The 50R now offers an even more premium audio experience with SOUND BY Harman Kardon. Both the speakers and microphone were created with the audio experts at Harman Kardon to provide world-class sound for one of Sena’s most popular devices. Expertly crafted speakers and an all-new microphone allow the 50S to deliver an unmatched audio experience. The speakers send crystal clear audio to riders’ ears while the microphone, with a newly designed sensor, provides robust performance for voice communication while riding.


Take control of the 50R without lifting a finger. Voice commands give you hands-free control of the 50R, operating select functions, including entering Open Mesh or answering a phone call. Simply say a command, and the 50R will act for you. The 50R supports multi-language voice commands, responding to eight different languages, including English, French, German, Spanish, Italian, Chinese, Japanese, and Russian.

The most powerful upgrade to the 50R voice commands is the new direct, hands-free access to Google or Siri through your smartphone! “Hey Siri, directions to the nearest hotel, please!” “Hey Google, what’s the weather forecast for Sturgis today?” No buttons, no other preliminary commands. The 50R connects to everything Google Assistant and Apple’s Siri have to offer…all while you’re rolling down the highway! Access phone numbers, music apps, or even ask for directions to the world’s largest ball of twine (it’s in Cawker City, KS by the way)! Riding Connected couldn’t be easier.
