p 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 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

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.

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.
