Overview
The JBL Junior 320 is a wired, volume-limited on-ear headphone for kids, built with JBL Safe Sound to cap output at 85dB, alongside a padded headband, a built-in mic and a foldable frame for school and travel.
- JBL Safe Sound caps volume at 85dB
- Built-in mic for calls without extra gear
- 12mm padded headband for long wear
- Customizable stickers included
Who it's for
Parents buying a first headphone for a school-age child who want a hard volume cap built in. Less suited to kids under 6, per one owner's account of the ear sleeves coming loose too easily.
What buyers say
From Amazon customer reviews.
Parents and grandparents praised the fit and sound quality across kids aged 2 to 7 and liked the peace of mind from the volume cap, with one buyer calling the build quality solid for younger kids specifically. Complaints included stickers that don't stick well, an included adapter that doesn't fit every device, and one report that the ear sleeves slide off too easily for children under 6.
Strengths and trade-offs

Performance notes
