# SENA SMART HJC 50B UNIT BLACK

-   Bluetooth 5.0 with Mesh Intercom and 4-Way Bluetooth Intercom: Based on the SENA 50S/50R platform, the SMART HJC 50B delivers both Mesh Intercom and traditional 4-way Bluetooth intercom — up to 2 km (1.2 miles) Bluetooth range and 8 km (5 miles) Mesh range with 6+ riders.
-   Audio Multitasking and Sound Equalizer: Listen to music, GPS navigation, and intercom simultaneously with Audio Multitasking; the built-in equalizer lets you tune the sound profile to your preference.
-   Advanced Noise Control: Sena's Advanced Noise Control technology cuts through wind and road noise so your calls and intercom conversations stay clear at any speed.
-   HD Speakers for Enriched Audio: Second-generation HD speakers are tuned specifically for mid-to-low pitched frequencies, delivering noticeably richer, fuller sound compared to standard motorcycle communicators.
-   Dual Control Units (One Each Side): The 50B comes with two control units — one for each side of the helmet — allowing operation from either hand for maximum riding convenience.
-   Voice Command Support: Control calls, intercom, music, and navigation with voice commands, and connect to Google Assistant or Apple Siri for hands-free smartphone integration.
-   Compatible HJC Helmets: Designed for HJC RPHA 71, RPHA 91, RPHA 31, i71, i91, F71, and F31 helmets. Co-developed by Sena and HJC for seamless integration.

If you ride in a group and want the best-integrated communication system your HJC helmet can carry, the SMART HJC 50B is the answer. Co-developed by Sena and HJC, the 50B is built on the same Bluetooth 5.0 platform as the Sena 50S/50R — meaning you get both Mesh Intercom for dynamic group communication and traditional 4-way Bluetooth intercom in a single fully-integrated unit. The Mesh Intercom range reaches up to 8 km with 6 or more riders, while 4-way Bluetooth intercom stretches to 2 km. Dual control units — one on each side of the helmet — let you manage everything from either hand, and HD speakers deliver noticeably richer audio than standard communicators. Audio Multitasking keeps music, navigation, and intercom all available simultaneously, and voice command support through Google Assistant and Siri keeps your hands on the bars. At The Helmet Shop, the 50B is our top recommendation for HJC riders who want the ultimate integrated communication experience. Backed by Sena's warranty.
