This headset was designed to give you a stable, secure fit for pretty much any kind of outdoor situation you might want to use it in - from helmet to helmet intercom duty to Bluetooth hands free calling.



A great fit for almost any situation.


Stays put while you’re playing.


This headset was designed to give you a stable, secure fit for pretty much any kind of situation you might want to use it in—from helmet-to-helmet intercom duty, to Bluetooth® hands-free calling, staying in touch with your companions in the great outdoors, or playing your favorite tunes from an MP3 player, you’ll always enjoy natural, crystal-clear sound quality. Bluetooth® music playback is controlled by Playback Control, and the sound is automatically boosted when operating in noisy environments.



Good to go under any conditions.

Impervious to water, sweat, and thinking twice.


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.



Share, talk, and have fun.

Share music. Make calls. Talk over intercom. 900-meter (980 yards) range.


Bluetooth® 3.0 technology provides the capability to listen to and share music, make phone calls, and participate in a four-way intercom conversation at a 900-meter (980 yards) range. Advanced Noise Control™ ensures noisy outside environments won’t interfere with use, and each audio source has its own volume level, which you can set to your preference. Meanwhile, integrated voice prompts will assist you with set-up and operation.


Compatibility between friends guaranteed.

Thanks to Universal Intercom™ protocol.


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