## Long description

Livall BH51M NSO Black is a half helmet with a hard shell polycarbonate construction designed for urban and leisure cycling. The compact shape covers the top and sides of the head while keeping ventilation channels and a lightweight fit. Integrated smart features include Sound by JBL open-ear speakers, Bluetooth connectivity, a windproof microphone, and a bar-mounted remote controller for hands-on-bar operation. Built-in sensors provide fall detection with SOS alert, 360° LED lighting, turn signals and brake warning lights, and the helmet meets multiple safety standards for bikes, scooters and skateboards.
Advantages
The polycarbonate hard shell delivers impact protection while the compact half-helmet design preserves ventilation and low weight for everyday use. Open-ear JBL speakers and improved sensitivity offer clearer music and call audio without completely blocking ambient sound, preserving situational awareness. The combination of fall detection with automatic SOS messaging and 53 integrated LEDs for 360° visibility provides both passive and active safety measures. Additional features such as the FIDLOCK magnetic buckle, IPX4 water resistance, adjustable dial-fit wheel and up to 12 hours of battery life support comfortable, reliable daily use.

Usage recommendations
