How To Use External Mic And Internal Speaker
The cameras on smartphones are continuously improving while the microphones remain functional merely low-quality. When recording a video with your telephone, information technology'south nice to have excellent audio to get with the astonishing picture, which is where external microphones come into play.
So how do we connect an external microphone to a smartphone? Connecting an external mic to a smartphone must be down wirelessly (Bluetooth) or through one of the connectors (typically the headphone jack or the charger port). Additionally, some drivers/software may be required to consummate the connection.
In this commodity, we'll go through the diverse methods of connecting external microphones to smartphones and some recommended smartphone microphones.
Note that this article features links to products on Amazon that volition help you lot connect your external microphone to your smartphone. Ownership whatever product through the following links will requite me a commission (and aid support this weblog) at no extra price to yous!

Connecting An External Microphone To A Smartphone
And so we've decided that the internal smartphone microphone just won't cut it, and nosotros'll require an external mic for our phone's audio recording. Let'due south go into the details of connecting.
For more data on internal smartphone microphones, bank check out my article What Kind Of Microphones Are Used In Jail cell Phones?
First, it's important to note that smartphones, like computers, are digital devices and work with digital audio. Whether internal or external, microphones produce analog signals that require analog-to-digital conversion to properly connect and ship information to a smartphone.
These analog-to-digital converters (ADCs), as nosotros'll discuss later, are institute inside the smartphone (just inside the TRRS headphone jack or within the Bluetooth chip) or, alternatively, in adapters that allow us to digitally connect our mics straight to the phone (often via the charging port).
To read about analog and digital signals and microphones in more particular, check out my commodity Are Microphones Analog Or Digital Devices? (Mic Output Designs) .
At present that we've established the need for digital audio let's expect at the methods of connecting external mics to smartphones.
At that place are 4 basic methods of connecting an external microphone to a smartphone:
- Connecting wirelessly via Bluetooth
- Connecting directly via the TRRS headphone jack
- Connecting wirelessly via the TRRS headphone jack
- Connecting via the charger port
Connecting An External Microphone To A Smartphone Via Bluetooth
Bluetooth technology has been available in mobile devices since 2001 and has since seen a massive increase in popularity. Now, all smartphone comes with Bluetooth capability.
Bluetooth is simply a wireless data protocol that uses short-wavelength UHF radio waves (in the 2.400 to 2.485 GHz range) to transfer data and signals over brusk distances.
Bluetooth mics piece of work like whatsoever other wireless mic arrangement: with a transmitter (either within a Bluetooth microphone or externally connected to a microphone) and a receiver (a "Bluetooth chip" found within Bluetooth devices/receivers).
Connecting a Bluetooth mic to a smartphone is easy. Take the post-obit steps:
- Plow the Bluetooth microphone or Bluetooth mic transmitter on
- Open up the Bluetooth card of your smartphone and ensure the telephone is discoverable
- If the devices are within range of ane another, the mic should show up as a device
- Click the microphone in the Bluetooth devices list to connect the mic to the smartphone
With Bluetooth connections, at that place are two main ways to connect microphones to smartphones:
- With a Bluetooth microphone (with the Bluetooth engineering designed into it).
- With a Bluetooth microphone transmitter (which allows a regular wired mic to transmit wirelessly via Bluetooth).
Bluetooth Microphones
Bluetooth microphones are relatively new on the market. These mics take built-in Bluetooth transmitters and are ofttimes inexpensive mics with electret mic capsules.
Bluetooth mics make information technology easy to connect wirelessly via Bluetooth to smartphones and other Bluetooth devices.
At a Buskers festival I had recently attended, I noticed that every performer was using a Bluetooth clip-on mic or headset.
Bluetooth microphone example: Hey Mic!
You can buy the Hey Mic! directly from their online shop at a ten% discount past using the promo code mynewmicrophone
The Hey Mic! (pictured to a higher place) is one example of a Bluetooth microphone. This miniature microphone is compatible with any Bluetooth device and offers upwardly to 65 feet of range.
Notation that, while Bluetooth microphones are an excellent idea, the engineering isn't quite perfect just withal (the audio industry is always behind on technology). That being said, the Hey Mic has decent reviews and works largely how nosotros'd expect a Bluetooth mic to piece of work.
