Deity D4 Mini vs D4 Duo (Poorly recorded)

Update April 20, 2023: At the time this video was recorded, there was not a reliable measurement of audio gain using Filmic Pro App and Go Pro Hero 9. The audio was not properly normalized in post. The comments have been turned off and tags removed in hope that YouTubers will be saved from using this video as an accurate review.
