How to turn off headphone mode on Xiaomi Redmi 8: all working ways

You plugged your headphones into the Xiaomi Redmi 8, but even after you remove them, the phone still thinks they're connected? The sound only goes through the headphone speaker, and the headset icon is on the status bar? This problem is familiar to many owners of budget Xiaomi smartphones, especially after MIUI upgrades or mechanical damage to the 3.5 mm connector. In 90% of cases, it can be solved independently - without visiting the service center.

In this article, we will discuss 5 proven ways to remove headphone mode on the Redmi 8, including software settings, connector cleaning and hardware reset. You will also learn why the phone freezes in this mode and how to prevent the problem from recurring. All methods are tested on current versions of MIUI 12-14 and are suitable for Redmi 8/8A/8A Pro models.

Why is Redmi 8 “stuck” in headphone mode?

The reason is almost always a hardware or software error in processing a signal from a 3.5mm connector.

• 🔌 Contamination or oxidation of contacts – dust, moisture, or corrosion interfere with the correct determination of the connected device.
• 🤖 Failure MIUI — After updating or resetting the settings, the system may misinterpret the connector state.
• 🔧 Mechanical damage – wear of the connector, bent contacts or short circuit inside the socket.
• 📱 Application conflict – some programs (such as players or modified firmware) block automatic audio switching.

Interestingly, Redmi 8 is more likely to have a problem with non-original headphones with a non-standard plug-in, and cheap headsets can trick the connector sensor into thinking that the headphones are connected even after they are removed.

Method 1: Reboot your phone (the easiest method)

In 60 percent of cases, the headphone mode is reset by a normal reboot, which is because MIUI caches the state of the audio jacks, and sometimes this cache freezes.

How to Reboot Redmi 8 Properly:

1. Press the power button for 3-5 seconds.
2. In the menu that appears, select Reboot (not “Switch off!”).
3. Wait for the phone to turn off and automatically turn on.

If after rebooting the icon of the headphones disappeared, but the sound still goes only to the earphone speaker - try inserting and removing the headset 2-3 times. Sometimes this helps to "wake up" the sensor connector.

💡

If the phone doesn't respond to the power button, press it for 10 to 15 seconds to force it to restart.

Method 2: Cleaning the 3.5mm connector (if the cause is contamination)

Dust, pile or contact oxidation are common causes of false headphones. On the Redmi 8, the 3.5mm connector is located at the bottom of the case and is often clogged with garbage from pockets.

How to clean the connector yourself:

• 🕯️ Use a toothpick with cotton wool dipped in alcohol (do not overdo it with moisture!).
• 💨 Blow the connector with compressed air (for example, a canister to clean the keyboard).
• 🔦 Light up with a flashlight - if you see bent contacts, contact the service.

After cleaning, insert and remove the headphones 3-4 times to “recalibrate” the sensor. If the problem persists, move to the next method.

Method 3: Resetting sound settings through an engineering menu

The engineering menu (#36446337##) allows you to reset the audio system settings, including processing signals from the 3.5mm connector.

Step-by-step:

1. Open the Phone app and enter the combination: ##36446337###
2. From the engineering menu, select Hardware Testing → Audio → Headset Mode.
3. Press Headset Switch and select Disable.
4. Go back to the main menu and select Audio → Normal Mode → Restore Default.
5. Reboot the phone.

⚠️ Warning: Do not change other options in the engineering menu unless you are sure of their purpose. Incorrect settings can lead to loss of sound or microphone.

Method 4: Software reset via MIUI settings

If the problem is caused by a firmware failure, resetting only the sound system (without deleting data) will help, a method safer than completely resetting to factory settings.

Instructions:

1. Go to Settings → Sound and vibration → Additional settings.
2. Select Reset Sound Settings (in some versions of MIUI, the item is called Reset Default Settings).
3. Confirm the action and wait for the process to be completed.
4. Reboot the phone.

After reset, check the jack by plugging in and out the headphones. If the headset icon is gone, but the sound is still not coming through the speakers, try changing the sound profile manually:

• Open Settings → Sound and vibration → Sound mode.
• Select Sound through the speaker (not Headphones or Bluetooth).

Method 5: Hardware reset (if nothing helps)

If all previous methods fail, you can either completely reset to factory settings or repair the connector. On Redmi 8, the hardware reset is done like this:

⚠️ Warning: This method will delete all data from the phone (photos, contacts, messages). → Additionally. → Backup and reset.

Instructions:

1. Turn off the phone.
2. Press the power + volume buttons for 10-15 seconds at the same time.
3. In the Recovery menu, select Wipe Data → Wipe All Data (manage by volume buttons, confirm by power button).
4. After reset, select Reboot → Reboot to System.

If after reset the problem remained, most likely, the 3.5 mm connector itself is defective. In this case, contact the service center - self-repair can lead to damage to the motherboard.

💡

Check your phone with a different headset before you visit the service, and sometimes the problem is with faulty headphones, not your smartphone.

Comparison of methods: which way to choose?

In the table below, we have collected all the methods, indicating their effectiveness and risks, which will help you choose the best option for your situation.

How can we prevent the problem from recurring?

To prevent the headphone mode from turning on spontaneously, follow these recommendations:

• 🛡️ Use original or certified headphones with the correct plug sling.
• 🧹 Regularly clean the connector 3.5 mm from dust (every 2-3 months).
• 🔄 Avoid sharp headphone removal – first press Stop in the player, then carefully remove the plug.
• 📱 Don't update. MIUI Beta versions – they often contain sound bugs.
• 🔋 Watch the battery level. On the Redmi 8, when the discharge is below 10%, there may be malfunctions in the audio system.

If you often plug in headphones, consider using a Bluetooth headset, which will reduce the load on the 3.5mm connector and extend its life.
