I tested a ZOOM AM7 Mid-Side microphone for Android, by inserting it inside a 53 cm diameter paraolic disc, using a USB-C Male/Female cable. For this Recording the REC Volume wheel was set almost to its maximum, at the 9 of 10 Level position, so part of the background noise is due to the very high setting. There is a bit of handling noise.

Below are some pics of how I made, through 3D printing, the casing to insert the ZOOM AM7 Mid Side microphone.
