SEAMLESS DESIGN FOR EASY HANDS-FREE COMMUNICATION

The built-in speakers are fully integrated and recessed above your ears, meaning no obtrusive headphones – this open-ear design allows awareness of your surroundings on the trail even as you listen to your music or chat with friends. The integrated microphone features Sena’s patented Advanced Noise Control™ technology, reducing unwanted wind noise.

CONNECTED ON THE JOURNEY WITH BLUETOOTH® INTERCOM

The M1 features four-way Bluetooth® Intercom, letting you communicate with other riders wearing a Sena Bluetooth-enabled helmet. Up to four people can connect and converse on the trails within a range of up to a half-mile. The helmet also includes 2-way HD Intercom; a couple of friends connected get to experience high-definition sound quality in their conversations! The M1 provides a hands-free talking experience without the need for cell phone service or data usage.

*Note: The M1 Bluetooth Intercom Helmet is not compatible with the M1 EVO Mesh Intercom Helmet

BUILT FOR SAFETY, COMFORT, & STYLE

An integrated LED taillight dramatically increases your visibility to those behind you, while the included sun visor reduces sun glare. The numerous vents on the helmets enable airflow, keeping your head cool while an adjustable nylon chin strap couples with the spin-lock adjuster to comfortably fit and stabilize the helmet on your head. M1 helmets are available in Medium and Large sizes in three different colors: matte black, matte white, and cement gray.

CONNECT TO YOUR SMARTPHONE FOR AN ENHANCED RIDE

By pairing your smartphone to the helmet via Bluetooth connectivity, the M1 allows you to hear GPS navigation, take phone calls, hear fitness app cues, and listen to your favorite tunes.

THE SENA UTILITY APP ENERGIZES YOUR RIDE

The Sena Utility App allows you to take control of the M1’s features. Through the app, you can enable groups of intercom friends to easily connect with one another and access the product Quick Start Guide on the go. You can also use Smart Intercom Pairing in the app to quickly scan a QR code on a friend’s phone and instantly pair your helmets to each other!
