Safe JBL Sound <85dB

The protection of children's hearing is non-negotiable. The JBL Junior 320BT is tuned so that the volume never exceeds 85dB, ensuring that young listeners enjoy crystal-clear sound without the risk of exposure to dangerous noise levels. It is the ideal solution for children to get in touch with music and multimedia content, keeping their ear health as a top priority.

Advanced Parental Control via App

Through the JBL Headphones app, parents have complete control over the listening experience. You can set a personalized volume limit even lower than 85dB, restrict the daily usage time, and receive detailed reports on your children's habits. By using a PIN code, your settings remain secure, giving you peace of mind while your children explore the world of sound.

50 Hours Battery Life & Fast Charging

Play and learning never stop with a battery that lasts up to 50 hours on a single charge. If you forget to charge them, the fast charging function via USB-C offers 3 additional hours of use with just 5 minutes of charging. This exceptional battery life makes the Junior 320BT ideal for long trips, school activities, or multi-day use without the worry of searching for a charger.

Ergonomic Design & Ultimate Comfort

The headphones are designed for children's bodies, featuring a soft 12mm padding on the headband for comfort during extended use. The adjustable design allows the headphones to "grow" with the child, ensuring a perfect fit and minimal sound leakage. Additionally, the foldable design (fold flat) makes them extremely easy to carry, as they fit comfortably in any school bag or backpack.

Type
On Ear

Type

On Ear

Headphones with smaller ear cups compared to over-ear headphones, which sit on the ears.

They are more portable due to their smaller size, but offer less comfort and isolation from external noise.

Generally, over-ear headphones, thanks to their larger speakers, can offer better sound quality and deep bass compared to on-ear headphones of similar quality.
Frequency Response
20 - 20000 Hz

Frequency Response

The range of frequencies that headphones can reproduce. The most common range is that of human hearing, 20 - 20000 Hz. A wider frequency range does not necessarily mean better sound quality.

  • (Bass) 20-250 Hz: Stronger bass, for depth. Ideal frequencies for listening to electronic or hip hop music.
  • (Mids) 250-4,000 Hz: The mid frequencies are stronger, suitable for better listening to vocals or orchestral music.
  • (Treble) 4,000-20,000 Hz: High frequencies affect the clarity and sharpness of the sound, for better listening to, for example, cymbals or the plucking of classical guitar strings.
Impendance
34 ohm

Impendance

The resistance that the speakers of headphones have to electric current. Usually, the lower the resistance, the louder the headphones sound, but the sound is less clear.

This size does not concern the average user as almost all headphones are 32 Ohms. Headphones with high resistance usually require an additional amplifier.
Sensitivity
85 dB

Sensitivity

The greater the sensitivity of the headphones, the louder they will sound at a specific volume of the source. Generally, values above 90db are considered very good. - **Above 100db**: Headphones with high Sensitivity produce more sound with less power. They can reach high volumes with low-power devices (e.g., mobile phone, laptop). - **Below 100db**: Headphones with low Sensitivity require more power to reach the same volume levels, so they may need a special headphone amplifier
Driver Diameter
32 mm

Driver Diameter

The diameter of the headphones' speakers. Usually, the larger the diameter, the more powerful sound with full bass they can offer.
