JBUNION SBT-399
Three selectable volume limits (75/85/94dB) safeguard hearing, while 40mm drivers, Bluetooth 5.4, and a 30-hour battery deliver steady wireless audio. The foldable, 200g design uses BPA-free materials, includes a 3.5mm aux cord for wired fallback, and adds a playful dinosaur motif that kids enjoy. These are best for parents equipping children aged 7+ for school commutes, travel, or tablet time where hearing protection is a priority.
