Safe Listening for Children

The Acesori HK03 over-ear headphones are built for children who need wired audio at school, at home or while travelling. A built-in limiter offers two maximum levels at 85 and 94 dB to protect developing hearing. The 3.5 mm plug works with tablets, laptops and most portable devices without extra adapters.

Simple Setup and Daily Care

Plug the 3.5 mm jack into any compatible port and the headphones are ready; no drivers or pairing are required. The foldable frame reduces bulk in a backpack, while the tangle-free cable resists knots during storage. Volume control sits on the earcup for quick adjustment by small hands.

Suited for Young Listeners, Not Wireless Users

These headphones suit parents who want a lightweight, volume-limited set for everyday learning and entertainment. Buyers who need Bluetooth connectivity, active noise cancellation or a detachable boom microphone should look at other models.

Questions about this item

How can I confirm the 85 dB or 94 dB volume limiter is active after I plug the headphones in?

The HK03 has a push-button volume control that toggles between the two limiter settings; an audible click and a change in maximum loudness let you verify the active mode.

What comes in the box and what extra items are needed to use the headphones?

The package includes the Acesori HK03 headphones and a user manual; the 3.5 mm plug works directly with any device that has a matching jack, so no separate cable or adapter is required.

The specs list a single green HK03 model — how do I choose between the 85 dB and 94 dB settings?

Both limits are built into the same headset; press the volume-control button to switch between the lower 85 dB setting for younger children and the higher 94 dB setting for older kids or noisier environments.
