Cynova not cynova adapter
Feelworld FM8 microphone

Has anyone tried these and if so do they work and if so how'd they do?

Thanks in advance

Hello there JodyB. Thank you for reaching out and for these information you have posted. I hope that you will get the best information you need from our fellow DJI members who have purchased and used these accessories on there DJI Osmo Action. Just a reminder to use the CYNOVA Osmo Action Dual 3.5mm/USB-C Adapter and the recommended microphones for your DJI Osmo Action for compatibility and reliability purposes. Thank you.

Not personally - will be good to see if others have

I have not tried them.

I will be trying them out when they get delivered today. I’ll let you know if they work.

I like the reviews of this Sarmonic mic as well. They have them at the Best Buy thats closest too me, too bad thats about 1.5 hours away though. Very comparable to the rode videomicro according to the reviews. Priced the same, just doesn't come with a dead cat wind screen, but does come with both TSR and a TSSR cables. I've got the Feelworld FM8 coming in today from Amazon, so hopefully that with the audio usb c adapter I have coming will work and if I'm not happy with the FM8, I may go get the Saramonic for BB.

I just got these in and they work great. So anyone looking for a cheap way to add a mic to your OA this is a good way to do it.
