Founded in 2003 by Mike Sena, a former professional motocross rider, the brand emerged from a personal need to communicate with his racing team without the distraction of bulky wired headsets. Initially gaining traction in the off-road and dirt track communities, Sena revolutionized the market by integrating Bluetooth technology directly into motorcycle helmets, creating the first truly wireless intercom systems for riders. Their early success was driven by the Sena SMH10 series, which set a new standard for audio quality and ease of use, quickly expanding from niche racing applications to mainstream touring and sport riding.
