Thanks Richard!
I plugged the mic directly to my Zoom H5. No audio signal at all. Then I plugged it to my GH5 and was only able to record left channel. I spoke to the mic for a few seconds then stopped talking so I can record the noise.
I brought it to Premiere Pro and used the loudness meter. I adjusted the overall volume level so that my voice would be in the “sweet spot.” When I stopped talking, you can see the loudness level of the noise (in red circle). I have no other mic on hand to compare it to except for another cheap one (Boya).

I think it’s noisy because the level is higher (but by just a bit) than the cheap Boya which is supposed to be noisy due to it’s cheap price.
