How to remove headphone mode on Xiaomi, if they are not connected

Why Xiaomi is “stuck” in headphone mode and how to fix it

Did you put your headphones in Xiaomi and the sound disappeared from the speakers? Or did your phone insist that the headset is connected even though it's long gone? This is a classic problem for Redmi, POCO and Mi smartphone owners, the so-called "earphone mode bug," and there are many reasons, from a 3.5mm jack clogged to a MIUI firmware failure.

Most often, the error occurs after a physical damage to the connector (for example, if the headphones are pulled sharply), a system update or even a banal dust hit. In some cases, the phone stops “seeing” the headset shutdown and continues to direct all the sound to non-existent headphones, especially vulnerable models with a 3.5 mm connector — Redmi Note 8/9/10, POCO X3 and old flagships Mi 8/9.

In this article, we will discuss 5 working ways to turn off headphone mode on Xiaomi – from simple (reboot) to radical (reset settings).

Method 1: Rebooting your smartphone is the first step to solving

The most obvious, but often ignored, method is the banal reboot, which helps to reset the temporary failure of the audio system in 70% of cases, because MIUI sometimes forgets to send a signal about the break of connection with the headphones, and restarting the system forcedly zeroes all current states.

How to Reboot Xiaomi if the screen or buttons are not working:

• 🔄 Soft reboot: Press the power button for 10-15 seconds until the menu appears, then select Reboot».
• 🔋 Hard reset (if the phone freezes): pinch the power + Volume up for 20 seconds – the device will be forced to turn off.
• 📱 Through Recovery: if the smartphone does not respond, pinch the power + Volume up before the Mi logo appears, then select Reboot.

⚠️ Attention: If after the reboot, the speaker sound didn't appear, but the status bar still shows the headphone icon, the problem is deeper. Don't try to re-insert the headphones, this can aggravate damage to the connector.

Method 2: Cleaning the 3.5mm connector - when dust is to blame

One of the most common causes of headphone sticking is a dirty audio jack, and dust, pocket pile, or contact oxidation can create a false sense of connected devices, especially for Redmi 4X, Mi A1, and others with open connectors without protection.

How to clean the connector yourself:

1. Turn off your phone to avoid short circuits.
2. Take a toothpick (not metal!) or a wooden stick, wrap its tip with cotton soaked in alcohol (not vodka!).
3. Carefully scroll inside the connector, removing dirt. Don't push hard - the contacts are fragile!
4. Dry the connector for 10-15 minutes (you can dryer at minimum power).

Use metal objects (needles, paper clips)

Blow the connector with the mouth (saliva contains acids)

Use acetone or solvents

Insert headphones until completely drying-->

If you've had a problem after cleaning, try inserting your headphones and gently spinning the plug in the connector, which sometimes helps to wake up the contacts, but if the sound only appears when the plug is in a certain position, it's a sign of mechanical damage to the connector.

Method 3: Resetting the sound settings in MIUI

If the reboot and cleaning didn't work, the next step is to reset the audio settings to factory settings. MIUI has a separate audio section that can be reset without losing personal data.

Instructions:

1. Open the Settings. → Sound and vibration.
2. Tap three points (⋮) → Resetting the sound settings.
3. Confirm action. The phone will reboot automatically.

⚠️ Warning: After resetting the audio settings, individual equalizer settings, volume levels for different profiles and custom alarm melodies may be dropped.

💡

If your version of MIUI doesn't have "Reset Sound Settings," try disabling Audio Effects in the same section, sometimes helping to bring sound back to the speakers.

Method 4: Disable the headphone mode through the engineering menu

For advanced users, there is a way to trick the system through an engineering menu (Engineer Mode), which works if the problem is caused by a malfunction in the software part of the audio controller.

Instructions:

1. Open the Phone app and type the combination: ##36446337## (some models may not work – see alternatives below).
2. Select Hardware Testing → Audio → Headset Mode.
3. In the Headset Switch section, set the value 0 (this disables headphone mode).
4. Save the settings and restart the phone.

Alternative codes for different Xiaomi models:

• 📱 ##4636## → Audio → Headset (Universal, but not on all firmware).
• 🔧 ##284## → Audio Test (for Redmi Note) 8/9).
• ⚙️ ##283## → Loopback Test (loop check, can help reset condition).

Method 5: Hardware malfunctions - when you need to carry to the service

If all software methods have been tried, but the phone still thinks the headphones are connected, the problem is almost certainly hardware.

• 🔌 Damage to the 3.5 mm connector: oxidation, bent contacts or break of tracks on the board.
• 💧 Fluid intake: Even a small amount of moisture can cause corrosion.
• 🔧 Failure of the audio codec (chip responsible for sound processing).
• 🔋 Problems with the plume (relevant for models with removable battery, for example, Redmi) 3S).

How to diagnose a hardware malfunction:

1. If you have a sound, but the phone doesn't see it, the problem is the connector.
2. Try connecting your headphones via Bluetooth, and if the sound is normal, the 3.5mm port is faulty.
3. Light a flashlight into the connector: if you see foreign objects, oxidation or bent contacts - you need a replacement.

⚠️ Warning: don't try to disassemble the phone yourself if you don't have experience! In Xiaomi models, the audio jack is often soldered to the motherboard, and careless handling can disable other components. The average cost of replacing the connector in the service is 800-1,500 rubles.

💡

If the phone is warranty, don't open it or clean the connector with alcohol, which can cause you to refuse free repairs.

More advice: what to do if nothing helps

If all of these methods didn’t work, here are some other non-obvious solutions:

Update MIUI to the latest version:

Sometimes a bug with headphone mode is fixed in new firmware versions. Check for updates in Settings → About Phone → System Update. If an update is available, install it.

2. Use of wireless headphones:

If the sound is critical and repairs are delayed, plug in a Bluetooth headset, which will work in most cases even if the 3.5mm connector is faulty.

Temporary magnet solution (for models with built-in Hall sensor):

Some Xiaomi users have noticed that if you hold a small magnet to the top of the phone (where the proximity sensor is located), the system may “think” that the headphones have turned off.

4. Reset to factory settings:

The last measure, a full reset, should only be applied if other methods have not worked. Pre-backup the data through Settings → Additional → Backup.

💡

Before resetting, try creating a new user on the system (Settings → Users). Sometimes a bug with headphones is tied to a specific profile, and the new account sound works fine.
