Step forward the leaner (but not meaner) DJI Mini – a wireless mic that doesn't record – the sound goes straight into your iPhone/Android phone as you record and straight onto the video?

If you’re using the Mic Mini with a GoPro, Insta360 or smartphone camera, you’ll want to buy an RX + TX bundle and connect the RX to your camera using a TRS cable or USB-C/Lightning connector.
