Наушники — JBL JR300

JBL built the JR300 wired on-ear headphone at a size for children around JBL Safe Sound, which keeps the volume below 85 dB, and gave it a compact, foldable design that makes it easy to carry in a school bag.

Key specs that matter

Frequency response is 20 Hz to 20 kHz, sensitivity is 85 dB SPL at 1 kHz/1 mW and impedance is 32 ohms. The closed-back headphone weighs 108 g.

Engineering and use context

A single-side flat cable reduces tangling, while a custom soft padded headband and ear cushions are shaped for smaller heads. Stickers are included so kids can personalise the earcups.

Alternatives

The JBL JR310 is a related kids model whose cable also carries a mic and remote.