XLR-Bluetooth Transmitter
If we want to utilize a professional microphone via Bluetooth, there are XLR-Bluetooth adapters/transmitters on the market.
With these transmitters, we can combine the loftier-quality mic capsules of our favourite mics with the simplicity of a Bluetooth wireless connection. Connect your XLR microphone to the Bluetooth transmitter so link the transmitter and the smartphone.
We must presume that these transmitters practice not supply any DC bias voltage or phantom ability to our microphones unless noted and so (I accept non plant any on the market that do). Therefore, using passive dynamic mics is the safest bet when connecting an XLR mic to a Bluetooth microphone transmitter.
XLR-Bluetooth adapter/transmitter example: JK Audio BlueDriver-F3 (link to check the price on Amazon).
XLR Bluetooth Transmitter
The JK Audio BlueDriver-F3 is a simple XLR-Bluetooth adapter/transmitter. We connect our mic to it; turn it on; suit the connection settings (to phone), and brand the Bluetooth connection.
The BlueDriver-F3, as I alluded to before, does not supply DC bias or phantom ability, so it should simply exist used with passive microphones (think dynamic mics).
For information on connecting Bluetooth mics and other wireless mics to computers, check out my article How To Connect A Wireless Microphone To A Computer (+ Bluetooth Mics) .
Connecting An External Microphone To A Smartphone Directly Via TRRS Headphone Jack
Using the jack of a smartphone is possibly the almost obvious method of connecting an external microphone.
Merely await, the headphone jack outputs bespeak while a microphone inputs bespeak. Allow's take a closer wait at the wiring.
Smartphone headphone jacks are typically designed as 3.5mm (ane/8″) TRRS (Tip-Band-Ring-Sleeve) female telephone connections.
Though there are two wiring standards (CTIA and OMTP), these 4 connections (TRRS) are typically wired equally CTIA. Apple tree was a major role player in developing the CTIA standard (with CTIA, the wireless industry association), and now the vast bulk of smartphones follow the CTIA standard.
The CTIA standard has the TRRS connection configured as follows:
- Tip: Sound (left)
- Band: Audio (correct)
- Ring: Ground
- Sleeve: Microphone
The OMTP has the microphone and footing switched, and and so it'southward important to know the divergence. That being said, the vast majority of devices with TRRS designed to work with smartphones follow CTIA.
All this is to say that if we want to connect a microphone to a smartphone headphone jack, we need to use a 3.5mm (1/eight″) TRRS male phone connector. Because the microphone indicate is carried on the sleeve, 3.5mm (1/eight″) TS and TRS cablevision volition not work (though they will physically fit into the jack). This is because TS and TRS cables are wired with S (sleeve) as footing.
To convert a one/8″ TS or TRS mic connexion to a 1/8″ TRRS connection, I'd recommend a headsets splitter adapter, like this one from DuKabel (link to cheque the price on Amazon).
The Dukabel headphone splitter is wired equally CTIA and has a microphone and headphone input that adapts to a TRRS for connecting to the smartphone.
The i/8″ TRS microphone jack volition have mics with TS and TRS connections. The i/8″ TRS headphone jack volition allow you to monitor the microphone (the smartphone will likely use the TRRS connection equally the audio input and output).
Just at that place are TRRS microphones on the market place that will easily bypass all the adapters require in connecting a regular mic to a smartphone via the headphone jack.

• Differences Between 2.5mm, 3.5mm & 6.35mm Headphone Jacks
• How Do Headphone Jacks And Plugs Work? (+ Wiring Diagrams)
TRRS Microphones
TRRS microphones are designed to plug into and send audio through headphone jacks. These mics, therefore, piece of work wonderfully with smartphones.
TRRS microphone example: Rode smartLav+ (link to bank check the price on Amazon).
The Rode smartLav+ is a relatively high-quality lavalier microphone for use with smartphones. Information technology follows the CTIA standard, powers itself from the smartphone'due south TRRS jack (2.7V), and works well with any recording software.
The Rode smartLav+ is featured in My New Microphone's Top four All-time External Microphones For Android Smartphones.

XLR-TRRS Adapter
If we desire to utilise our professional XLR microphones with our smartphones, nosotros'll need an XLR-TRRS adapter.
