Note: Depending on the size and shape of your helmet, you may
need to change the thickness of the rubber pad between the clamp
plates using the two extra rubber pads in the box. To increase the
overall thickness, attach the thinner one to the original rubber pad
or replace the original rubber pad with the thicker one.
2. Place the helmet speakers along with the hook and loop fasteners,
centered to your ear, in the ear pockets of the helmet. If the helmet

Charging the Headset
DC Power Charging &
Firmware Upgrade Port
You can charge the headset by
connecting the WiFi Adapter
or a USB Power & Data Cable
(USB-C).
A USB Power & Data Cable
(USB-C) is not included in the
package.
The headset will be fully charged in about 2.5 hours. (The charging time
may vary depending on the charging method.)

• The headset includes a Fast Charging feature which allows it to
charge quickly over a short period of time. For example, a user
can get up to 2.0 hours of Mesh communication or 2.0 hours of
Bluetooth intercom after charging the headset for 20 minutes.
• Any 3rd party USB charger can be used with Sena products if the
charger is approved by either the FCC, CE, IC, or other locally
approved agencies.
• Use of a non-approved charger may cause fire, explosion,
leakage, and other hazards which may also reduce the life time or
performance of the battery.
• The 50S is compatible with 5 V input USB-charged devices only.

4. PAIRING THE HEADSET WITH OTHER
BLUETOOTH DEVICES
When using the headset with other Bluetooth devices for the first time,
they will need to be “paired.” This enables them to recognize and
communicate with one another whenever they are within range.
The headset can pair with multiple Bluetooth devices such as a mobile
phone, GPS, MP3 player or Sena SR10 Two-Way Radio Adapter via
Mobile Phone Pairing, Second Mobile Phone Pairing and GPS
Pairing. The headset can also be paired with up to three other Sena
headsets.

sharing music while Bluetooth intercom and Mesh Intercom are running
at the same time, then music shared during Bluetooth intercom will take

7. MESH INTERCOM
7.1 What is Mesh Intercom?
Mesh Intercom™ is a dynamic communication system created by Sena
that provides instant and effortless bike-to-bike communication without
a pre-grouping process. Mesh Intercom allows riders to connect and
communicate with nearby users without the need to pair each headset
together.
The working distance between each 50S in Mesh Intercom can be up
to 2 km (1.2 miles) in open terrain. In open terrain, the Mesh can be
extended up to 8 km (5 miles) between a minimum of six users. Within
the same channel in Open Mesh™ or the same private group in Group
Mesh™, six users can talk at the same time and enjoy the optimal
quality for their conversation.

7.1. 2 Group Mesh
Group Mesh is a closed group intercom function that allows users to
join, leave, or rejoin a group intercom conversation without pairing each
headset. Users can freely communicate with each other in the same
private group in Group Mesh.
For closed intercom conversations using Mesh Intercom, a Group
Mesh needs to be created by the users. When users create a private
group in Group Mesh by Mesh Grouping, the headset automatically
switches from Open Mesh to Group Mesh. Up to 24 users can all be
connected in each private group.
