Sena Yachting Crew Communications Headsets (Bosun Quad Pack)

Keep your entire crew on the same wavelength. The Sena NAUTITALK Bosun is a purpose-built maritime communications headset with Mesh Intercom 3.0 — designed for the unique demands of sailing, where reliable crew communication can be the difference between a clean manoeuvre and a costly mistake.

This quad pack contains four Bosun headsets, ideal for racing teams, charter crews, or any boat where four people need to stay connected. IPX7 submersible waterproof and built to float if dropped overboard — two things the Eartec UL range simply cannot offer at sea.

Mesh Intercom 3.0 keeps the group connected seamlessly without pairing or configuration. Open Mesh supports 6 channels with virtually unlimited participants; Group Mesh allows up to 24 in a private channel. Range up to 800 m on open water. Switch channels effortlessly, hands-free. And yes — you can mute your microphone. (We confirmed this directly with Sena; the distributor initially said otherwise. It’s possible.)

The low-profile over-ear design sits comfortably without blocking ambient sound — important on deck. Rounded arms grip securely, and the low neckband means hats, caps and sunglasses all work fine alongside it. At just 124 g, you’ll forget you’re wearing it.
