Headphones — JBL JR310

Aimed at children, the JBL JR310 is a wired on-ear model engineered with JBL Safe Sound so that the volume never goes past 85 dB. It folds into a compact shape and adds a built-in microphone for calls and online lessons.

Key specs that matter

Both earcups use 32 mm dynamic drivers. Frequency response covers 20 Hz to 20 kHz, impedance is 32 ohms and sensitivity is 80 dB SPL at 1 kHz/1 mW. The closed design weighs 105 g and connects through a 3.5 mm jack.

Engineering and use context

The single-side flat cable resists tangling and carries an integrated mic and remote, with microphone sensitivity of -40 dBV at 1 kHz/Pa. A soft padded headband and custom ear cushions are designed for a comfortable fit on young listeners.

Alternatives

The JBL JR300 is a simpler kids model without the in-line microphone.
