Communication by SENA, protection by Shoei, and sound by Harman Kardon. The SRL-EXT was custom designed for one of Shoei's most beloved helmets, the RF-1400. The compact SRL-EXT offers both Mesh and Bluetooth intercom plus smartphone connectivity for music, GPS, phone calls, and more. SRL-EXT users will experience premium sound by Harman Kardon audio inside of their Shoei RF-1400.

Designed for the Shoei RF-1400:

The SRL-EXT was tailored specifically for the Shoei RF-1400 helmet. The shape of the SRL-EXT main module and external battery are curved to match the exterior curves of the RF-1400. The SRL-EXT allows users the option of a quick clamp or adhesive mount. 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.

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 RF-1400 helmet with the SRL-EXT.

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.

Hands Free Convenience with Sena's Voice Commands:

Convenient voice commands give you control of the SRL-EXT's system functions, such as answering the phone or starting up a Group Mesh session. The SRL-EXT supports voice commands across eight languages

Looking for a bite to eat? "Hey Google, directions to the nearest sandwich shop."
