DESIGNED FOR SHOEI HELMETS

The SRL-EXT was tailored specifically for the SHOEI NXR2 helmet.  The shape of the SRL-EXT main module and external battery are curved to match the exterior curves of the NXR2.  The SRL-EXT main module is installed on the left side of the helmet, while the external battery adheres to the right side of the helmet.

HANDS FREE CONVENIENCE

WITH SENA’S VOICE COMMANDS

Convenient voice commands allow you to control the SRL-EXT’s system functions, such as answering the phone or starting up a Group Mesh session.  The SRL-EXT supports voice commands in eight languages: English, French, German, Spanish, Italian, Chinese, Japanese, and Russian!

Looking for a bite to eat? “Hey Google, directions to the nearest sandwich shop.” The SRL-EXT easily connects to Google Assistant and Apple’s Siri with a simple voice command allowing you to tap into the power of your smartphone’s features, including GPS navigation, music playback, voice dialing, plus a variety of other digital assistant features.

MESH & BLUETOOTH® INTERCOM

The SRL-EXT offers both Mesh Intercom™ and traditional 4-way Bluetooth® intercom, allowing for compatibility with any Sena or Sena-powered device.  Sena’s industry-leading Mesh Intercom™ communication platform has two modes: Multi-Channel Open Mesh Intercom™ (Open Mesh) and Group Mesh Intercom™.

Open Mesh offers a single push of a button to click-to-connect to the Mesh Intercom™ network and features the industry’s first Mesh Intercom™ channel system.  Like standard handheld or CB radios, Open Mesh lets users switch between nine channels.  It also supports a near-limitless number of users within a range of up to 5 miles / 8 km (min. 6 riders @ 1 mi / 1.6 km intervals).

Group Mesh supports a single, private group for up to 24 participants and the same range as Open Mesh for a more intimate group conversation.  Only invited users can join the Group Mesh chat. Open Mesh and Group Mesh provide unprecedented intercom audio quality and robust connectivity.

SOUND BY Harman Kardon

The SRL-EXT’s speakers and microphone were created with the audio experts at Harman Kardon to provide world-class sound inside your SHOEI helmet.  Expertly crafted speakers and an all-new microphone allow the SRL-EXT to deliver an unmatched audio experience.  The speakers send clear audio to riders’ ears while the microphone, with a redesigned sensor, provides robust performance for voice communication.  Users will be able to switch between the wired boom microphone and the wired microphone. Experience SOUND BY Harman Kardon inside of your SHOEI helmet with the SRL-EXT.
