The Mesh Intercom equipped S1 combines safety and technology into a sleek and aerodynamic package built for road cyclists. Sena's Mesh Intercom allows riders to communicate hands-free with other Mesh users (R1 EVO, R2 EVO, M1 EVO) within .8 miles (1200 meters). 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. Bluetooth 5.2 technology allows you to connect to your smartphone, enabling you to make phone calls, listen to your music, hear GPS navigation, and even connect to fitness apps. Age Grade: Adult
