The 40mm drivers and Bluetooth 5.4 deliver clear audio, while the 90-hour battery and triple-level volume limiting (74/85/94dBA) ensure safe all-day listening in a 210g BPA-free build. Five LED light modes add fun, and a 10-minute charge provides 8 hours of playtime. Ideal for parents equipping school-age kids with durable, hearing-protective headphones for tablets, online learning, and travel.
