We tested DJI’s new quieter props for the DJI Phantom 4, and yeah, they make it much quieter – about 5 to 6 dB quieter. The pitch is overall better, too. If you like being discreet, these help… basically, you’ll annoy your neighbors slightly less than before.
We also tested the Phantom 4 Pro with the new props against the DJI Mavic Pro with the platinum props. The Mavic is still the overall quietest drone, thanks to its lighter weight and smaller size.
