This adapter allows you to connect a standard electret condenser microphone (EMC) with 3.5mm (1/8 inch) connector to the iPhone/iPad/iPod or other compatible device for quality recording. This adapter is for use with ECM microphones that do not have batteries and will allow the phone to power the ECM microphone. This adapter works with ECM microphones that have a mono or stereo 1/8” (3.5mm) connector.

Types of microphones that work with this adapter:
  • ECM Microphones that require 2 VDC plug in power.
  • Lavaliere ECM Microphones (without batteries)
  • ECM PC Microphones
  • ECM Headset/boom Microphones

Types of microphones that will NOT work with this adapter:
(For the following microphones, use KM-IPHONE-MIC)
  • Dynamic Microphones
  • Lavaliere microphones (with batteries)
  • Wireless microphone systems

How it Works:
Plug the adapter into the iPhone (or other device) headset jack and then plug your 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.

Product FAQs:

Q: Will this adapter work with a stereo mic?
A: The combined headset jack on the iPhone and other devices only has a mono mic input so you cannot record in stereo. Most recording apps split the mono signal into both left/right channels when recording so the audio will play back in both ears. You can connect a stereo mic to this adapter but only one side of the mic will be active; if you use a stereo-to-mono adapter on your mic then it will make both mics active. There is a new stereo microphone product available which will allow for stereo recording using the docking connector; this is currently the only option available for stereo recording, Tascam IM2 stereo mic.

Q: Why do I need a different adapter for a mic that has batteries?
A: Lavaliere mics, PC mics and headset mics are typically ECM mics (electret condenser mics) and all ECM mics require power to operate. If your ECM mic does not have batteries then you need the –ECM version of the adapter which allows the iPhone (or other device) to power the mic. If your mic has batteries or is a dynamic mic or wireless mic then you need the KM-IPHONE-MIC version of this adapter which blocks the power from the phone to prevent damage to the mic.

Q: Can I connect a microphone with a different style connector if I use an adapter?
A: Although you can adapt various microphone connectors to work with this adapter, the XLR connection needs to be hooked up as “Unbalanced” and most XLR to 3.5mm adapters are balanced connections. You can either use our XLR version of this adapter, or you can connect an XLR mic to this adapter by using an XLR to 3.5mm mono (unbalanced) adapter.

Q: Can I connect two microphones for doing interviews?
A: Yes, you can use a standard 3.5mm splitter adapter to connect two microphones which will combine the signals from both microphones into this adapter. Alternately, you could use a small mixer to combine the signals from multiple microphones into this adapter.

Not Compatible with some devices using the combined headset connection like versions of Motorola Droid phones and earlier versions of the Samsung Galaxy phones. and; some Manufacturers use a different method for wiring the headset 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.
