Sena 3S Plus Universal: integrated Bluetooth audio for compatible MM Independent helmets
The Sena 3S Plus Universal delivers clear audio through Bluetooth 4.1 for music, phone calls, GPS instructions and intercom communication at distances of up to 400 metres. Voice prompts are available in 11 languages, keeping operation simple and discreet.
Available exclusively when purchasing a compatible MM Independent helmet, because the helmet is manufactured with the intercom integrated. It is not sold separately. NOT COMPATIBLE with A‑VENTURA helmets.
Design and installation
The two-button external controls integrate neatly with compatible helmet types. Installation is carried out as part of the helmet build, preserving a clean appearance and immediate access to the controls. The 3S Plus Universal includes two microphone options: a standard microphone and a boom microphone, depending on the helmet configuration.

Why choose MM Independent
MM Independent selects accessories that are compatible with and tested on its helmets, ensuring proper integration, reliable audio quality and an appearance consistent with the design of the helmet.
CHROMETECH® is the only colour finish with a reflective effect in any lighting conditions. Under artificial light, such as car headlights, Chrometech® reflects the light source, making it far more visible than a conventional colour finish.
This reflective effect helps make the rider clearly visible on the road, even from a distance, especially at night, while giving the helmet exceptional depth and a distinctive appearance.
