL sound in a way that’s safe for their ears. They won’t go beyond 85dB, protecting young listeners from dangerous sound levels. Plus, you can use the JBL Headphones app to customize maximum volume and daily listening time, and get daily or weekly reports on your kids' listening habits. Designed for young kids, the JBL Junior 320BT are comfortable to wear, with durable oversized controls that are easy for even the littlest hands to use. 50 hours of battery life means long-lasting fun, and a built-in mic lets kids chat with family, friends, or teachers easily. They come in three fun colorways and include a JBL sticker set so your little rockstars can personalize their look. Great sound has no age limit.

JBL Junior 320BT headphones are designed to never exceed 85dB. This way your kids can enjoy the same great sound that made JBL a legend, at a volume that is always safe for their ears.
Use the automatic 85dB maximum volume limit, or customize a lower one. You can also customize hearing protection settings by limiting both maximum volume and daily listening time.
Use the JBL Headphones app for real-time reports on how long kids are listening and at what volume. Check daily and weekly usage and volume reports. And set up your own PIN code to protect your settings.
JBL Junior 320BT headphones feature a built-in microphone to help your kids stay connected with the world. They can talk with teachers while they're learning, or chat with friends and family during their downtime.
JBL Junior 320BT headphones offer a long 50-hour battery life and recharge quickly with user-friendly USB-C cables. For a super-quick boost, five minutes of charge will give you another three hours of battery life.
JBL Junior 320BT headphones come in three fun colorways and feature a 12mm thick soft pad on the headband for long-wearing comfort, less sound leakage and better sound. The headband can be adjusted to the kids' head to improve the sound experience and follow the kids' growth. JBL Junior 320BT headphones fold flat, making them easy for kids to stow in a bag or backpack.
Durable, child-friendly control buttons make JBL Junior 320BT headphones easy and safe for kids to operate.
The plastic-free packaging folds into a fun device stand, and a playful JBL sticker set is included so kids can personalize their headphones.
