Solved! plug audio cable into iphone 6 and external cassette recorder

Apr 11, 2018
I am a private investigator and I need a setup to record witness telephone interviews using my iPhone 6 and an external microcassette or digital recorder. I need an audio cable that has a male TRRS jack on one end for the iPhone and a standard 3.5 jack on the other end for the recorder.
Another reason to skip analog - Once you plug said cable into the phone, you'll no longer hear the conversation, you have to find a way to listen thru the recorder.
