How to Use Your iPhone as a Microphone for PC (2 Methods That Actually Work)

Your iPhone already holds one of the better microphones you own, and with the right app, Windows will recognize it as a fully functional audio input device. This guide covers the two setups that actually work. The WO Mic over Wi-Fi and the WO Mic over USB. Each method takes under ten minutes to configure, and you do not need to buy anything to get started.

What You Need Before You Start?

Before choosing a method, confirm you have everything in place:

• iPhone running iOS 14 or later

• Windows PC running Windows 10 or Windows 11

• Same Wi-Fi network for both devices (required for all wireless methods)

• Lightning-to-USB or USB-C cable (required for USB mode; useful as a fallback for Wi-Fi mode)

• WO Mic app from the App Store. The WO Mic PC client and driver from the WO Mic website

• Administrator access on your PC for driver installation

This guide covers Windows PCs only. macOS setup paths differ and are not included here.

Comparing Your Options at a Glance

Use this table to pick the right method before reading through the full steps.

WO Mic (Best All-Round Option)

WO Mic is the most widely used solution for this task. It installs a virtual audio driver on your PC, which makes Windows treat the iPhone as a standard input device. Both Wi-Fi and USB modes run from the same app, so you install once and can switch between them at any time.

Install the WO Mic App and PC Client

Both installations must be completed before working on any methods. The USB driver in particular is mandatory even if you plan to connect wirelessly.

1. On your iPhone, open the App Store, search for WO Mic, and install the free app.

2. On your PC, visit the WO Mic website (wolicheng.com) and download the WO Mic PC client.

3. Run the installer. When the wizard reaches the driver step, install the WO Mic device driver — this is a separate prompt inside the installer and should not be skipped.

4. Restart your PC if prompted.

5. Once restarted, open the WO Mic PC client. You will see a connection window listing available transport options.

Method 1: Connect via Wi-Fi

1. Confirm your iPhone and PC are connected to the same Wi-Fi network (and the same band on a dual-band router).

2. Open the WO Mic app on your iPhone and tap the settings gear.

3. Set Transport to Wi-Fi, then tap Start.

4. Note the IP address displayed on the iPhone screen.

5. In the WO Mic PC client, go to Connection > Connect.

6. Select Wi-Fi as the transport type and enter the IP address from your iPhone.

7. Click Connect. The status indicator in both the app and the PC client should turn green within a few seconds.

Once connected, the iPhone microphone feed is live. Move to the Windows audio configuration section below to make it the active input.

Method 2: Connect via USB (Lower Latency)

USB mode routes audio through the cable rather than the network, eliminating Wi-Fi-introduced delay. This is the preferred mode for recording sessions, gaming voice chat, or any call where you notice lag.

1. Plug your iPhone into your PC using a Lightning-to-USB or USB-C cable.

2. On the iPhone screen, tap Trust when the “Trust This Computer?” prompt appears.

3. Open the WO Mic app, tap the settings gear, and set Transport to USB.

4. Tap Start.

5. In the WO Mic PC client, go to Connection > Connect, select USB, and click Connect.

6. Status indicators on both the app and the client should turn green.

Note: If the PC client does not detect the iPhone over USB, the most common cause is a missing or outdated driver. Re-run the WO Mic installer and choose “Repair” to reinstall it, then reconnect the cable.

Set Your iPhone as the Default Microphone in Windows

This step is required after completing the app-layer connection for either method above. Windows does not automatically switch its active audio input when a new device connects, so you must set it manually.

Option 1:

1. Open Settings and navigate to System > Sound.

2. Under Input, click the Choose your input device dropdown.

3. Select Microphone (WO Mic Device).

4. Click the device entry and use the Test your microphone bar to confirm the signal is registering when you speak.

Option 2:

1. Open Control Panel > Sound.

2. Click the Recording tab.

3. Right-click the iPhone input device and select Set as Default Device.

4. Right-click it again and select Set as Default Communication Device.

5. Speak into your iPhone and watch the level meter in the Recording tab to verify audio is being received.

Note: Some applications manage audio routing independently of Windows system settings. If you use Discord, OBS, or Zoom, open that app’s own audio settings and select the WO Mic directly. In Discord, for example, go to User Settings > Voice and Video > Input Device and choose the correct device from the dropdown.

