Our headphones are specially designed for children aged 3 to 12 years old. The adjustable headband ensures a comfortable fit as your child grows. They can also be worn by teens with smaller head sizes.

Our headphones feature multiple volume limit levels (e.g., 74dB / 85dB / 94dB), easily adjustable to suit different environments. These settings are in line with WHO (World Health Organization) recommendations for safe listening levels for children.

Absolutely! All our models come with adjustable headbands and rotating ear arms, making them comfortable for kids of various ages. They also fold up easily for convenient storage and travel.

We use memory foam and soft protein leather for both the ear cushions and headband. These skin-friendly materials are breathable and provide long-lasting comfort—perfect for extended use by children.

Yes! Most of our models come with a high-quality built-in microphone, ideal for virtual learning, voice chats, and online classes.
(For wired models HK05/HK07 that do not have built-in mics, you can still speak into the device’s microphone—your voice will be picked up that way.)

Yes, the headphones are left-right specific. Please check the “L” (left) and “R” (right) markings on the earcups to ensure correct placement.
Wearing them the wrong way can affect the stereo experience—especially when watching videos or listening to audiobooks.

We recommend using a soft damp cloth for routine cleaning. Avoid alcohol-based or harsh cleaning agents.
Please note:
Do not submerge or rinse with water, as this may damage the electronics or materials.

After cleaning, let them air dry in a shaded, cool area—do not expose to sunlight or use heat to dry.
It’s best to clean them every 1–2 weeks, especially after long or summer-time use.

If you're storing the headphones for an extended period:

Wired models: Avoid tangling or tightly bending the cable—use a tie or pouch to keep it neat.

Bluetooth models: Turn them off completely and recharge every 2–3 months to prevent battery drain.
Store all headphones in a cool, dry place, away from moisture or direct sunlight, to extend their lifespan.

Yes, most Bluetooth headphones will automatically power off after about 10 minutes of inactivity to conserve battery.

To save power further:
Always turn them off manually after use (via power switch or long-press).
Avoid leaving them plugged in after full charging.