XLR-TRRS adapter instance: Saramonic XLR 19.5′ XLR-TRRS Adapter Cablevision (link to bank check the price on Amazon).
This unproblematic adapter does exactly what it's supposed to practice: adapt a iii-pin XLR signal to a 4-pivot TRRS betoken.
It's critical to annotation that this adapter cable does not pass power (DC bias or phantom), so it will not work with active microphones (remember condensers). Therefore, information technology's imperative that we employ passive (call up dynamic) mics with this adapter.
For an XLR-TRRS adapter with a phantom power supply option, check out the Saramonic Smartrig Ii XLR (link to check the price on Amazon). With this relatively inexpensive adapter, we tin supply our active microphones with the full +48V phantom power. This is possible with just 1 9V battery.
XLR-TRRS Adapter Cable With Phantom Power
For everything you need to know nigh headphone jacks, check out my in-depth commodity How Do Headphone Jacks And Plugs Work? (+ Wiring Diagrams).
Connecting An External Microphone To A Smartphone Wirelessly Via TRRS Headphone Jack
Information technology'southward also possible to connect a wireless external microphone to a computer without Bluetooth, then long as the wireless receiver tin make the proper physical connection with the phone's headphone jack (or charger port, which we'll hash out presently).
Wireless microphone systems, including the aforementioned Bluetooth systems, apply radio waves to transmit audio information wirelessly.
A microphone transmitter embeds the microphone audio into a radio point at a specified frequency (VHF or UHF). The transmitter then sends the radio wave wirelessly for the receiver to option upwards. In one case received, the receiver decodes the radio signal, taking the audio point and outputting it.
For a detailed read on the inner workings of wireless microphone systems, check out my article How Practise Wireless Microphones Work?
So as long as the receiver tin can plug into the smartphone via the TRRS headphone jack, we tin finer connect any microphone to a smartphone.
Wireless Microphone Systems With TRRS Connections
Let'due south take a look at a pop example of a wireless mic system with a TRRS connector:
Wireless mic organization with TRRS example: Movo WMIC50 (link to cheque the cost at Movo Photo).
With TRRS Phone Connection
The Movo WMIC50 arrangement comes with a wireless transmitter and receiver that work on the popular 2.4GHz radio frequency band. On tiptop of the headphones, this pack comes with a lavalier mic and a TRRS connector to connect the receiver to the smartphone.
Annotation that the lav mic also has a TRRS connector and may be connected direct to the smartphone if that'southward preferred!
XLR-Wireless Transmitter
Note that whatsoever professional wireless mic system could connect to a smartphone if the receiver's output signal can be adapted to connect to the smartphone jack.
See the XLR-TRRS adapter options listed above or the XLR-USBC or XLR-Lightning adapters listed below.
Connecting An External Microphone To A Smartphone Via Charging Port
Lastly, some microphones can connect to a smartphone via the charging port of the smartphone.
USB microphones take become very common for their ease of use with computers. Smartphone "charger port" microphones work in similar ways.
For more than information on USB and digital microphones, check out the following My New Microphone manufactures:
• How To Connect A Microphone To A Estimator (A Detailed Guide)
• Do Microphones Need Drivers To Work Properly With Computers?
• Are Microphones Analog Or Digital Devices? (Mic Output Designs)
To properly connect to a smartphone's charging port, the microphone'due south bespeak must exist converted to digital audio. This is done via an ADC betwixt the mic capsule and the charger port connector.
Let'south look at some microphone examples:
USB-C And Lightning Connection Microphones
The 2 most mutual smartphone charger ports are the USB-C (Android and others) and the Lightning (Apple). At that place are digital microphones on the marketplace that connect to both.
An example is the Boya Past-DM2 (link to check the price on Amazon).
With USB-C Connectedness
The Boya Past-DM2 is a lavalier mic that connects straight to a smartphone via USB-C (Android and others).
The By-DM2 has an ADC built within the cablevision (the relatively large box between the mic and the connector).
Some other example: Shure MV5 (link to bank check the price on Amazon).
With USB-C & Lightning Cable Adapter
The Shure MV5 is more flexible with its ADC built into the mic body and its female person micro-USB output. In the case of the MV5, whatsoever male micro-USB to male (insert charger port type here) volition effectively connect the mic to your smartphone (or another digital device).
