The new 50S and 50R communication systems offer the next level of robust intercom connectivity through Mesh 2.0 and 5.0 Bluetooth® connectivity. An open mesh intercom function with multiple channels is a global premiere for the new communication sets. At the heart of the enhanced audio experience are the redesigned HD speakers. The fast charging of the battery is now 30% faster and therefore there is no excessively long waiting time until the next journey. Voice commands can be recognized in 8 native languages (CHI, DEU, ENG, ESP, FRN, ITA, JAP, RUS). There is also direct access to digital assistants for iPhone and Android using voice commands such as \"Hey Siri\" or \"Ok Google\". The WiFi feature provides automatic firmware updates, as well as future surprise enhancements. A brand new mobile app gives drivers an intuitive way to get the most out of their 50S and 50R. The Sena 50S retains the proven jog dial design, while the Sena 50R offers the driver a slim option.
