How to Turn Off the Stereo Sound on Xiaomi Phone: A Complete Guide to All Models

Stereo sound on Xiaomi smartphones can be uncomfortable in some situations: listening to music through a single earpiece, during phone conversations using a headset or when connecting to external speakers. Many users face the problem when sound is distributed unevenly between left and right channels, which is especially critical for people with hearing impairment. In this article, we will examine all possible ways to turn off the stereo effect on Xiaomi devices, from standard settings to hidden engineering menus.

It's important to understand that the manufacturer doesn't always provide a direct option to switch to mono mode, and this is due to the architecture of the MIUI sound system, where stereo sound is considered a standard format. However, there are workarounds, including using third-party applications, changing system settings through ADB, and special settings for users with disabilities. We tested all methods on models from the Redmi Note 10 to Xiaomi 14 Ultra, the results are presented in the comparative table below.

Why Xiaomi smartphones use stereo sound by default

Modern Xiaomi smartphones are equipped with two speakers (bottom and top), which creates a surround sound effect, this technology is called dual stereo speakers and is used for:

• 🎵 Improve the quality of music and video playback
• 🎮 Immersion in games with spatial sound
• 📞 Increased voice legibility in hands-free communication

But there are also disadvantages to this approach: for example, when you connect wired headphones with a faulty channel or use a single wireless earphone (TWS), some of the audio information is lost, and users with unilateral hearing loss may have difficulty perceiving speech if it is broadcast in only one channel.

Interesting fact: on some models (for example, the POCO F5), the stereo effect is implemented programmatically even when using a single speaker, which means that the sound is artificially divided into channels, which can create the illusion of spatial sound, but at the same time complicates the process of turning it off.

Method 1: Use of special features settings

The easiest method is to activate mono audio mode through the special features menu, which works on all devices with MIUI 12 and later, including Redmi, POCO and Xiaomi’s flagship models.

Instructions:

1. Open the Settings.
2. Go to Special Features (on some firmware – Additional Features)
3. Choose Rumor → Mono Sound
4. Activate the switch to turn on the mono sound
5. Set up the balance between channels with a slider (default: 50/50)

This method has a limitation: it only works for media files and system sounds, calls and notifications will remain in stereo format, and additional methods will be required to completely disable stereo in all scenarios.

Check the version of MIUI in Settings → About the phone

Method 2: Change the sound parameters through the engineering menu

For advanced users, it is possible to turn off stereo audio via an engineering menu (MTK Engineer Mode or Qualcomm Diag, depending on the processor), a method that requires caution, as incorrect changes can lead to malfunctions in the audio system.

Step-by-step instructions for devices on Qualcomm Snapdragon:

1. Enter the code in the phone application: ##36446337##
2. In the menu, select Hardware Testing → Audio
3. Go to Speaker Test or Headset Test (depending on your script)
4. Find the Stereo Mode option and set Mono or Disabled
5. Save the settings and restart the device

For devices on MediaTek, use the code:

Important: On models with a Snapdragon 8 Gen 2 processor (Xiaomi 13 Pro, POCO F5 Pro), the change in the parameters in the engineering menu may reset after the MIUI update.

Method 3: Applications for forced mono sound

If the standard methods don't work, you can use third-party applications. We tested 5 popular solutions, the results in the table below:

The most versatile solution is Samsung’s SoundAssistant, which, despite its origins, works perfectly on Xiaomi.

• 🔊 Forced to include mono mode for all exits
• 🎧 Balance between channels with an accuracy of 1%
• 🔔 Turn off the stereo effect for notifications and alarms

💡

If the sound disappears completely after installing the application, check the permissions for the application in Settings → Applications → Special Access → Change the system settings.

Method 4: Disabling stereo through ADB-teams (without root)

For users who are willing to work with ADB, There's a method of forcing stereo to be turned off through system commands, which doesn't require root rights, but requires a computer and a computer. USB-cable.

Instructions:

1. Enable USB Debugging in Settings → About Phone → MIUI Version (click 7 times) → Additional Settings → Developer Settings
2. Connect your phone to your PC and confirm your debugging permission
3. Open the command line and enter:

adb shell settings put global force_mono_audio_output 1

1. Reset the device

To return to stereo sound, use the command:

adb shell settings put global force_mono_audio_output 0

This method works at the system level and affects all audio outputs, including:

• 🎧 Wired and wireless headphones
• 📢 Built-in speakers
• 🔌 USB-C and Bluetooth audio devices

💡

ADB-The only way to completely disable stereo sound at the system level is without superuser rights. MIUI parameter may reset.

Solving problems after turning off stereo sound

After using any of these methods, you may experience side effects, and here are the most common problems and solutions.

⚠️ Warning: If the sound in your headphones is gone after changing the audio settings, check the physical connection. 12T and more recently, a moisture protection system is used, which can block the audio output when a short circuit is detected.

On models with Dolby Atmos (Xiaomi 13 Pro, Redmi K60 Pro) may require additional shutdown of spatial sound:

1. Go to Settings → Sound and vibration → Sound quality
2. Disable Dolby Atmos or set a music profile instead of a movie

Features for specific Xiaomi models

Some devices have unique sound architectures that require a special approach:

For POCO F3/F4/F5: These models use Dual Smart PA technology, which automatically switches between mono and stereo modes.

1. Install the POCO Launcher app (even if you have a different shell)
2. In its settings, find the section Sound effects
3. Turn off the Adaptive Sound option.

For Xiaomi 11T/12T: These devices are stereo effected through Harman Kardon.

1. Go to Settings → Additional settings → Sound effects
2. Choose a Flat Profile instead of Harman Kardon
3. Turn off headphone virtualization

For Redmi Note 10/11/12: These models have a hardware problem with the left speaker on some batches.
