The BTH20 is iClever's hybrid noise-cancelling headphone for children aged 3 and up, made for flights, road trips and noisy rooms. Outer and inner microphones work with the ear-cup seal for up to 40 dB of noise reduction, with a High mode for engine noise and a gentler Low mode for kids who feel ear pressure. iClever publishes an 80 dBA volume limit. Battery life is 60 hours with ANC off or 35 hours with it on, and a 10-minute charge adds about 5 hours. A 3.5 mm cable is included, though ANC does not work in wired mode.
Key features
Hybrid ANC with two strengths
Outer and inner microphones plus passive isolation give up to 40 dB of noise reduction. The headphones start in High mode; the ANC button then switches to Off and to a gentler Low mode that iClever suggests for kids sensitive to ear pressure.
80 dBA volume limit
iClever publishes an 80 dBA limit and uses its Sound Refiner tuning to reduce output in the 2–4 kHz range. Parents should still keep an eye on listening time.
Long battery, quick top-up
The 500mAh battery runs 60 hours with ANC off or 35 hours with it on, and a full charge takes about 2 hours. Ten minutes on USB-C adds around 5 hours, and the 3.5 mm cable works when the battery is flat.
Fit and build for kids
Ear cups rotate 90° and the headband has 10 adjustment steps, sized by iClever for ages 3 and up. Large buttons, a soft skin-like finish, BPA- and PVC-free materials and a built-in mic for wireless calls complete the package.

FAQ
Does noise cancelling work with the audio cable?
No. The iClever manual states noise cancelling is not supported over a wired connection, so ANC works over Bluetooth only.
How do I switch between the noise cancelling modes?
The headphones start in High mode. Press the ANC button once for Off, again for Low, and a third time to return to High.
What is the volume limit?
iClever publishes an 80 dBA volume limit for the BTH20, with no adjustable levels listed. It is still wise to manage listening time.
