Audio Solutions Question of The Week: Can I Use My Microphone with an iOS or Android Device?

Question: Can I use my microphone with an iOS or Android Device?

Answer:  As we often say, the answer to so many questions in the audio world is “It depends.” And that’s the short (and, perhaps, not very satisfactory) answer here as well. The reason it depends is that although 3.5 mm (⅛”) microphone connections are the same size, the connections themselves are not created equal.

When you plug a microphone into a device such as a mixer, computer, or recorder, you always need to make certain that the specifications of the microphone and the other device are compatible. For example, while the 3.5 mm connection on an iPod and iPhone look similar on the outside, they are different on the inside. The iPod has a standard TRS (tip-ring-sleeve) connection that connects to headphones (TRS: audio left, audio right, ground, respectively). Other devices such as iPhones, iPads, and Android phones/tablets have a TRRS (tip-ring-ring-sleeve) connection. Therefore, if you plug a TRS device (such as a 3.5 mm microphone) into a TRRS device (such as an iPhone), the connection will not work properly. To further complicate things, there are two major standards for TRRS used with smartphones: Standard CTIA and Standard OMTP. Apple and CTIA, the wireless industry association, worked together to create the CTIA connection (shown below). With the popularity of Apple’s iOS devices, most other devices on the market now likewise use the CTIA pinout. For comparison, we show the OMTP standard, which is less commonly used today.

That’s enough technical jargon for now – let’s get to the microphones!

If your microphone isn’t specifically designed to be connected to an iOS or Android device, the solution is to use a proper adapter, which is a TRS (female) to TRRS (male) adapter. There are also some after-market, in-line TRRS adapters available that let you connect a microphone with a 3.5 mm plug to an iOS/Android device. The TRRS adapter will make the proper conversion. Again, always check the compatibility of all the devices involved before using.

Audio-Technica has already done the work for you and designed some popular microphone choices to connect to your iOS or Android device:

  • The ATR3350iS microphone is the popular ATR3350 microphone with an included smartphone adapter. The “iS” version of this product allows you to plug the ATR3350 microphone into the in-line adapter, then into the iOS or Android device. The adapter does all the proper adapting and conversion so all you have to do is plug it in and start recording.
  • The NEW AT2020USBi, debuting this week at the 2015 NAB Show and modeled after the very popular AT2020 microphone, includes not only a USB connection, but also a Lightning connection that plugs directly into an iOS device. This allows you to use the widely acclaimed studio microphone on the go with your favorite iOS device applications.

We hope this post helped clear up any confusion about microphone compatibility with iOS and Android devices. But if you need more clarification or need assistance with any of your Audio-Technica gear, please don’t hesitate to contact our Audio Solutions Department. And be sure to check back next Wednesday for another “Question of Week.”



  1. Hi–Is there an omnidirectional standing mic that can plug into iphone?

    • Hi Sue,

      Yes, you may use the ATR3350iS listed in the above blog with your iPhone.

  2. Hi all,
    I wanted to use the ATR3350iS to run a line from a mixer to my iphone mic plug but wanted to make sure it was ok, looks like the adapter is stereo on both sides (TRS) and the iphone is a mono mic (TS)?

  3. Hello, I’ve got the AT2020USBi and I’d like to use it directly with my iPhone 6.
    So I plug it but it doesn’t work, what can I do?

  4. I have I wanted to use the ATR3350 without iS.

    How can I use this to record sound in my android phone?

  5. I wanted to know if someone knew where I can buy a lighting connector/connection for my audio technica at2020

  6. i have a mixer with RCA record output. but i cannot directly record to my android by using RCA to TRS cable. If i use splitter cable that has seperate mic input can i be able to record with my android?

  7. I have a huawei y635 smartphone, what type of trrs connector do i need for adding an external mic to my phones headphone socket, because i heard moto and huawei use different trrs than iphones etc ?

  8. I read all of the above but I I cant get the ATR6550 to work on my iphone6s. I purchased this shotgun microphone and a 3.5mm Stereo TRRS/Male to TS Jack Microphone to iPhone Adapter w/ DC insulator Ip-MIC4.
    When I test the microphone on my iphone, I don’t hear any sound quality difference compared to my built-in microphone on my phone6s.
    I don’t know if the shotgun microphone is defective as there is no light indicator to indicate the microphone is ready when I turn it on? Have I gotten the wrong adapter for my iphone?
    Thank you in advance for your help in resolving this issue.

  9. Hi there, similar question to Soke’s but I am using it it for the app FimicPro, which claims to be compatible with any mic. Both my AT8010 and AT8035 work fine with any other recorder but my iphone 6s doesn’t seem to recognize them. I use the Rode SC4 TRS to TRRS adaptor – this works fine with my ATR3350. The phone does recognize my AKG dynamic mic when I use it with the same cable that I use for my AT mics. Any idea why this happens?

  10. Thank you for the information. I am interested in recording bird sounds on my cell phone from a distance.Which mic would give the best sound quality? I have used a shotgun mic with decent results but is something better? thanks

  11. I want to use the ATR3350iS with my Samsung S5 and Wonderboom to amplify my speaking voice in a conference setting where there is no tech available other than these devices. The set up creates too much latency and the echo is distracting to the audience and speaker. A wireless audio transmitter was purchased to reduce latency but it has to be connected to TV, projector or computer which then makes the ATR3350iS device wired. I cannot carry around a laptop whilst speaking.
    How can I reduce the latency using the ATR3350iS device for this type of use. What apps do you suggest.

  12. Hi.

    i do have ATR3350iS., the adaptor work fine with my android unit but not with Iphone6s, it will use phone internal microphone instead.

  13. I have a new ATR 3350 Is and the adapter to iphone and ipad is not working. The system dont recognize the new mic and still record using the in built microphone. I need change the adapter? note: I test de microphone in my Canon SLR and work fine. Conclusion: the adapter is the problem. Any solution?

  14. Hi. I have the ATR3350iS and I wanted to convert the mini jack to XLR. May I know the pinout for the mini jack? Thanks!
