Tronsmart KH03 Kids Bluetooth 5.3 ANC Headphones

These over-ear headphones are built for children who need wireless audio with active noise cancellation and a strict volume limit. They suit home learning, travel and everyday listening on tablets, smartphones or PCs. The foldable frame and protein earpads keep long sessions comfortable for younger users.

Wireless ANC with 70h battery and 3.5mm backup

Bluetooth 5.3 handles the wireless link while the built-in lithium cell delivers up to 70 hours of playtime between charges. A 3.5mm cable is included for wired use when the battery runs low or when a device lacks Bluetooth. Active noise cancellation reduces background sound so the listener can focus on lessons or media.

Replaces basic kids headphones that lack ANC

The jump is worth it when a child regularly studies in noisy rooms, flies often or needs hearing protection capped at 74dB, 85dB or 93dB. It is not for buyers who want more storage, builders who need a second card, or anyone requiring a detachable boom microphone for competitive chat.

Questions about this item

How long does the 70-hour battery last with ANC on all day?

The built-in lithium battery delivers 70 hours of playtime; ANC use will reduce that figure, but no separate ANC-on rating is published.

What is the noise level and heat output when the headphones run continuously?

Passive over-ear design produces no fan noise or measurable heat; only the 40 mm drivers and ANC circuitry operate, both staying cool during extended wear.

Which devices can I connect to the 3.5 mm jack for wired listening?

Any source with a standard 3.5 mm audio output — PC, tablet, smartphone, or in-flight entertainment system — works in wired mode with volume limited to 85 dB.
