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.

Parental Control with Customizable Volume & Playtime

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.

Fit for kids

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.
