How many riders can join a Mesh conversation?

Mesh 2.0 supports large open groups, and Sena's mesh networks let riders join without pairing one by one. The practical group size depends on the mode and conditions.

Does it work with any helmet?

It mounts to most full-face, modular and open-face helmets using the included clamp or adhesive mount. The slim Harman Kardon speakers fit more helmets than older, thicker speakers.

Can I use it with Siri or Google Assistant?

Yes. It supports direct digital assistance and voice commands for Siri and Google Assistant when paired to a compatible phone.

How long does the battery last and how fast does it charge?

Sena rates it at 9 hours of Mesh talk or 14 hours of Bluetooth talk. A 20-minute charge gives about 3.5 hours of Mesh or 6 hours of Bluetooth use.

What is the difference between the single and dual pack?

The single pack includes one headset, and the dual pack includes two, intended for rider and passenger or two bikes. Both use the same 50S unit and HD speakers.

Is it worth it over the older 30K?

The 50S adds Mesh 2.0, Bluetooth 5.0 and the Harman Kardon speakers. Riders who use group mesh and care about audio get more from the 50S; solo Bluetooth users may not need the upgrade.
