Instruction manual


Sena's adaptive mesh networking technology makes it effortless to connect the group intercom. And when a rider goes out of range, the Sena ensures seamless communication with the rest of the group. At the same time, the Sena 50S automatically reconnects all drivers to the group once they are back in range. With this dynamic group structure, complicated pairing attempts are a thing of the past.

Thanks to Sena's pioneering adaptive mesh networking technology, which works in combination with Bluetooth, the 50S has more connections than ever before. With an innovative dual antenna and two separate processors, one for Bluetooth and one for Adaptive Mesh Networking, the 50S can connect to each processor at the same time thanks to multi-operation. This means you can connect up to 3 other communication devices to your Sena 50S headset via Bluetooth 5.0 and then integrate them into an existing mesh networking group at the same time.

Communicate reliably and clearly in HD audio quality with up to 24 other riders at a maximum range of 2 km. The 50S also allows for targeted group management, so you can divide users into groups and differentiate between them. In addition to these private groups, you can search for motorcyclists within a 2km radius who are also using a Sena 50S at the touch of a button. You will be automatically connected to them.

Sena 50S audio multitasking technology allows you to have conversations via Adaptive Mesh networking while streaming music from your smartphone via Bluetooth, taking or making phone calls, or playing back detailed GPS navigation instructions. Users no longer have to fret over interruptive audio features of previous Bluetooth communication devices. Now, instead of interrupting each other, the audio functions overlap to create an enjoyable listening experience. Add seamless audio sources to your journeys.

Use the Sena smartphone app to configure device settings (e.g. enter a group of biker friends for hands-free calling) and take a look at the quick start guide. Simply pair your phone with your 50S headset and run the Sena smartphone app. This way you can adjust the settings directly from your smartphone.

The 50S's new fast-charging feature provides around 3 hours of use after just 20 minutes of charging. On the road, the 50S can be controlled entirely by voice commands. The intuitive technology ensures safe, controlled driving by seamlessly switching between music, phone and intercom functions.

The 50S' universal mounting option with clamp and/or adhesive mount and interchangeable cable and gooseneck microphone allows it to be used with almost any helmet, whether jet, flip-up or full-face. The Sena 50S is compatible with Sena's optimal Handlebar Remote control and all 20S clamp accessories.
