Product Description
Product Code: KM-IPHONE-iM2

This adapter allows you to connect a microphone specifically for smart phones with 3.5mm (1/8 inch) 3-ring (TRRS) connector to the iPhone/iPad/iPod or other compatible device and allows for headphones to be used as well. This adapter is specifically for TRRS microphones that work plugged directly into the iPhone or other smart device; for standard microphones use our KM-IPHONE-2TRS or KM-IPHONE-2TRS-ECM adapters. This adapter also includes a 3.5mm stereo headphone jack which allows you to connect standard headphones. The headphones typically work for playback of recordings and not to monitor the microphone while recording unless you use a recording app with the monitoring feature (see FAQ section below for more details).

Types of microphones that work with this adapter:
  • Smart Lav
  • iMic
  • other microphones that are designed to be plugged directly into the iPhone or Android phones

Types of microphones that will NOT work with this adapter:

(For the following microphones, use KM-IPHONE-2TRS or KM-IPHONE-2TRS-ECM)
  • microphones that have a stereo or mono plug.

How it Works:

Plug the adapter into the iPhone (or other device) headset jack and then plug your TRRS microphone into the adapter. The iPhone will recognize that an external mic is connected and turn its internal mic off allowing you to record using the external microphone. This adapter works with all audio/video recording apps and other functions just as the internal mic would.

Plug standard headphones into the headphone jack to listen to recordings. The headphone jack normally works for listening to recorded audio only and not to monitor the microphone input while recording, unless you use a recording app that has a microphone monitoring feature.

Product FAQs:

Q: Why can't I use the headphones to hear (monitor) the microphone while recording?
A: The microphone signal is too weak to be heard in the headphones without being amplified. The mic signal would need to be amplified by the software (App) and played back through the headphones live for you to be able to hear while you are recording. Most recording apps, including the built-in recording apps, do not have a monitoring feature so the headphones will only work for playback of recordings with these apps. If you use a recording app with monitoring, like StudioMini or Fire by AudioFile, then you will be able to monitor while recording.

Compatibility List:

  • iPhone/iPad/iPod - all versions (Version 7 and newer require the use of a lightning to 3.5mm adapter)
  • Android Phones and devices
  • Samsung Galaxy phones and Cameras
Compatible with most mobile devices that use the combined 3.5mm headphone/mic connection.

Q; How do I know if this adapter will work with my phone or device?

A; Due to the massive number of new phones, versions and devices being released we are not able to test the adapter with all devices; however, if your device works with an iPhone headset (headphones and microphone) then this adapter will also work on your device.

  • Test your phone/device with a iPhone headset (perhaps try it with a friends iPhone headset)


  • Look up a new headset for your phone/device and check the compatibility list to see if it is also compatible with iPhone.
