Sena 3S Plus Bluetooth Intercom - Single

The Sena 3S Plus Universal (3SPLUS-WB-10) is an ultra-compact, minimalist motorcycle communication system engineered for riders who want reliable connectivity without cluttering the exterior of their helmet. Stripping away massive plastic housings and complex control arrays, this stealthy headset is a masterclass in clean installation, making it the perfect match for urban commuters, scooter riders, cruiser enthusiasts, and touring duos who favor a low-profile aesthetic.  

Utilizing an advanced Bluetooth 5.1 architecture, the 3S Plus Universal houses its entire brain right inside the ultra-slim ear speaker housings. A tiny, external two-button control pad mounts flush to the shell of your helmet, offering foolproof adjustments even with thick gloves. Despite its micro size, this kit packs punchy high-definition sound and seamless smartphone pairing, delivering everything you need to stay connected on the move.  

Key Features

Micro-Sized Design & Bluetooth 5.1

Ultra-Low Profile Footprint: The absolute sleekest external controls available on the market. The tiny 2-button module attaches cleanly to the helmet shell, preserving your helmet’s aerodynamics and styling.  

Integrated Speaker Electronics: Cleverly houses the main processor and components directly within the speaker assembly, minimizing internal wiring and eliminating the need for bulky side-clamps.

Stable Bluetooth 5.1 Protocol: Built on high-efficiency Bluetooth technology to guarantee instantaneous device pairing, stable data streaming, and optimized battery consumption.

HD Intercom & Advanced Noise Control™

2-Way Passenger or Rider Comms: Supports full-duplex, rider-to-passenger or rider-to-rider communication for up to two participants to talk simultaneously.  

400m Working Range: Delivers a reliable, clear intercom connection across a 400-metre (0.25-mile) range in open terrain, keeping you connected through city traffic and country bypasses.  

HD Intercom Audio: Delivers superior sound clarity with deep bass and sharp vocals, ensuring conversations or music tracks sound crisp at speed.  

Advanced Noise Control™: Sena’s proprietary ambient noise-suppression algorithm actively filters out rushing highway wind noise, tire roar, and deep engine drone so your voice stays perfectly audible.  

Smart Syncing & Universal Fitment

Universal Microphones Included: The WB-10 kit includes both a flexible wired boom microphone (ideal for open-face and flip-up modular helmets) and a thin wired button microphone (perfect for full-face lids).  

Wireless Device Integration: Syncs seamlessly with your smartphone to route turn-by-turn GPS voice prompts, stream wireless music playlists, or take hands-free phone calls.  

Sena Motorcycles App Compatible: Easily customize device settings, configure pre-set speed dials, or access the digital quick-start guide by pairing the headset with the official Sena app on iOS or Android.  

Smart Intercom Pairing (SIP): Allows you to connect with a riding buddy instantly by simply scanning a QR code generated within the Sena app on their smartphone.
