The BTH12 suits kids who want light-up headphones that last through a week of school runs and tablet time. iClever lists two volume limits, 74 dBA and 85 dBA, switched by pressing both volume keys together. An 800mAh battery gives up to 85 hours with the lights off or 53 hours with the four RGB light modes on. It folds, has a built-in mic for calls and online lessons, connects over Bluetooth 5.2 and comes with a 3.5 mm cable for wired use. This listing is the blue version.
Key features
Two volume limits
iClever publishes two limits: 74 dBA and 85 dBA, with 85 dBA as the default. Press the + and − keys together to switch, and the headphones remember the last setting.
Four RGB light modes
A light strip on each ear cup offers revolving, breathing, quick flash and slow flash effects. A short press of the light button changes the mode.
85 hours with the lights off
The 800mAh battery lasts up to 85 hours with the lights off or 53 hours with them on, and a full USB-C charge takes about 2.5 hours. iClever says a 10-minute charge gives around 7 hours of music.
Mic, wired mode and folding design
A built-in microphone handles calls and online classes, and the included 3.5 mm cable lets kids keep listening when the battery is flat. The headband adjusts and the headphones fold for the school bag.
