Using mesh networking technology, one click of a button is all it takes to instantly connect to an almost unlimited number of SENA 33i users within a one kilometer radius. The 33I, with its more stable connection, intelligently searches for lost intercom connections and automatically reconnects once in range, all without affecting the rest of the group. SENA 33I improvements: • New chipset that upgrades Bluetooth from 4.1 to 5.0 • Faster startup time. • Improved voice command functions. • New charging cable (USB-C) for faster charging • Superior quality loudspeakers. • Removing auxiliary port or FM radio.