Troubleshooting — iPhone Not Showing Up as a PC Microphone

PC Doesn’t Detect the iPhone

• Wi-Fi mode, device not found: Confirm both devices are on the same network and the same band. Dual-band routers can place a phone on 2.4 GHz and a PC on 5 GHz, breaking the local connection.

• IP address mismatch: Reopen the WO Mic app and verify the current IP address; it changes after every new Wi-Fi connection.

• USB mode, iPhone not recognized: Reinstall the WO Mic USB driver using the installer’s Repair option. Try a different USB port. Disconnect and reconnect the cable to trigger the “Trust This Computer?” prompt again if you missed it the first time.

• App not running on iPhone: The WO Mic app must be open and actively running on the iPhone before the PC client attempts to connect. Make sure the iPhone screen has not locked and put the app in the background.

Audio Delay or Latency

Wi-Fi mode typically introduces 50 to 200ms of delay. For Zoom or Teams calls, most users find this tolerable. For live streaming, the drift between audio and video becomes noticeable and will frustrate viewers.

The most effective fix is switching to USB mode. If running a cable is not practical, open the WO Mic PC client, navigate to Settings, and reduce the Buffer Size value. A smaller buffer lowers delay at a slight cost to dropout resistance on a congested network.

• Bluetooth audio routing carries 150–300ms or more of delay in most configurations. It is not a reliable method for any latency-sensitive use case and is not recommended here.

Poor Audio Quality or Low Volume

1. In the WO Mic PC client, go to Format settings, set the Sampling Rate to 44100 Hz, and switch to Stereo if the current mode is mono and volume sounds thin.

2. In Windows Sound Settings, go to Recording > your iPhone input device > Properties > Levels and raise the microphone volume to 80 or higher.

3. Position your iPhone within one meter of your mouth. Avoid pointing the microphone toward a hard, reflective surface such as a monitor or bare desk, as these create noticeable echo and room reverb.

When It’s Worth Getting a Dedicated Wireless Mic Instead

If you have already tried the methods above and still face issues, hardware may help. Wi-Fi dropouts can still happen often. You might also deal with the driver reinstalling each session. Audio quality may still feel low for regular content work.

A hardware option removes all routing steps at once. The Hollyland LARK A1 can be considered here. Its USB-C receiver also has a Lightning version. It connects directly to your PC. The system is detected instantly as an audio input. No app or driver is needed. It also does not rely on any network connection.

The clip-on transmitter goes on your collar. It includes three-level smart noise cancellation. It can give a cleaner sound than iPhone routing methods.

FAQs

Is WO Mic free?

Yes. WO Mic’s free tier is fully functional for audio routing but displays advertisements in the mobile app. The paid upgrade removes those ads and unlocks premium audio configuration options.

Does this work for Discord and gaming?

Yes. Once your iPhone registers as an active Windows audio input, any application that reads from Windows Sound settings picks it up automatically. This includes Discord, Steam Voice Chat, and TeamSpeak. If Discord does not detect it, go to User Settings > Voice and Video and manually select the WO Mic (or Mic Device) as the input source.

Will there be noticeable audio delay on video calls?

Wi-Fi mode introduces roughly 50 to 200ms of delay, which is usually tolerable on Zoom or Teams and most participants will not notice. For live streaming, where audio must stay in sync with video output, USB mode is strongly recommended because its latency is near-zero and consistent.

Does this work on Mac?

WO Mic does not offer a native macOS client. Its desktop software officially works only on Windows and Linux.

Can I use my iPhone mic without installing any software?

Not reliably on Windows. Unlike certain macOS configurations that recognize a connected iPhone as an audio input natively, Windows requires either a driver or a third-party app bridge to surface the iPhone as an input device. There is no built-in Windows option that achieves this without additional software installed.

Conclusion

For most users, WO Mic USB is the fastest path to a working setup with the least troubleshooting. Switch to WO Mic Wi-Fi when you want to work cable-free and can accept minor latency. If hardware is a better fit for your workflow, visit the Hollyland LARK A1 for a plug-and-play alternative.
