The 3S Plus Boom headset features Bluetooth 4.1 technology for music, phone calls, GPS, and intercom up to 0.25 miles away. Its two-button control is cleverly integrated into the boom microphone, eliminating the need for external elements on the helmet shell, making it ideal for Jet or open-face helmets. The system includes a two-way HD intercom with Advanced Noise Controls, offers up to eight hours of talk time, and connects to the Sena Utility App for settings customization.
