How to get audio input through 3.5mm on MacBook Air

For a conventional mic, are you using a TRRS adapter for the 1/8 mic cable? If not, you are gonna need one.

The single audio connection is simultaneously both an input and an output, much like the audio jack on an iPhone (3.5 MM TRRS Tip Ring Ring Sleeve Connector). The adapter you want to use is a mini-jack with the 4 conductors (TRRS Male) that will adapt to a conventional microphone jack.

Something like this:

Maybe you can help me now? 🙂

I have a iPhone 1/8 inch microphone adapter - 3.5mm 4 conductor TRRS Male to 3.5mm Microphone Input Jack from here. that allows me to plug my lapel mic directly into my iphone and record, it is great.

I was hoping I could also use it on my MBPRetina to accomplish the same purpose. Do you know if that is possible? I tried and tested it recording a video in iMovie, and didn't notice any change.

I went to the Sound Input Preferences, and do not notice the mic input changing when I plug it in or remove it. In other words, it always says "internal mic."

My lapel mic is battery operated, with a fresh battery, and it was turned on.

What am I doing incorrectly? Any help would be wonderfully appreciated!

Did you ever get a resolution to using a 3.5mm 4 conductor TRRS Male to 3.5mm Microphone Input Jack for a MacBook Air? Ever get it working? Thx.
