Kids ANC Headphones with 70-Hour Battery

Tronsmart KH03 headphones combine active noise cancellation with a 70-hour battery so children can listen through long journeys or study sessions. A built-in 40 mm dynamic driver covers a 20 Hz to 20 KHz range at 32 Ω impedance. Bluetooth 5.3 handles wireless pairing while a 3.5 mm cable adds wired flexibility. The pink finish includes selectable LED light modes for visual appeal.

Check Device Compatibility and Fit

Verify that the source device supports Bluetooth 5.3 or has a standard 3.5 mm audio jack for the included cable. The over-ear design weighs 0.54 pounds and uses protein earpads sized for smaller heads. Three volume limits — 74 dB, 85 dB and 93 dB — let parents match the cap to the child's age and environment. Ensure the 5 V / 500 mA charging input matches your available power adapters.

Upgrade from Basic Kids Headsets

These replace non-ANC models that lack noise isolation for classrooms, flights or busy homes. The 70-hour runtime removes the daily charging habit required by shorter-life sets. Integrated HD microphone improves clarity for online lessons compared with boomless or omitted mics. The jump is worth it when background noise disrupts focus or when battery anxiety limits wireless freedom.

Questions about this item

Does the box include the 3.5 mm audio cable for wired use or must it be purchased separately?

The 3.5 mm audio cable is supplied in the box so the headphones work in both wireless and wired modes without any extra purchase.

Which of the three kid-safe volume limits — 74 dB, 85 dB or 93 dB — should I select for my child?

Choose 74 dB for the youngest listeners, 85 dB for everyday use, and 93 dB only when a slightly higher level is needed; all three are built in and selectable on the headphones.

What does the 70-hour playtime mean when Active Noise Cancellation and the LED lights are both turned on?

The 70-hour figure is the quoted operating time; enabling ANC and the two lighting modes will reduce actual runtime, but the battery still provides multi-day listening on a single charge.