The Shure MV5 comes with both a micro-USB to Lightning and a micro-USB to USB cablevision, though micro-USB to USB-C adapters are available on the market place (link to Amazon).
Shure is featured in the following My New Microphone articles:

• Top thirteen Best Headphone Brands In The Earth
• Summit 14 Best Earphone/Earbud Brands In The World
As mentioned earlier, it's sometimes desirable to connect our XLR microphones to our smartphones. We tin can connect XLR mics to our smartphone charger ports with the following adapters:
XLR-USBC Adapter
Saramonic UTC-XLR (link to bank check the price on Amazon).
A unproblematic XLR to USB-C adapter with a congenital-in analog-to-digital converter. Note that this cablevision does not provide or pass phantom power.
XLR-Lightning Adapter
Saramonic LC-XLR (link to check the price on Amazon).
A simple XLR to Lightning adapter with a congenital-in analog-to-digital converter. Annotation that this cable does not provide or pass phantom power.
Phantom Power Supply
If you desire to use your agile condenser mics (that require phantom power) with the in a higher place adapters, you'll need to power them properly. This is where in-line phantom power supplies come up into play.
Although I don't typically recommend Neewer products, their in-line phantom power supplies do piece of work well:
Neewer 1-Channel Phantom Power Supply (link to check the cost on Amazon).
This simple 1-channel phantom power supply will effectively power your condenser microphones if they need the +48V.
Connect your XLR to the PS input and your XLR-charger port adapter to the PS output, connecting the adapted end of the cable to your smartphone.
Note that these power supplies are relatively bulky and require external powering to function.
Neewer 1-Channel Phantom Ability Supply – USB Powered (link to bank check the price on Amazon).
(USB Powered)
This phantom PS works the same as the i above, except it is powered via USB rather than from a wall plug.
Note that the USB acts simply to power the PS and that this device is not a digital audio interface! The USB does non send any digital sound.
To larn more than about phantom power, cheque out my commodity What Is Phantom Power And How Does It Work With Microphones?
Smartphone Audio Software For External Microphones
In general, a smartphone will automatically switch its audio input over to a plugged-in microphone when a connection is made (just similar it switches from its born speakers to headphones once those headphones are plugged in).
Once this connection is fabricated, the external microphone can be used with whatsoever sound recording software and as the principal microphone of the smartphone.
Recap On Connecting External Mics To Smartphones
So we've gone through many methods of connecting external microphones to smartphones. Some of these methods are clean and simple, while others are complicated and require in-line devices and adapters.
Let's chop-chop epitomize the methods provided in this article, dividing them up by microphone type:
Bluetooth Microphones
Turn the Bluetooth microphone transmitter on and pair the devices within the smartphone settings.
1/8″ TRRS Microphones
Assuming the microphone follows the CTIA standard, connect the male TRRS microphone connector into the headphone port of the microphone.
1/8″ TRRS Wireless Microphones
If the receiver of a wireless mic organization has a 1/8″ TRRS (CTIA) connection, set up the wireless system properly and connect the receiver directly to the smartphone.
USB-C And Lightning Connexion Microphones
For these microphones, plug the compatible connector into the smartphone'due south charger port.
XLR (And Other Connexion Type Microphones)
There are enough of methods to connect XLR microphones to smartphones.
Ensure yous accept the proper adapters and, if needed, the proper power supplies and/or analog-to-digital converters.
Tin y'all use a microphone in a headphone jack? Headphone jacks are wired to output signals by default, then microphones typically do not work with them. However, some microphones (like external smartphone mics) are wired to properly input signals through a headphone jack. So yes, in some cases, mics can be used with headphone jacks.
For more data on headphone jacks, check out the following My New Microphone articles:
• How Do Headphone Jacks And Plugs Piece of work? (+ Wiring Diagrams)
• Are AUX (Auxiliary) Connectors & Headphone Jacks The Aforementioned?
• Differences Betwixt ii.5mm, 3.5mm & half dozen.35mm Headphone Jacks
Where is the microphone in a smartphone? Smartphones typically have several built-in microphones. They are more often than not found at the ends of the smartphone (near the meridian and lesser) though they may be found elsewhere.
