The problem with the TRRS input of my phone is that:
If you connect an earphone, the internal mic becomes unusable
If you connect a mic, the internal speaker becomes unusable
This is likely because the OS thinks you are using a combo
So the first step is buying this cable
Then I’ll have (hopefully) both the Sennheiser ME-2 and the Sony earphones working at the same time, and maybe that any mini-DAW can work
I’ll let you know
