The EarFun K2 Kids Bluetooth headphones are a foldable, volume-limited over-ear headset designed to keep children comfortable and listening safely with long battery life and clear stereo sound.

These violet EarFun K2 Kids headphones combine kid-friendly materials, a soft memory-foam fit, and smart audio limits so young listeners can enjoy music, online classes, and calls without excessive loudness. Built with Bluetooth 5.4, a built-in mic, and 40mm drivers, the K2 pairs wireless convenience with balanced sound and durable construction for everyday school and travel use.

How do the EarFun K2 Kids headphones protect little ears?

The K2 series enforces a ceiling on maximum volume to help reduce the risk of overexposure to loud sound. Volume is capped to match common safety recommendations, and the headphones use comfortable padding to minimize the need for higher volume in noisy environments.

• Preset maximum levels: 85 dB and optional 94 dB settings for different needs.
• Soft memory foam earpads create a good acoustic seal that improves perceived volume.
• Compliant materials meeting RoHS 2.0, FCC, and CPC checks for child use.

How long will the battery last during school or travel?

The K2 delivers multi-day listening on a single charge thanks to an efficient battery and low-consumption Bluetooth 5.4 radio. Typical real-world use covers many hours of lessons, playlists, or video calls before needing a recharge, with quick wired recharging available when required.

• Up to 40 hours of playback per full charge for extended use.
• USB-C recharging in approximately 2.5 hours for fast turnaround.
