The Pro Pro 3.5mm Mic Adapter from GoPro allows you to record high-quality clean audio from an external source with your GoPro. It's compatible with the HERO9 Black, HERO8 Black, HERO7 Black, HERO6 Black, HERO5 Black, and HERO5 Session.

A 3.5mm analog stereo input can accept mic or line-level signals, and is compatible with powered and unpowered microphones. So whether you want to plug in a shotgun or lavalier mic for interviews, or take a signal directly from a music venue's mixing console, this adapter will come in handy. The internal A/D (analog to digital) conversion has 106 dB of headroom, ensuring a clean audio recording. While the adapter takes up the camera's USB port, a pass-through USB port is available on the adapter, so you can still charge your camera with the adapter plugged in.
