  "description_en": "Razer Nari Battery Level implements a USB HID exchange to read the headset's reported battery voltage through its dongle. The author captured SET_REPORT and GET_REPORT traffic and infers that two response bytes encode battery voltage in millivolts. A C program using libusb sends the requests and decodes those bytes.",
