COMICA VM10 PRO Universal Video Microphone - Adjustable Gain, USB C Digital Output, Monitoring - Shotgun Mic for Camera, Smartphone, Tablet, PC - Ideal for Vlogging, Live Streaming, and Recording

You can spend a lot of money or a little money - and still get pretty good results! I bought a pretty inexpensive microphone from Comica that I’m happy with (for the price); no, it’s not a Sennheiser or an Audio Technica or a Shure like I used to use on film sets, but it works and I think it would be a really flexible option for what you are describing. I use this one which has an Analog/Digital switch: https://www.comica-audio.com/product/VM10-PROBecause of the switch, when you slide the switch to Digital, you can use the USB C to connect to phones and computers. Then, because you’re using a HERO7, you can connect it using the 3.5mm connector with the switch slid to Analog. (You will need to get the GoPro specific adapter to connect it to a HERO7, FYI.). Since you’re doing that, you might want a cage that can hold the GoPro mic adapter at the bottom and the microphone in a cold shoe at the top of the camera.Here is an example of this: https://a.co/d/0g45x0QEHere is the GoPro mic adapter: https://a.co/d/0a0ZdVXYHere is the microphone: https://a.co/d/0fHeqPs1 I hope this is helpful!
