Connecting old iPhone headset to OP1 separate mic and audio jacks

Hello,

I have an old iPhone headset with the combo microphone and speaker going into one mini-jack. How do I connect it to the OP1?

I’m trying to have a very portable setup with the OP1 in a carrying case so I can listen and record my voice any time to make song sketches.

Thanks,

  • Joe

Would this do it?
