I can't get my dynamic microphone to work on my MacBook Pro. How do I go about it?

I have a speaker, headphone splitter and a 3.5 mm male-to-female audio cable.

Still, I cannot recognize the microphone on the MacBook. Any suggestion ?

    The pinouts are completely wrong [even the visible number of bands don't match]. See CableChick - Understanding TRRS and Audio Jacks for some grounding in the subject. You'll need the manual for the mic to know what that very odd plug is supposed to do. Is it meant to be stereo [or even less likely, balanced line]?

  • @Tetsujin, Yes it is supposed to be a stereo jack for the mic.

  • I can see it's a 'stereo' jack, TRS… that doesn't actually explain its function, which is why I asked.
