I'm flummoxed on the correct cable for the following set-up. I have the latest iPad Pro, with the single USB-C port of course, and I am using a USB-C hub to use headphones and charge. There are other USB-C and USB ports if I need them. works fine with the standard iPhone/iPad headphone and mic, but audio quality is terrible and there is noise. I have a male 3.5mm clip-on microphone and a nice pair of studio quality headphones, also male 3.5. my project is recording tutorials for video music apps with narration. I am recording everything to the screen capture on the iPad and then to MP4. I've been through the Amazon adventure twice and both times the cables I bought failed to live up to their descriptions. can anybody out there point me in the right direction for the right adapters? thanks in advance.
