The JBL JR310BT are wireless on-ear headphones engineered specifically for children. A primary safety feature is the sound pressure level, which is limited to 80 dB to safeguard hearing during extended listening sessions. Audio is produced by 32mm dynamic drivers, covering a frequency response range of 20 Hz to 20,000 Hz. These headphones utilize Bluetooth 5.0 for a stable wireless connection to compatible devices, maintaining a signal for up to 15 meters.
The integrated lithium-ion polymer battery provides up to 30 hours of continuous audio playback and recharges completely in two hours via the USB-C port. On-device buttons are designed for simple operation, allowing for direct control over volume, track selection, and call management.
