The Jabra Evolve 80 is designed to be compatible with smartphones and tablets via the jack-plug that connects to the USB-controller. As the number of smartphones and tablets with USB-C are increasing, Evolve 80 USB-C users might also want to connect the headset to their personal devices. In most cases this should work seamlessly, but for some certain mobile phones and tablets, there might be a compromise in the performance of audio and remote call control functionality (e.g. answering, ending call, muting). For this reason, and to set the right expectations for our end users, we have added a note about this in the Evolve 80 Quick Start Guide, as well as on the packaging itself – using the sticker depicted on the left.
