  • 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.

READY FOR ADVENTURE
WITH SENA APP

Customize a variety of settings on your Sena device with the Sena Motorcycles App. Configure channel settings for Open Mesh or set a private group for Group Mesh. Explore all-new soundscapes with the EQ presets and give the audio a boost. Connect your Sena headset to your phone in the Bluetooth settings menu and get the most out of your adventures.
