Hello there TATER2937. Thank you for reaching out and for the inquiry. As A J posted on post #2 it would be best to use the official DJI propellers for your DJI Mavic Air 2 for compatibility and reliability purposes. Just a reminder that DJI do not recommend you to use a 3rd party accessories on your DJI Mavic Air 2 specially propellers. Propellers are the main components of the drone that should not be taken for granted when flying your DJI drone in terms of compatibility and reliability purposes. In addition using 3rd party accessories might cause damage or harm on your DJI drones and can void the warranty as well. Thank you for your understanding and fly safe always.
The DJI Mavic Air 2 props are already quiet in my opinion. The low noise props that come with it are designed to produce a lower pitched tone so they aren't as noticeable. Nice design indeed.
