Sena SRL-EXT Bluetooth Headset & Intercom - Shoei NXR2

The Sena SRL-EXT Bluetooth Communication System, designed specifically for the Shoei NXR2 helmet, features a main module and external battery with a curved design to match the exterior shape of the NXR2. Users have the flexibility to choose between a quick clamp or adhesive mount, with the main module installed on the left side and the external battery adhering to the right side of the helmet.

The SRL-EXT incorporates Sound by Harman Kardon, with expertly crafted speakers and an all-new microphone 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 can switch between the wired boom microphone and the wired microphone. The SRL-EXT offers both Mesh and traditional 4-way Bluetooth intercom, supporting Multi-Channel Open Mesh Intercom™ (Open Mesh) and Group Mesh Intercom™. Open Mesh allows a single push to connect to the Mesh Intercom™ network, with the ability to switch between nine channels, supporting a near-limitless number of users within a range of up to 5 miles / 8 km. Group Mesh supports a single private group for up to 24 participants, providing unprecedented intercom audio quality and robust connectivity. Sena's voice commands enable control of the SRL-Mesh system functions, connecting to Google Assistant or Apple's Siri. The optional Sena Motorcycles App allows users to visually configure device settings, manage channel settings for Open Mesh remotely, or set a private group for Group Mesh, available for both Android and iPhone via Google Play or Apple App store.
