Sena SRL-EXT Communication System

The Sena SRL-EXT brings premium communication, audio, and convenience to your ride with the perfect blend of Sena technology, Shoei integration, and SOUND BY Harman Kardon. Originally designed to fit seamlessly with Shoeis RF-1400, this low-profile system easily mounts to almost any helmet, giving you world-class connectivity without bulk or clutter. Whether youre commuting, touring, or riding with a group, the SRL-EXT keeps you connected, entertained, and in control.

The SRL-EXT combines both Mesh Intercom and Bluetooth intercom technologies for ultimate flexibility. Mesh mode allows riders to instantly connect across channels with a single tap, supporting near-limitless users within a 5-mile (8 km) range. For smaller, private groups, Group Mesh offers crystal-clear communication for up to 24 riders. Its a powerful, self-healing network that automatically reconnects riders as they move in and out of range no more fiddling with pairing or resetting connections.

Inside your helmet, youll experience SOUND BY Harman Kardon, delivering crisp highs, rich bass, and natural voice clarity through redesigned speakers and microphone. The system supports both wired boom and wired mic setups, allowing perfect audio quality for full-face, modular, or open-face helmets. With Bluetooth 5.0 support, you can stream music, follow GPS directions, or take phone calls without ever touching your device.

Why We Like It:
Its everything great about Senas latest Mesh systems, packed into a clean, compact design that looks like it belongs on your helmet. The Harman Kardon sound is impressive rich and clear even at highway speeds and the voice commands actually work, making it truly hands-free. It feels refined, integrated, and built for riders who care about both tech and aesthetics.

Why Itll Work for You:
A communication system like the SRL-EXT changes how you experience every ride. Whether youre coordinating with friends, listening to music, or following GPS directions, it keeps you informed and connected without taking your focus off the road. Mesh Intercom keeps your group linked without dropouts or complicated pairing, while voice control lets you handle calls, adjust volume, or ask for directions just by speaking.

The SRL-EXTs Harman Kardon audio makes long rides more enjoyable, transforming your helmet into a personal sound system. And when youre riding solo, its just as useful play music, check the weather, or get turn-by-turn navigation without pulling over or fumbling with your phone. Add in the sleek design, waterproof build, and compatibility across nearly any helmet, and its a communication system that fits the way you ride.
