Sena EXPAND Mesh Intercom Headset

Lightweight, licence-free, and ready to go the moment you put it on. The Sena EXPAND Mesh is a compact over-ear communications headset built on Mesh Intercom 3.0 — ideal for outdoor work teams, site supervisors, and anyone who needs reliable hands-free group comms without the bulk of a radio or the faff of pairing.

Used by teams like WJ Roadmarkings, where keeping a crew connected across a live site is a daily operational requirement, the EXPAND Mesh delivers clear, instant communication at the touch of a button. No base station. No licence. No configuration.

Open Mesh supports 6 channels with virtually unlimited participants — switch between groups on different frequencies effortlessly. Group Mesh allows up to 24 participants in a private session. Range up to 400 m in open terrain, extendable to 1.6 km with 6 or more users. Compatible with any Sena Mesh Intercom™ device, so it integrates into an existing Sena setup without issue.

The low-profile over-ear design maintains ambient awareness — important on live roads and active sites. The low neckband means hard hats, climbing helmets, caps and glasses all work alongside it. At just 100 g, it won’t slow anyone down.
