In addition, MyHeadset Updater enables you to set certain options for your headset, such as the preferred language for voice prompts and commands, as well as toggling the Smart Sensors on and off. Note: You must have access to a Windows PC in order to perform the update. If you do not have access to a PC, we will be happy to replace your headset with one that has the latest firmware.
