The 3S Plus Boom represents Sena's most elegant and minimal solution, designed to integrate seamlessly into Jet and Open-Face helmets. Unlike any other model, the 2-button control is cleverly incorporated directly into the boom microphone, eliminating the need to attach any external elements to the helmet shell.
Thanks to Bluetooth® 5.1 technology, the 3S Plus Boom delivers a surprising audio experience: it allows you to manage music, calls, GPS directions, and 2-Way HD Intercom conversations with a passenger or riding companion up to 400 meters away.
To ensure maximum clarity, Advanced Noise Control™ filters out road and wind noise, ensuring your voice is always clean and clear. The unit offers 20 hours of talk time on a single charge and features incredibly easy installation due to the unified speaker structure.
