I am trying to record high-quality audio on my iPhone videos. The internal iPhone microphone is not good enough for my purposes. I bought a Sony wireless (Bluetooth) microphone (ECM-AW4), and what I think is the right adapter so that I can plug it into the iPhone headphone jack. The phone can detect audio from this microphone for voice recognition in email or iMessage. But it does not record audio onto a video or into voice Memo. Has anyone been successful in getting audio to record from the headphone jack? What do you think I'm doing wrong? FYI, the adapter I am using is TRS (female)/TRRS (male). Thanks.
