Review on Sena 50S Bluetooth Headset: Premium Quality Single Headset for Ultimate Connectivity by Gregory Flynt

Straight out of the box, could never get 50S to connect to any Bluetooth device, got it with iPhone 12, MacBook Air, iMac tried. Used Sena for iOS Phone App (Rated just over 2 stars in the Apple App Store), user manual is only available online and does not come with the device. English is a difficult translation to understand. The keys are indistinguishable, unsuccessfully localized. The box was good. Perhaps they need to spend less on packaging and more on instructions, design, and software.
