How to turn off the headset on Xiaomi Redmi Note 7: all working ways

Xiaomi Redmi Note 7 is one of the brand's most popular smartphones, but even it's not immune to headset recognition bugs. You took your headphones out of the headset, and your phone still thinks they're connected? The sound only comes through the headset speaker, even though it's long gone? Or there's a constant notification on the screen about connected headphones? This problem is familiar to many Redmi Note 7 owners -- and today we're going to look at all the ways to solve it.

The reasons for sticking can range from software failure to physical contamination of the connector. 80% of the time, the problem is solved without a service center — just a few simple steps. In this article, you will find 5 proven methods to turn off the headset, as well as tips for what to do if nothing helps. We tested the instructions on the Redmi Note 7 with MIUI 10-14 firmware, but they are also relevant for other models of the Redmi Note series (5/6/8/9).

Before you go to radical measures (like resetting), try the basic methods — they work in most cases. And if your smartphone “can’t see” the headset shutdown due to a hardware malfunction, we’ll tell you how to diagnose it.

Why the phone does not turn off the headset: the main reasons

Before you try to cheat, it’s important to understand why the Redmi Note 7 doesn’t recognize the headphones being turned off.

• 🔌 3.5mm connector contamination: Dust, pile, or contact oxidation interfere with the connection sensor's proper operation, and even microscopic particles can create a false signal about a connected headset.
• 🤖 Software failure MIUI. Xiaomi’s operating shell sometimes “forgets” to update its connection status after removing the headphones.This can happen after an update, installing third-party apps, or abruptly removing the plug.
• 🔊 The audio chip malfunctions. In rare cases, the problem lies in the hardware, for example, after a fall or moisture, then the smartphone will "see" the headset even with a clean connector.
• 📱 Application conflict: Some programs (e.g., players or instant messengers) may block the audio system from working properly, especially if they are given audio control rights.

The first two are usually the most common causes, and if your Redmi Note 7 gets stuck after you upgraded your MIUI or installed a new app, it's almost certainly software, and if the connector is externally damaged or your phone falls into the water, you might suspect a hardware malfunction.

⚠️ Attention: If after removing the headphones in the speaker of the phone hears noise or cracking, and the sound in the speakers is absent - this may indicate damage to the audio chip.

Method 1: Reboot your phone (the easiest method)

To start with, the most obvious, but often effective, solution is that a smartphone reset resets the system's temporary data, including the state of the audio subsystem, which helps 60 to 70 percent of the time when a software failure causes a problem.

How to Reboot the Redmi Note 7:

1. Press and hold the power button (it is on the right end of the case).
2. In the menu that appears, select Reboot (or Restart if you have English firmware).
3. Wait 30 to 60 seconds for the phone to turn off completely and re-energize.

After you reboot, check if the notification on the connected headset has disappeared. If so, the problem is solved! If not, move on to the next method.

💡

Rebooting is the first step in any software failure, and it doesn't delete data, but it resets temporary system errors.

If a normal reboot doesn’t work, try a hard reset:

1. Press the power button + the volume button for 10-15 seconds.


2 Release the buttons when the MI logo appears on the screen.




3. wait for the system to fully load.

⚠️ Note: Forced reboot does not delete data, but can interrupt background processes.Do not use this method during system updates or backups.

Method 2: Cleaning the 3.5mm connector from dust and debris

If the reboot didn't work, the next thing to check is the physical condition of the connector, and over time, the headphone jack gets dust, pile from your pocket or bag, and sometimes even small debris, which can create a false contact that makes the phone "think" that the headset is connected.

How to clean the connector:

• 🕯️ Use a toothpick or a wooden stick, carefully, without pressing, swipe the inner contacts of the connector to remove visible contamination.
• 💨 Blow the connector with compressed air, you can use a spray to clean the equipment or just blow a lot (but not saliva!).
• 🧲 Use a magnet (carefully!) If metal sawdust hit the connector, bring a weak magnet (such as from a refrigerator) to help remove them.
• 🔦 Check with the backlight. Take a flashlight and shine it into the connector, and you'll see if there's any debris left inside.

