Full-Duplex Sena Expand-02 Headset

Communication for any Adventure

This water-resistant Bluetooth® headset was designed to give you a stable, secure fit in any situation. Use the Expand to communicate from headset-to-headset (up to 4 people), take hands-free phone calls, or listen to music from your smartphone. No matter the situation, you’ll always enjoy the crystal-clear sound quality.



Ready to Go, Rain or Shine

Built to be water and sweat resistant, you won’t have to think twice about keeping your Expand headset on your head as the weather rolls in. The Expand is the only Bluetooth headset with water-resistance of its kind.

Chat Headset-to-Headset 900 m/980 yards Away

Bluetooth 3.0 technology allows for four-way intercom over a 900-meter (half-mile) range. Advanced Noise Control™ ensures noisy outside environments won’t interfere, and each audio source has an adjustable volume level, which can set to your preference. Meanwhile, integrated voice prompts assist you with set-up and operation.

The Compatibility You Need

Even if your companions don’t use Sena gear, Expand uses the Universal Intercom™ protocol, which makes your equipment compatible with theirs, regardless of brand.

These headsets are perfect for onboard crew coordination. Having a communication system onboard is often referred to as "Marriage Savers."


These headsets are great for other applications like:

  • Cycling
  • Hiking
  • Kayaking
  • Canoeing
  • Full multiplex conferencing (up to 4 team members)

There is no competitive product offering comparable value with all of these features.

NOTE: Units sold individually.  Two headsets required for a 2-Way system.
