Multi-channel Open Mesh supports 9 channels, letting you switch between different groups on different frequencies. Sena’s Mesh platform offers flexibility by allowing riders to come in and out of range while keeping the rest of the group connected.

SEAMLESS DESIGN FOR EASY HANDS-FREE COMMUNICATION
Audio is delivered through integrated speakers located above the rider’s ears, which allows for awareness of surrounding sounds such as traffic, unlike in-ear buds. The redesigned speakers have been optimized in order to keep the helmet as slim as possible for less wind resistance. Located in the front of the helmet is a built-in microphone that houses Sena's patented Advanced Noise Control™ technology, picking up and transmitting your voice clearly.
