Headphone mode on Xiaomi: why turn on itself and how to turn it off forever

You plugged your headphones into a Xiaomi smartphone, but you forgot to disconnect them — and the sound still only goes through the headset speaker, even though it's long gone — or the phone suddenly decided that the headphones are connected even though you haven't even used them? This problem is familiar to many owners of Redmi, POCO and Mi devices — the headphone mode can activate spontaneously due to software failure, contamination of the connector or hardware malfunctions.

In this article, we will look at all the possible reasons for automatically turning on the headphone mode and offer 5 working ways to turn it off, from a simple reboot to a deep reset. You will also learn how to prevent a problem from recurring and what to do if none of the methods worked. The instructions are suitable for all current Xiaomi models, including the Redmi Note 12, POCO X5, Mi 11 and older devices on MIUI 12/13/14.

Why does Xiaomi itself include headphone mode?

There are several reasons for sudden activation of the headphone mode, most often due to hardware malfunctions or software failures.

• 🔌 3.5mm jack contamination or oxidation – dust, moisture or corrosion can create false contact, causing the system to “think” that the headphones are connected.
• 🤖 Failure to work MIUI — Firmware errors, especially after an update, sometimes lead to improper processing of signals from the audio jack.
• 🔧 Damage to the audio chip – physical failure of the chip responsible for recognizing connected devices.
• 📱 Application conflict – some programs (such as players or messengers) can force audio output to switch.
• 🔄 Incorrect audio settings – manually exposed settings (such as forced output via Bluetooth) sometimes get confused.

If the headphone mode is turned on only when you connect the charging, the problem is most likely to be the closure of the contacts due to wear of the connector. If the smartphone “gluts” even without connecting cables, the software or hardware breakdown is to blame.

Method 1: Rebooting your smartphone is the easiest method

In 60 percent of cases, the headphone mode is turned off after a normal reboot, which is because MIUI temporarily forgets about the false headset connection.

1. Press the power button for 2-3 seconds.
2. In the menu that appears, select Reboot (or Restart).
3. Wait for the smartphone to be turned off completely (usually takes 30–60 seconds).

If after the reboot the sound still goes "in the headphones", try the forced reboot:

• Press the buttons Power + Volume increase for 10-15 seconds.
• Let go when the Xiaomi logo appears on the screen.

💡

If your smartphone doesn’t respond to buttons, plug it into charging for 5-10 minutes — sometimes it helps to wake up the system.

Method 2: Cleaning the 3.5mm connector (if any)

If your Xiaomi model is equipped with a headphone jack (Redmi 9A, POCO M3, etc.), the problem may be its contamination, and dust, pile, or contact oxidation create false resistance, which the system perceives as a connected headset.

How to clean the connector:

1. Turn off your smartphone.
2. Take a toothpick (not a metal one!) or a soft brush (for example, for drawing).
3. Carefully remove visible contaminants from the connector without pressing on the contacts.
4. Use alcohol wipes to remove oxidation (do not overdo it with moisture!).
5. Let the connector dry for 10-15 minutes, then turn on the phone.

If the problem persists after cleaning, try inserting and removing the headphones 3-5 times – sometimes this resets false recognition.

Method 3: Resetting the sound settings in MIUI

Incorrect audio settings can make a smartphone “think” that the headphones are connected, to reset them:

1. Go to Settings. → Sound and vibration.
2. Slip on Additional settings (or Advanced sound settings).
3. Select Reset Sound Settings (in some versions of MIUI, this option may be called Reset Default Settings).
4. Confirm the action.

After reset, check if Forced Output is enabled through headphones in the settings of specific applications (for example, in YouTube or Spotify).

Turn off Bluetooth headphones in the Quick Settings menu | Check the output in the player (for example, in Google Music) | Make sure that the headset mode is not activated in the call settings |Reboot the smartphone after resetting

Method 4: Update or roll back the MIUI firmware

If the headphone mode started to turn on after the system update, the problem may be a firmware bug.

• 📥 Update to the latest version MIUI (if available).
• 🔙 Recoil on the previous stable version (if the bug appeared after the update).

How to update firmware:

1. Open Settings → About the phone → Update MIUI.
2. Click Check for updates.
3. If a new version is available, download and install it.

To roll back the firmware will require an unlocked bootloader and custom recovery (such as TWRP), which is only suitable for advanced users!

💡

If the problem has occurred after the update, check the firmware reviews on forums (like 4PDA or Xiaomi Community) – it may be a massive bug and the fix has already come out.

Method 5: Hard reset (if nothing worked)

If all previous methods fail, you will have a complete reset, which will delete all data from the device, so back up first!

How to reset Xiaomi to factory settings:

1. Open Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Enter a password (if required) and confirm the action.
4. Wait for the process to be completed (it will take 5-10 minutes).

⚠️ Attention! After a hard reset, all photos, contacts and apps will be deleted, and if you don't sync with Mi Account, you can't recover the data.

If even after reset, the headphone mode continues to turn on, the problem is 100% hardware - you need to repair the audio chip or replace the connector in the service center.

What if none of the methods worked?

If you’ve tried all the instructions, but the smartphone still “sees” non-existent headphones, there are two options:

• 🔧 Contact the service center - the master will check the integrity of the audio chip and connector contacts. ₽.
• 📱 Use Bluetooth headphones – if the hardware breakage is uncritical, you can temporarily switch to a wireless headset.

Important: If the headphone mode only turns on when charging is connected, never use fast charging – this can aggravate the closure of contacts and cause the USB-C port to fail.

⚠️ Don’t try to disassemble the smartphone yourself – modern Xiaomi models have fragile plumes, and careless intervention can lead to breakage of the display or motherboard.
