MESH and SOUND BY Harman Kardon. DESIGNED FOR SHOEI HELMETS

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 AND 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.

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.
