I bought this set of propellers from china.   Very low noise and very stable in high wind condition.  In fact i was surprised during certain wind conditions, the mobile APP did not indicate high wind velocity !!

I'd love to see side by side photos of the new vs the old!

I'm VERY interested in making my spark quieter!

these are a commonplace 3rd party replacement prop. i have some. they make no difference in sound or flight performance.

They look the same to me, ill wait for some from DJI

Side-by-side would be good and a vid showing the noise levels would be even better

Actually it was good initially. Lately i noted  out of four sets of props, three sets  have become loose from the center guide pin. i don''t know what to make out of it and these days, there is heavy wind here. Need to test them again. '
Will keep you all posted.

DJI original props for me .. OEM is always best.  This has been my experience with many things in life.

There is zero redundancy on props when flying a quad. Just one of those becomes loose during flight and you may be looking for a new drone. Not worth it. I never use any third party props, chargers or batteries on any of my drones and don't even use landing gear extensions. None of it has been tested by DJI.
