Why Xiaomi doesn’t see headphones as a headset and how to fix it

You connected your headphones to a Xiaomi smartphone, but instead of the usual headset mode (with a microphone), the phone defines them as ordinary audio devices — without the ability to answer calls or use voice assistants? This problem occurs on models from Redmi Note 10 to Xiaomi 13 Ultra, and its causes can be due to hardware malfunctions and software failures.

80% of cases are due to a contaminated 3.5mm connector or incorrect Bluetooth settings (for wireless headphones); less often, a damaged cable, outdated firmware or application conflict. In this article, we will examine all possible causes and solutions, including hidden MIUI settings that the manufacturer does not advertise.

1. Check of the 3.5 mm connector and headphone cable

If your Xiaomi is equipped with a classic audio jack, the first step is to inspect it for oxidation, dirt or mechanical damage. Even microscopic dust particles can disrupt contact with the microphone plug (the fourth ring on the TRRS connector).

How to check:

• 🔍 Visual inspection: illuminate the connector with a flashlight - there should be no foreign objects or corrosion inside.
• 🧹 Cleaning: Use wood toothpicks (not metal!) or compressed air to remove dust. oxidized contacts will be fine with alcohol 90%+ and cotton swab.
• 🔄 Test with other headphones: if the problem persists, it's the smartphone connector. If it disappears, the cable or headphone plug malfunctions.

⚠️ Warning: Do not use sharp metal objects to clean the connector, this may damage the contacts. If the problem remains after cleaning, you may need to replace the audio chip (at the service center).

For wireless headphones (AirDots, Buds, etc.) check:

• 🔋 Battery charge: discharged headphones can only connect in playback mode, without a microphone.
• 📱 Pair: Remove the device from the list of Bluetooth devices and connect again.

2. Sound and headset settings in MIUI

MIUI has hidden parameters that affect the recognition of the headset, and often the problem is solved by resetting the sound settings or turning on a special mode.

Instructions for MIUI 12-14:

1. Go to Settings → Sound and vibration → Sound settings.
2. Find the Connected Device Type (or Headset Mode on older versions).
3. Choose a headset with a microphone (if available).
4. If there is no item, tap the icon. ⚙️ next to the volume slider and select Reset settings.

For models with Android 11+ and MIUI 13+, you may need to activate the hidden developer mode:

Tap 7 times on the MIUI version in Settings → About phone |

Return to Settings → Additional → For Developers |

Find Debugging over USB and Turn off absolute volume (turn on both) |Reboot your phone-->

⚠️ Note: On some firmware (Xiaomi.eu, customized) ROM) The type of connected device may not be available, in which case only resetting or flashing will help.

3. Reset Bluetooth and Network settings

If a problem occurs with wireless headphones, conflicts in the Bluetooth stack cache or incorrect device profiles may be to blame, resetting the settings will return everything to factory parameters.

How to reset Bluetooth:

1. Open Settings → Connections and Sharing → Bluetooth.
2. Tap it on. ⚙️ next to the connected headphones and select Forget the device.
3. Return to the main Bluetooth menu and click Reset Settings (or Clear Cache on some models).

To completely reset the network parameters (if the problem persists):

1. Settings → SIM-maps and mobile networks → Resetting network settings.
2. Confirm the action and restart the phone.

4. Update firmware and fix MIUI bugs

The manufacturer regularly releases patches to fix bugs with sound. If your Xiaomi is running an outdated version of MIUI, chances are that the problem has already been solved in new builds.

How to update firmware:

1. Go to Settings → About the phone → System update.
2. Click Check Updates and wait for the latest version to download.
3. If the update is not available, check the firmware region (should match your model).

For models with a locked booter (for example, Redmi Note 11 for Russia), you may need to manually install the update via Recovery:

⚠️ Note: Installing firmware for another region (e.g. Global instead of Russia) may lead to loss of functionality (lack of Russian, problems with the Russian language). 4G). Always check for compatibility!

5. Cleaning the cache and data of system applications

Headset failures are often caused by a damaged cache of the system services responsible for sound and connection of devices. Clearing the cache will not delete your data, but can restore the microphone to work.

Which applications need to be cleaned:

• 🎵 MIUI Sound Recorder (sound recording)
• 📞 com.android.bluetooth (Bluetooth stack)
• 🔊 com.android.server.telecom (telecom services)

Instructions:

1. Open Settings → Applications → Application Management.
2. In the search, type the name of the application (e.g. bluetooth).
3. Select Warehouse → Clear cache (not data!).
4. Reboot the phone.

💡

If after cleaning the cache, the headphones still do not work as a headset, try turning off battery optimization for the Bluetooth app in Settings → Battery → Battery Optimization

Hardware malfunctions and service repairs

If none of the software methods worked, the problem may be a physical breakdown:

• 🔌 Damaged 3.5mm connector: a common problem after falls or moisture.
• 🎛️ Faulty audio chip: Xiaomi often fails the chip Qualcomm WCD9340/9341 (responsible for sound processing).
• 🔋 Bluetooth antenna problems: relevant for models with metal body (Mi 9, Mi 10).

How to diagnose a hardware malfunction:

• Connect the headphones to another device – if they work like a headset, the problem is with the phone.
• Check if the microphone is detected in Settings → About phone → Diagnostics → Equipment test (if there is such a item).
• See if the phone is responding to the headphone connection (whether the icon appears in the status bar).

The cost of repairs in Xiaomi service centers:

💡

If the phone is warranty, do not disassemble it yourself - this will void warranty obligations.

7.Alternative solutions: USB-C and adapters

If the 3.5mm connector fails and repair is impractical, consider alternatives:

• 🔌 USB-C Headphones: modern Xiaomi models (starting with the Mi 10) support the headset through USB Type-C: Examples: Xiaomi Type-C Earphones 1More Piston Fit.
• 🔄 3.5 mm adapters → USB-C: The official adapter from Xiaomi is ~500₽ It supports the microphone.
• 📶 Bluetooth transmitters: devices like Xiaomi Bluetooth Audio Receiver allow wired headphones to be connected over the air.

When using adapters, consider:

• Not all cheap adapters support a microphone – look for models with a CS43130 or AK4490 chip.
• In some firmware MIUI You need to manually enable support. USB-audio in the settings for developers.
