Highlights

Premium JBL Open-Ear Audio

Equipped with upgraded JBL open-ear speakers (57% larger speaker size, +5dB sensitivity, -180Hz resonance frequency), the BH51M NSO produces full rich bass and crisp mid-high tones. You enjoy music & calls while keeping full awareness of surrounding road sounds for safe riding.

All-Round Intelligent LED Safety Lighting

53 built-in front & rear LED lights support auto-sensing illumination, brake warning and turn signal reminders, effectively alerting surrounding vehicles from all directions to boost cycling safety day and night.

Smart Auto Power & Long-Lasting Battery

Auto powers on within 4s when worn and auto shuts down after removal; LED brightness auto-adjusts to save power. Up to 12-hour runtime per charge, the low-temp battery still keeps ~80% capacity even at -20°C for long outdoor use.

FIDLOCK Magnetic Quick-Release Buckle

Advanced FIDLOCK magnetic buckle enables one-snap fast locking, replacing cumbersome traditional buckles for effortless helmet wearing and reliable riding safety.

Handlebar Remote Control & Anti-Lost Alert

Handlebar-mounted remote realizes hands-free control for turn signals, one-click call answer, voice command and PTT walkie-talkie. An anti-loss alarm triggers on both helmet and phone once separated over 20m/65ft to avoid equipment loss.
