it is completely ignoring the fact that the Sennheiser is attached. I've also done a simple experiment to confirm that the MacBook is indeed receiving audio from the built-in microphone. It states "Internal microphone/Built-in" regardless. System preferences -> Audio -> Input does not change when I plug and unplug the splitter (which has the Sennheiser ME3 attached). However, audio input does not behave correctly. I also check that audio output works correctly TRRS -> splitter -> my headphones. I also note that actually plugging and unplugging headphones into the other end of the splitter doesn't register. The first check I do is on the headphones: I go to System preferences -> Audio -> Output, and notice that inserting the splitter registers as "Headphones/Headphone port" whereas removing it registers as "Internal speakers/built-in".

(this is so that I can use speech recognition software - the Sennheiser is especially good for speech recognition)

I am trying to get an external microphone ( this Sennheiser ME3) into the TRRS jack of my 2012 MacBook Air, through a headset splitter such as here.
