You took out a Xiaomi Redmi smartphone to listen to music or answer a call, but instead of sound from the speakers, you see the headphone icon in the status bar? And the headphones themselves are not connected, either by wire or Bluetooth. This error occurs on Redmi Note 10/11/12, Redmi 9/10/12C and even the flagships of POCO F4/X5. 80% of the time, the problem is solved in 5 minutes, but sometimes requires deep diagnosis.
The error occurs due to a failure in the audio chip, incorrect Bluetooth settings, contamination of the Type-C/3.5 mm connector or software conflicts after updating MIUI. In this article, step-by-step instructions from simple (reboot) to complex (resetting), as well as unique ways for models with a 3.5 mm connector and USB-C. If after all the manipulations, the headphone icon remains - this is an occasion to check the hardware condition of the smartphone.
Why Xiaomi Redmi "sees" headphones that don't exist?
The reason is because the device detects the connected devices, because the smartphone analyzes the resistance in the audio jack or the signals from the Bluetooth module, and if the data is distorted, the system mistakenly "thinks" that the headphones are connected. Common triggers:
- 🔌 Connector Pollution: Dust, moisture, or oxidation of 3.5mm or Type-C contacts simulate device connection.
- 📱 Failure MIUI: post-update MIUI 13/14 or resetting the audio driver settings is not working properly.
- 🔄 Bluetooth conflict: If wireless headphones were previously connected, their “ghost” may remain in the system.
- 🛠️ Audio chip damage: physical impact (fall, moisture) or overheating leads to false signals.
On Redmi models with a 3.5 mm connector (e.g. Redmi 9A/10A), the problem is more often associated with mechanical contamination. Type-C devices (Redmi Note 11 Pro+, POCO X4 GT) are to blame for software failure or damage to contacts inside the port.
Diagnosis: How do you know what the problem is?
Before you start the correction, check 3 key points:
- Physical condition of the connector: illuminate the flashlight to the port 3.5 mm/Type-C. Whether foreign objects, oxidation or bent contacts are visible?
- Behavior of the icon: Does the headphone icon disappear after rebooting? Does it only appear when you plug in the charging?
- Sound through speakers: Have you tried to play music or video? Is there sound if you plug in real headphones?
If the icon disappears after the reboot, but comes back after a while, it is the software that is to blame. If the icon does not disappear even after the reset, the problem is in the hardware.
Enter the code ##4636##| Select Phone Information | Scroll to Audio | Check the status of "Wired Headset" (should be "unplugged")
-->
##4636##In the Audio unit, look at the Wired Headset setting, if it shows plugged despite the absence of headphones, it confirms a software glitch. On some MIUI firmware, the engineering menu may be blocked. Alternatively, use the MTK Engineering Mode app (for MediaTek-based devices).
⚠️ Warning: Do not change other options in the engineering menu without understanding their purpose.
7 working ways to remove the icon headphones
Start with the simplest methods and move on to the hard ones if the problem is not solved.
1. Reboot and check the connector
In 30 percent of cases, the basic reboot helps. Press the power button, select Reboot and wait for the power to turn on.
- 🧹 Clean the connector carefully. 3.5 mm/Type-C toothpick (not a metal object!).
- 🔌 Connect and disable real headphones 2-3 times – it can “reset” the state of the port.
2. Cleaning the cache of the "Phone" application
The crash may be related to the cache of the system application. Go to Settings → Applications → Application Management → Phone (or System Applications). Click Storage → Clear cache.
3. Reset Bluetooth settings
If wireless headphones used to be connected, their data could be stuck in the system. Open Settings → Bluetooth, delete all the stored devices, then:
- Turn off Bluetooth.
- Reboot the phone.
- Turn on Bluetooth again.
4. Enabling/disabling the developer mode
Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone). Then go to Settings → Additional → For Developers and:
- 🔇 Turn off the absolute volume level (if enabled).
- 🔄 Switch debugging to USB (off).
5. Reset all settings
If previous methods didn’t work, reset your settings (without deleting data). Go to Settings → About Phone → Reset → Reset all settings. This will return the audio, network and Bluetooth settings to factory settings.
⚠️ Warning: After reset, you will have to reconnect Wi-Fi, adjust your fingerprint and other settings, and backups of applications (such as Mi Cloud) will be saved.
6.Update or rollback MIUI
The error may appear after the firmware update. Check the relevance of the version in Settings → About Phone → System Update. If the problem occurred after the update, try to roll back to the previous version via Fastboot (the 4PDA instruction for your model).
7. Hardware diagnostics
If none of these things work, it's because of damage to the audio chip or the connector contacts. 1 500–4 000 ₽ depending on the model. 10/11 Type-C port replacement is required. 1 200 ₽), for old models with 3.5 mm - cleaning or soldering contacts.
💡
If the headphone icon only appears when you connect the charger, the problem is short-circuit Type-C contacts. Do not use the phone in this state: this can damage the battery.
What do you do if nothing helps?
If after all the manipulations the headphone icon remains, and the sound through the speakers is not restored, there are 3 options:
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Fastboot flashing through Fastboot | ⭐⭐⭐⭐ | 80% | Data loss, brick devices |
| Replacement of audio chip | ⭐⭐⭐⭐⭐ | 95% | High cost (from 3,000) ₽) |
| Use of an external Bluetooth adapter | ⭐ | 100% (bypass) | Inconvenience, additional costs |
Fastboot will require an unlocked bootloader and PC. Instructions are available on thematic forums (such as 4PDA or XDA-Developers) for your model. The alternative is to connect Bluetooth headphones and use them as the main source of sound, turning off speakers in the settings.

Xiaomi Redmi models with frequent sound problems
Some devices are more prone to audio jack errors, and in the table you can see the models that have the problem more often than others, and the typical reasons:
| Model | Type of connector | Frequent cause of failure | Recommendation |
|---|---|---|---|
| Redmi 9A/9C/10A | 3.5 mm | Contact oxidation, dust | Cleaning with alcohol, switching the connector (~800 ₽) |
| Redmi Note 10 Pro | Type-C | Failure after upgrade to MIUI 13 | Firmware rollback or reset settings |
| POCO X3 Pro | 3.5 mm | Conflict with Bluetooth headphones | Resetting Bluetooth settings |
| Redmi Note 11 Pro+ | Type-C | Damage to the audio chip when falling | Diagnostics in the service |
For Redmi with a 3.5 mm connector (Redmi 9/10 series), mechanical cleaning is more likely to help. For Type-C devices (Redmi Note 11/12, POCO F4), software methods (reset, flashing) are more effective. If your model is not on the list, focus on the type of connector.
💡
On the Redmi Note 10S and POCO M4 Pro models, the bug is often associated with the Mi Sound Enhancer application conflict. Disable it in the audio settings or remove updates through Settings → Apps → Remove updates.
Prevention: How to avoid problems in the future
To avoid repeating the error, follow the following simple rules:
- 🛡️ Use covers with protection of connectors from dust and moisture.
- 🔌 Avoid cheap headphones with a bad plug – they damage contacts.
- 📱 Don't update. MIUI In the first days after the release – wait for reviews about bugs.
- 🔄 Clean the connectors regularly with a dry toothpick (1 time in 2-3 months).
If you use Bluetooth headphones frequently, forget the device in the settings before you turn it off, rather than just turning it off. This will prevent the connection from hanging. For Type-C models, only use certified cables — cheap accessories can damage the contacts that recognize the headphones.
