Product Description


This adapter allows you to connect a standard microphone with a 3-pin XLR connector to the iPhone/iPad/iPod or other compatible device for quality recording. This adapter incorporates passive components which provide DC blocking/isolation between the microphone input for device protection, as well as, impedance matching components for allowing a wide variety of microphones and instruments to be used with the device. This adapter works with Dynamic microphones, wireless microphones and battery powered condenser microphones. This adapter will not work with microphones that require phantom power, unless you connect a phantom power supply inline with the microphone.

This adapter also includes a 1/4 inch 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).

This adapter uses a slim 3.5mm TRRS headset plug which will fit through most phone protective cases so that the case need not be removed when using the adapter.

The length of the microphone cable is optional from 3 feet to 10 feet; select the optional length prior to adding to the cart. The default length if you do not select a different length will be 3 feet. The length between the headset plug and the headphone jack is about 3 feet and this is a fixed length no matter which length you choose for the microphone cable.
This cable will work with all versions of the iPhone/iPad and most Android phones. When using it with iPhone 7 or newer phones that do not have the headset jack, use the lightning to headset converter cable that comes with the phone - see picture above.
Types of microphones that work with this adapter:
  • Dynamic Microphones
  • Battery Powered Condenser microphones
  • Battery Powered Lavaliere Microphones
  • Wireless Microphone systems
  • Condenser microphones (when an external phantom power supply is used)
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.

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: 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.

Q: Why is an external phantom power supply required for condenser mics that do not have batteries?
A: All condenser microphones require power to operate. Some condenser mics supply that power from batteries and some require phantom power from the device they are plugged into. Since the iPhone cannot supply the required phantom power, a portable phantom power supply must be used for these types of microphones.

Q: Can I connect a microphone with a different style connector if I use an adapter?
A: Yes, You can use adapters to connect microphones with 3.5mm or 1/4 inch connectors providing they do not require phantom power.

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 Garage Band, then you will be able to monitor while recording. For monitoring video recordings try FilMic Pro.

Compatibility List:

Compatible with most mobile devices that use the combined headphone/mic connection.

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.
