How to turn off headphones on Xiaomi Redmi 6: if the sound goes only to the headset

Xiaomi Redmi 6 is a reliable budget smartphone, but even it sometimes has strange sounds. One of the most common problems is that the phone freezes in headphone mode, even when they have long been removed from the connector, the speaker is silent, and the icon of the headset still burns in the status bar. Why does this happen and how does it get back to the sound?

The cause is usually a contaminated 3.5 mm connector, software failure, or mechanical damage to the contacts, and 80 percent of the time, you can solve the problem yourself without going to the service center, and we've put together all the working methods, from the simplest to the most radical, with an explanation of when to use them.

Important: If the sound has not recovered after all the manipulations, this may indicate a hardware malfunction, such as damage to the audio chip or oxidation of contacts on the board, in which case a diagnosis will be required in the service.

Why Xiaomi Redmi 6 does not switch from headphones to speakers

The smartphone detects the headphones by closing the contacts in the 3.5 mm jack. When the headset is inserted, the internal contacts connect, and the system understands that the sound should be directed to the headphones. If the contacts remain closed after extraction (due to dirt, moisture or deformation), the phone continues to “think” that the headphones are connected.

The main causes of the problem:

• 🧹 Connector contamination – dust, pile, or debris block contacts, simulating the headset connection.
• 💧 Moisture intake – oxidation of contacts after condensation or rain.
• 🔄 Software failure - an error in the operation of the audio driver or MIUI.
• 🔌 Mechanical damage – a bent headphone plug or a connector on the phone.
• 🛠️ Audio chip malfunctions are rare but require repairs.

Before you try radical methods (like resetting), start by mechanically cleaning the connector, which helps in 60% of cases. If the problem occurred after the MIUI update, the software is to blame, and rebooting or rolling back the updates will help.

Method 1: Mechanical cleaning of the 3.5 mm connector

The simplest and most effective method is to clean the connector from dust and debris, and it doesn't require special tools, it takes a toothpick and a flashlight.

Toothpick or plastic spatula

Lantern (on another phone)

Alcohol wipes or cotton swab soaked in alcohol

Magnifying glass (optional)

Step-by-step:

1. Turn off the Xiaomi Redmi 6 to avoid short circuit.
2. Illuminate the connector with a flashlight - look for foreign objects (pillow, dust, oxidation).
3. Carefully walk the toothpick through the internal contacts without pressing hard.
4. Moisten the cotton swab in alcohol and wipe the contacts to remove fat or oxides.
5. Let the connector dry for 5-10 minutes, then turn on the phone.

If the sound has not recovered after cleaning, try inserting and removing the headphones several times - sometimes this helps to "wake up" contacts. Do not use metal objects (needles, paper clips) - they can damage the contacts or close them.

💡

If there is no alcohol at hand, you can use a pencil eraser - it removes oxides from metal contacts well.

Method 2: Forced disabling of headphones through the engineering menu

If mechanical cleaning didn't work, try resetting the audio settings through a hidden engineering menu, which works even if the connector is physically fit, but the system misidentifies the headset's connection.

Instructions for Xiaomi Redmi 6:

1. Open the phone app and dial the combination: ##36446337###
2. The Engineering Mode menu will open (if it doesn't open, try another code: ##4636###).
3. Go to Hardware Testing → Audio → Headset Mode.
4. Press Headset Switch and select Disabled.
5. Reboot the phone.

After the reboot, check if the headphone icon has disappeared in the status bar. If the menu does not open or if the Headset Mode option does not open, then your version of MIUI does not support it - move to the next method.

Method 3: Resetting sound settings via Safe Mode

If the problem is caused by an application conflict (for example, after installing Equalizer or Viper4Android), it will help to download in safe mode.

How to run Safe Mode on Xiaomi Redmi 6:

1. Press the power button until the shutdown menu appears.
2. Press and hold the "Switch off" (or "Switch off" power) option until a request to go to Safe Mode appears.
3. Confirm the action - the phone will restart.

In Safe Mode, check if the sound is working through the speaker. If so, a problem in one of the installed applications, remove the recently installed programs (especially those related to sound) and restart the phone as normal.

⚠️ Warning: Safe Mode disabled all third-party apps, including Google Play.To exit Safe Mode, just restart your phone.

Method 4: Update or roll back the MIUI firmware

Sometimes a bug with "hang" headphones appears after the MIUI update. If the problem began after the update, try:

• 🔄 Reverse to the previous version (if there is a backup).
• 📥 Update to the latest stable firmware (maybe the bug has already been fixed).
• 🧪 Install custom Recovery (for example, TWRP) and sew clean MIUI.

How to check the MIUI version:

1. Open the Settings. → The phone.
2. See the line MIUI version (e.g. MIUI Global 12.5.4).
3. Compare the latest stable versions on Xiaomi’s official website.

If you're not sure about your firmware skills, you better go to the service. The wrong update can turn your phone into a brick.

Method 5: Hardware reset (if nothing helps)

If all previous methods fail, you have a complete reset, which will delete all data from your phone, so back up first.

How to reset Xiaomi Redmi 6 to factory settings:

1. Open Settings → Additional → Recovery and Reset.
2. Select Settings Reset.
3. Confirm the action and wait for the reboot.

Once reset, the phone will turn on as new, check if the headphone problem has gone away, and if it hasn't, it's probably a hardware malfunction and needs repair.

⚠️ Note: Resetting will not help if the cause is physical damage to the connector or audio chip. in this case, contact the service center Xiaomi - self-repair can aggravate the problem.

💡

Before resetting, be sure to transfer photos, contacts and messages to your computer or the cloud. After resetting, data will not be recovered!

Frequent Mistakes and How to Avoid Them

Many users make the problem worse with the wrong actions. Here's what you can't do if the Xiaomi Redmi 6 doesn't turn off the headphones:

• 🔨 Picking the connector with metal objects – this can close the contacts or scratch them.
• 💦 Water the connector with water or alcohol - the liquid should be applied only to the cotton swab.
• 🔥 Heating the phone with a hairdryer is dangerous for the battery and board.
• 📱 Install unofficial firmware without backup - the risk of getting a "brick».

If you are not sure of your actions, it is better to consult a specialist. For example, replacing a 3.5 mm connector in the service is inexpensive (from 500 rubles), but requires soldering work.

Another common myth is that if you blow into the connector, the dust will fly out. In fact, it only drives the garbage deeper inside. Use dry brushing with a toothpick or compressed air (a canister to clean the equipment).
