 Feature:
1. Technical Principle
· Bone conduction technology: Transmits sound signals directly to the cheekbone or skull through vibrations, bypassing the eardrum, reducing direct stimulation to the ear canal and protecting hearing.
· Open ear canal design: The ear is not blocked when worn, allowing children to hear ambient sounds (such as traffic and parents calling), improving outdoor safety.
2. Safety and Health Design
· Low volume limit: Prevents hearing damage from prolonged use.
· No eardrum pressure: Avoids the pressure on the ear canal caused by traditional in-ear headphones, reducing the risk of otitis media and discomfort.
· Eco-friendly materials: Made of non-toxic, hypoallergenic ABS + PS + Silicone to prevent skin allergies.
3. Comfort and Durability
· Lightweight design: Typically weighing less than 30 grams, it avoids pressure on the head or neck.
· Adjustable structure: The elastic adjustment design accommodates different head circumferences (children aged 3-12 years).
· Sweat and water resistant: With a waterproof rating of IPX5 or above, it is suitable for exercise and daily use. · Drop and Wear Resistance: The outer shell is made of ABS material, which is drop-resistant and scratch-resistant.
4. Fun
· Colorful Appearance: Bright colors attract children's interest.
5. Usage Scenarios
· Learning and Entertainment: Online classes, storytime, and music playback.
· Outdoor Sports: Staying aware of the environment while cycling or running.
· Special Needs: Suitable for children with sensitive ear canals or those wearing hearing aids.
6. Purchasing Recommendations
· Age-Based Selection: For younger children (3-6 years old), choose the softer headband style; for older children (7+ years old), choose the ear-hook style.
· Parent Choice: Children's bone conduction earphones balance entertainment and safety through technological innovation, offering a healthy alternative to traditional earphones and are particularly suitable for parents who value hearing protection.
