Ran some more brief tests with the GoPro external mic adapter and other mics. I tested each of these with the Hero 5 Audio setting set to "Standard Mic", and each has worked fine as long as the TRRS-to-TRS adapter was used. Note the one case of unexpected interference with the Rode VideoMic ME.
- Rode Videomic ME - Works decently for a small/tiny shotgun. Has some directionality, and decently strong rejection of sound coming from other than the direction in which it's pointed. My first test produced a fast-repeating, non-stop "click" heard along with the audio. During the test, I was wearing a Fitibit Blaze. On a hunch, I removed the Blaze and tested again. Sure enough, that fast repeating click was gone. It appears to have been caused by the heartrate monitor on the Fitibit, (i.e. that fast-flashing green light on the bottom of the Blaze). Keep that in mind if you use the Rode VideoMic ME. That was the only one of the mics I tested that picked-up interference from the Fitbit. I don't know if other heartrate monitoring devices would cause the same interference.
- iRigMic Cast - this worked fine, paricularly when the Lo-Hi switch on the mic was set to Hi. It recorded when set to "Lo", but the volume was noticeably lower. There was also a fair amount of sibilance, which I'm pretty sure is due to the mic and not to the GoPro external mic adapter. I don't have any kind of wind-screen for the iRigMic Cast, so there was nothing covering the mic itself.
- Insignia NS-MDMIC20 - worked fine, and produced decent to good audio, and even has some directionality. Overall, this mic worked better than I expected.
- Azden I-Coustics EX503i Lavalier Microphone - worked fine and produced decent to good audio.
I also did a test using a Rode SC6 dual-mic adapter. Extending from the Hero 5 Black, I had the GoPro external mic adapter. Into that, I had a TRRS-to-TRS adapter. Into that, I had the Rode SC6. Into the Rode SC 6 I had the Insignia NS-MDMIC20 directional mic and the Azden i-Coustics EX503i Lavalier mic. Sound was recorded to the Hero 5 Black from both mics. This all made for a relatively bulky setup and isn't something one would likely use too often, but it does provide a way to use dual mics as input, perhaps for a sit-down interview or whatever else one might think up. While I didn't run that test with 2 lav mics, the fact that it worked with 1 lav and the Insignia directional mic leads me to believe it would work with 2 lavs.
Of course, using a TRRS-to-TRS adapter plug also adds some weight and difficulty in handling the GoPro External Mic Adapter, making it a wee bit longer, but also more cumbersome, and does nothing to remedy the situation of not being able to use an external mic while the Hero 5 Black is attached to the Karma grip. Replacing the TRRS-to-TRS plug with the Rode SC3 adapter would add a couple more inches of "cable" to the "brick", making the entire setup even more cumbersome in execution. However, all these combinations did work with decent to good audio being recorded by the
Hero 5 Black.
