EarFun Kids K2 are foldable over-ear Bluetooth headphones designed for children with safe volume limits, soft memory-foam comfort, and up to 40 hours of playtime.

These children’s headphones combine safety-focused engineering with everyday durability and wireless convenience. Built from kid-friendly materials that meet RoHS2.0, FCC, and CPC standards, the EarFun K2 pairs clear, balanced stereo from 40mm drivers with a volume cap that prevents listening above recommended levels. Lightweight and foldable, they’re made to travel to school, lessons, playdates, and family trips while delivering long battery life and a hands-free microphone for online classes and calls.

How do the K2 headphones protect my child’s hearing?

The EarFun K2 uses a hard volume limit to keep peak sound within safer thresholds and reduce the risk of accidental overexposure. Limits are set to commonly recommended decibel levels so parents don’t have to micromanage volume during use.

• Fixed volume limit to 85/94 dB to follow WHO-style guidance
• Built with CPC-certified materials suited for kids
• Soft memory-foam earpads that help passive noise isolation

Can these headphones last through a full day of school or travel?

Yes — EarFun K2 offers long runtime to cover schooldays, homework, or extended travel. When the battery runs low you can quickly recharge via USB-C for continued use in a few hours.

• Up to 40 hours of wireless playback on a single charge
• USB-C recharge delivers fast top-ups and continued wired use while charging
• Low-power Bluetooth connection helps extend battery life

Will the K2 fit kids comfortably and survive everyday wear?

The headphones prioritize comfort and durability with a flexible, ergonomic headband and cushioned ear cups for extended wear. Materials are chosen to be both soft on skin and wear-resistant so the set can bend, fold, and go into backpacks without breaking.

• Memory-foam headband and earpads for a cozy, secure fit
• Foldable, lightweight construction for easy storage and transport
• Robust build allows twisting and bending without damage

How good is the sound and will they work for calls or online lessons?
