Learn how to set up and use a LED Cube Speaker for kids. Step-by-step instructions for safe, fun Bluetooth speaker use with light-up effects.

Quick answer

To use a LED Cube Speaker for kids, plug it into a USB power source, pair it via Bluetooth with a phone or tablet, then play music. The speaker lights up to the rhythm automatically.

Why this speaker works well for children

The LED Cube Speaker is small (7 cm) and simple to use, making it a great first gadget for kids aged 12 and up. It connects wirelessly via Bluetooth, so there are no tangled cables. The 3W output is enough for a bedroom or playroom without being too loud.

Because it is USB powered, you can plug it into a computer, power bank, or wall adapter. This also means the speaker stays on as long as it has power, so you do not need to worry about batteries dying mid-song.

What to watch out for

The speaker is not waterproof, so keep it away from drinks or sinks. Also, the Bluetooth range is about 10 meters (33 feet), so the paired device should stay in the same room for a stable connection.

Since the speaker is powered by USB, you need a separate USB adapter if you want to plug it into a wall outlet. Many kids' rooms already have a USB port on a computer or game console, but check before you buy.

How to set up and use your LED Cube Speaker

Plug in the speaker: Connect the USB cable to the speaker and plug the other end into a USB power source (computer, power bank, or wall adapter). The speaker will light up to show it has power. Make sure the USB source is turned on; some computers have USB ports that only work when the computer is awake.
Enable Bluetooth on your device: On your phone, tablet, or computer, go to Settings > Bluetooth and turn it on. Make sure the device is discoverable. If the device does not find the speaker, check that the speaker is not already connected to another device. Turn off Bluetooth on any nearby devices that were previously paired.
Pair the speaker: In the Bluetooth menu, look for 'LED Cube Speaker' or a similar name in the list of available devices. Tap it to pair. You may hear a confirmation sound or see a steady light. If the speaker does not appear, try turning the speaker off and on again, or move the device closer to the speaker (within 1 meter).
Play music and enjoy the lights: Open your music app and play a song. The speaker will play the audio, and the LED lights will flash and change colour in time with the beat. Adjust the volume on your device or directly on the speaker if it has a button. The lights are automatic and cannot be turned off separately. If you want a quieter light show, lower the volume or choose a song with a slower tempo.
Turn off and store safely: When done, disconnect Bluetooth from your device's settings, then unplug the USB cable. Store the speaker in a dry place away from liquids. Unplugging the USB cable turns off the speaker completely. Leaving it plugged in with no music playing keeps the lights on, which may be distracting at night.
