The DJI Mic and Mic 2 wireless microphones have quickly established themselves as staples in the video industry; I can't binge YouTube for more than three or four videos without seeing one of them, and if not a DJI one then the competitor Røde Go.
The principle is simple; a digital wireless microphone that plugs into the recording device to record clean audio AND records sound onto its own built-in memory at the same time for safety. Personally it was this device that caused me to finally abandon my near decade-old Zoom recorder in my workflow.
