The Cavalry comes pre-wired and ready to go with built-in Bluetooth capabilities and controls, so users can enjoy all of the great features of Sena’s communication devices without the hassle of installing a headset. Chat with your buddies over the intercom system or take calls directly through your helmet with the built-in microphone for crystal clear conversations, and hear your music louder and clearer than ever before thanks to the built in half-helmet speakers on each side along with optional ear cups to boost the audio level while you’re out on the open road.
The technology included in this revolutionary helmet is our most up to date Bluetooth® 4.1 features, so you can keep the chitchat going, share a playlist with another riding companion, listen to FM radio, or patch in your friend over the half-helmet intercom while you’re on a phone call. The Bluetooth half-helmet does it all with top notch sound quality and Sena’s Advanced Noise Control™ Technology at ranges of up to 900 meters (0.5 miles) for 10 hours of Talk time.
