Dear Apple Community,
I cannot figure out why my external microphone (via audio jack) is not listed in the Input settings.
When I use the audio cable with my headphones (Bose QC I) the input device (External Headphones) is not listed in the sound menu, however when I activate bluetooth on my headphones then the microphone is listed and working.
Can you help me to use my headphones as an external input source when I connect them via audio cable?
Thanks!
MacBook Pro
My MBP 13" is from 2018. If an audio jack is present it is mostly common that it supports line-in - I never heard of a case where the audio module (hardware) is made in such a way that it does not support microphones.
I think I found the answer why a line-in does not show up:

My earphone jack has 2 pins (stereo), while a 3 pin audio jack would indicate that it also transfers the mic input.
Although I could have sworn that it used to work some months ago...
The audio jack is out only.
What year is your Mac? Apple removed the Line In jack many years ago. Since you posted in the Catalina community, I assumed it was new enough to run Catalina. The video you posted is using an older Mac with a line in.
Sorry, I thught you were taking about a separate mic. and yes, you are correct, it has the wrong jack.
Audio Input not listed anymore