Do not use metal objects (needles, pins, knives) to clean - they can damage the contacts! Also avoid wet wipes or alcohol: liquid can get inside the case and cause corrosion.

After cleaning, insert and remove the headphones several times, which will help to “reset” the connection sensor. If the problem was pollution, the sound should return to the phone speakers.

Method 3: Resetting the sound settings in MIUI

If physical cleaning and rebooting didn't help, the problem may lie in the audio settings. MIUI has a hidden audio reset option that often solves problems with a "stuck" headset.

How to reset the sound settings:

1. Open Settings (the gear icon on the main screen).
2. Go to the section Sound and vibration.
3. Scroll down and select Additional Settings (or Advanced in English).
4. Find Reset sound settings (could be called Reset sound settings) and confirm the action.

Once reset, the phone will automatically restart, which does not delete user data (photos, contacts, messages), but returns volume, notifications and sound profiles to factory settings.

If your MIUI version does not have a “Reset Sound Settings” option, try an alternative method:

1. Open "Settings" → "Applications" → "Application Management".


2.Look for the Sound (or Audio) app and click on it.




3. Select "Storage" → "Clear Data" and "Clear Cache".




4. Reboot the phone.

⚠️ Attention: Clearing the Sound app data will reset all your individual settings (e.g., uniform volume or sound effects) and you will have to reset them.

Method 4: Use of the Engineering Menu (for advanced users)

If standard methods don't work, you can try the engineering menu, the hidden settings section where low-level audio settings are available, which is suitable for advanced users, as careless actions can lead to failures.

How to open the engineering menu on Redmi Note 7:

1. Open the phone (calling) application.
2. Enter the combination: ##36446337## (this is the code for MediaTek processors that are in Redmi Note 7).
3. You will be taken to the Engineering Mode menu. Go to the Hardware Testing → Audio section.
4. In the Headset Mode submenu, select Normal Mode (if you have a Headset or Headphone).
5. Save the settings and restart the phone.

If the headset is still active after these steps, check the other options in the engineering menu:

• 🔊 Headset Impedance – should be 32 Ohm (standard for most headphones).
• 🔌 Headset Detection – Turn on and off this setting to reset the sensor.
• 🔄 Audio Loopback Test – Run the test and wait until it is completed (helps to reset the audio driver).

Be careful: changing other settings in the engineering menu can lead to loss of sound or other problems. If you are not sure, it is better not to touch unfamiliar settings.

💡

Before entering the engineering menu, back up the data. In rare cases, incorrect settings can cause a system failure.

Method 5: Resetting the phone to factory settings (last resort)

If none of the previous methods worked, it's a radical solution that will bring the phone back out of the box, eliminating all software errors, but remember, resetting will remove all data from the device -- photos, videos, messages, apps -- so back up first!

How to reset Redmi Note 7 to factory settings:

1. Open the Settings. → The phone.
2. Select Reset options (or Reset options).
3. Click Erase all data (reset to factory settings).
4. Enter a password (if required) and confirm the action.
5. Wait for the process to be completed (it will take 5-10 minutes).

Once you reset, the phone will reboot, and you'll have to reconfigure it, just like you did after you bought it, and if the problem was software, the headset should no longer stick.

⚠️ Warning: If the problem persists after the reset, it almost certainly indicates a hardware malfunction (damage to the connector or audio chip.

What to do if nothing helps: Diagnostics of hardware problems

If you've tried all the ways, but the Redmi Note 7 still sees a non-existent headset, it's probably a problem with the hardware.

If you suspect a hardware malfunction, don’t try to repair the phone yourself, which could make the problem worse. Contact Xiaomi’s official service center or a trusted repair center.The average cost of a diagnosis is 500–1,000. ₽, replacement of the connector - 1000-2000 ₽.

Before the service visit:

• 📋 Write down when the problem occurred (after a drop, update, etc.).
• 🔋 Make sure the phone is charged (the master may need to test it).
• 🔄 Do a reset (if you haven’t done it before) – this will eliminate a software error.
