You plugged your headphones into Xiaomi, but when they're disconnected, your phone still thinks they're connected? The sound only goes to the "invisible" headphones and the speakers are silent? This is a common problem on MIUI devices that comes from an audio jack failure, software glitch, or mechanical damage. In 80% of cases, the headphone mode shuts down in 2 minutes -- you just need to know where to look for settings.
In this article, we will analyze all possible reasons for activating the headphone mode on Redmi, POCO and other Xiaomi smartphones, as well as give step-by-step instructions for their elimination - from basic (reboot, cleaning the connector) to advanced (resetting sound settings through the engineering menu). Particular attention will be paid to situations where the headphone mode turns on by itself after a phone drop or update. MIUI β This often signals damage to the plume or contacts.
Why Xiaomi is βhangingβ in headphone mode?
Before you start fixing, it's important to understand the root of the problem: Headphone mode is activated automatically when you connect a 3.5mm headset or wireless headphones over Bluetooth. If the device doesn't switch back to speakers after you turn it off, it may be:
- π Pollution or oxidation of contacts in the audio connector (dust, moisture, rust).
- π€ Software failure in service media.audio_policy (frequently MIUI).
- π§ Mechanical damage to the plume of the audio connector (after falling or hitting).
- π± Conflict of applications that control sound (levels, modified firmware).
- π Incorrectly disabling Bluetooth headphones (if they were connected last).
On Xiaomi devices with MIUI 12-14, the most common problem is a bug in the audio management system. For example, after connecting the headphones via Bluetooth, the phone can βforgetβ to return the sound to the speakers. In older models (for example, the Redmi Note 5 or Mi A2), the physical connector is to blame β its contacts wear out over time.
β οΈ Warning: If headphone mode appears after a phone drop or moisture hits, don't try to clean the connector yourself, which can aggravate the damage.
Method 1: Basic actions (reboot and check connector)
Start with the simplest steps β they help 60% of the time:
- Reboot your phone. Hold the power button for 10 seconds until the screen goes out, then turn the device back on, which resets the audio system's temporary settings.
- Check the 3.5 mm connector. Connect and disconnect the headphones 2-3 times - sometimes the contacts "stick" in the "connected" position.
- Clean the connector. Use a toothpick (carefully!) or compressed air to remove the dust. Don't use metal objects!
- Turn off Bluetooth. If the last wireless headphones were connected, go to Settings β Bluetooth and turn them off.
If the sound doesn't come back, move on to the next way, and if the phone responds to the headphones being connected/disabled (e.g., a notification appears), but the sound still goes to the invisible headphones, which is a software problem.

Method 2: Forced resetting of sound settings via MIUI
If the basics don't work, reset the audio settings to factory settings, and it won't delete your data, but it will return all the audio settings to their original state.
- Open the Settings. β Sound and vibration.
- Slip on the three dots in the upper right corner and select Reset.
- Confirm the action. The phone will reboot.
After the reboot, check the sound. If the headphone mode is still there, try plugging and turning off the headphones again - sometimes resetting only helps after a repeat "trigger."
β οΈ Note: On some models (POCO F3, Redmi Note 10 Pro may not be available for resetting. In this case, use method 3 (engineering menu).

Method 3: Engineering menu (for advanced users)
If standard methods don't work, try resetting the audio settings through the engineering menu, which is suitable for all MIUI devices, but requires caution:
- Open the Phone app and type the combination: ##36446337### Some models may work ##4636##.
- Choose Hardware Testing β Audio.
- In the Headset Mode section, set the Disabled value.
- Save the settings and restart the phone.
If the engineering menu doesn't open, it may be blocked by the manufacturer, in which case try method 4 (ADB reset).

Method 4: Reset via ADB (for power users)
If previous methods didnβt work, try resetting the audio settings via ADB (Android Debug Bridge).
- Turn on Developer Mode on your phone: go to Settings β About Phone and tap the MIUI version 7 times.
- Return to Settings β Additional β For developers and enable USB debugging.
- Connect your phone to your PC, open Command Prompt (Windows) or Terminal (Mac/Linux) Enter: adb shell settings put global headset_state 0 Then do: adb shell am broadcast -a android.intent.action.HEADSET_PLUG --ez state 0 --ez microphone 0
- Reboot the phone.
These commands force the system to tell the headphones that they're off, and if the sound doesn't come back after the reboot, it could be hardware.

Before using ADB, install the official Xiaomi drivers and Minimal ADB and Fastboot program.
Method 5: Hardware malfunctions (when nothing helps)
If none of the software methods worked, the problem is probably hardware.
| Reason. | Signs. | Decision |
|---|---|---|
| The audio connector's plume is damaged. | Headphone mode is turned on after falling, the sound disappears when the phone moves | Replacement of the plume in the service (cost: 1000-2 500) β½) |
| Oxidation of connector contacts | The sound appears, then disappears, the connector blackened | Cleaning with alcohol or replacing the connector (500-1 500) β½) |
| Failure of the audio codec | There is no sound through the speakers or through the headphones. | Replacement of the motherboard (expensive, often impractical) |
| Moisture intrusion | Phone falls into water, sound distorted or missing | Diagnosis for corrosion, replacement of damaged components |
If youβre not sure why, take the phone to Xiaomiβs service center.Diagnostics is usually free and repairs are cheaper than trying to fix yourself (risk damaging the fee).

If the headphone mode appeared after mechanical impact (hit, fall), 90% is a hardware problem. Don't waste time on software methods - contact the service.
