Sena Smart HJC 21B

Specifically designed to fit and integrate with HJC F71, i71, i91, RPHA 31, 71 and 91 model helmets.

SMART HJC 21B is built on Sena's S10 series platform which provides Bluetooth 5.1 with over 13 hours talk time in a 4-way intercom system.
Unlike other intercom systems, which have to be placed on the outside of a helmet, the Sena / HJC 21B control unit sits flush inside the comm system cavity while the battery is hidden in the lower back of the helmet. Easy accessible and easy to re-charge.
