EarFun K4
The 90-hour battery life and triple-volume limit (74/85/94dBA) make these over-ears safe for kids, while 40mm drivers and Bluetooth 5.4 provide clear stereo sound. At just 213g and foldable, with five colorful LED light modes and a 10-minute fast charge for 8 hours, it combines portability with fun. Best for school-age children needing durable, hearing-safe headphones for tablets and travel, backed by Rohs2.0 and CPC safety certifications.
