The only thing better than rippin’ down your favorite trail, hitting the climbs, or simply enjoying the mountain is doing it with your favorite music. The COROS EOSS audio platform allows you to stream audio while still being aware of the trail, and the natural sounds of the world around you. COROS SafeSound Mountain bike helmets offer a unique blend of safety, premium sound quality, and visibility. Our Impact Detection system adds layer of safety that will automatically notify up to 3 emergency contacts of your GPS coordinates, and provides a map pin of your location in the event of an impact to your helmet. Everything you need on the trail to ride Safe & Sound.
