Xiaomi Redmi Note 10 S is equipped with stereo speakers and support for Dolby Atmos technology, which makes it an excellent multimedia device for listening to music and watching movies. However, factory audio settings are often averaged, without revealing the full potential of the acoustic system or connected headphones. Many users do not even suspect that the hidden capabilities of the MIUI audio engine allow you to radically change the sound by adding bass or clarity to high frequencies.
Turning on the built-in equalizer is the first step to personalizing the audio stream, which does not require installing heavy third-party software or obtaining superuser rights. The Android system in the MIUI shell provides flexible tools for frequency correction, but access to it is sometimes hidden in non-obvious menus or activated only when you connect the headset. Understanding the logic of the sound engine will allow you to squeeze the most out of the device.
In this guide, we will take a look at all the ways to activate and fine-tune sound, from standard system tools to professional applications, how to get around the limitations of a standard interface and what settings can negatively affect the quality of playback if used thoughtlessly. Proper calibration will turn your smartphone into a portable Hi-Fi player.
Standard sound settings in MIUI
The basic audio control layer is in the system settings menu, which can be accessed through the gear in the notification curtain or through the Settings app. This is where the main surround technology switch, which is the key to advanced features, is located. Without activating this mode, many equalizer sliders may remain inaccessible or operate in a limited range.
To access the basic settings, go to the Sound and Vibration section, where the volume sliders for media, call and alarm are located. Below you will find the Dolby Atmos item that you need to activate. Once activated, the system will prompt you to select a profile: Automatically, Film, Music or Voice. Selecting a Music profile often automatically unlocks access to the graphic equalizer in some versions of the firmware.
⚠️ Warning: Activating Dolby Atmos may slightly increase battery consumption, as the processor will spend additional resources processing the audio stream in real time.
Importantly, the menu interface may vary depending on the version of MIUI (Global, Russia, China). In some builds, the equalizer is put into a separate menu when you connect the headphones, while in others it is always available. If you don't see the frequency sliders, try connecting a wired headset or Bluetooth headphones - this often serves as a trigger for additional settings.

Activation via the Sound and Vibration menu
Deep frequency tuning is often hidden inside the submenu of sound effects. To get to them, you need to go through the Sequence of Adjustments → Sound and Vibration → Sound Effects. This is the same graphical equalizer that allows you to manually raise or lower the decibel level at specific frequencies.
The interface is a set of vertical sliders, each of which is responsible for a different range from low bass to high-pitched frequencies. By moving the sliders, you can create your own sound profile, for example, to enhance bass for electronic music or add brightness to vocals. The system allows you to save several user profiles, which is convenient for different genres.
Be careful with extreme values of sliders. Excessive amplification of low frequencies can lead to wheezing in the smartphone's dynamics, since the physical size of the speaker is limited. Xiaomi Redmi Note 10 S has good speakers, but they are not unlimited in their amplitude of oscillations.
| Frequency range | Impact on sound | Recommendation |
|---|
| 60 Hz - 200 Hz | The depth and power of bass | Raise carefully to avoid wheezing |
| 400 Hz - 1 kHz | Warmth of sound, vocals | Leave close to zero for naturalness |
| 2 kHz - 4 kHz | Attack of sound, clarity of instruments | You can add it for detail. |
| 8 kHz - 16 kHz | Air, hiss, space. | Raise for the effect of presence |
Xiaomi’s standard player, simply called Music, has its own built-in equalizer that works regardless of system settings, which is handy if you use different apps for different tasks and want the settings to be applied only within the same player, and you can run it through the note icon on your desktop or in the Tools folder.
Inside the app, click on the settings icon or sound effects icon (often looking like notes or equalizers). Here you will find the Mi Sound Enhancer switch, which is the company's proprietary development to improve sound quality. Unlike the Dolby system, this effect is tailored specifically to the media playback algorithms.
The Mi Sound Enhancer
This mode uses algorithms to compensate for audio compression, recovering lost during conversion to MP3 High frequencies. It works best with high-end wired headphones.> The user interface is more minimal, but functional, and you can choose presets (Pop, Rock, Jazz) or create your own. It is important to understand that the settings in the Music app can overlap the system settings if both equalizers are active at the same time, which will lead to distortions. ⚠️ Attention: Simultaneously turning on the system equalizer and equalizer in the player can cause digital distortion (clipping), making the sound unpleasant and sharp. MIUI Google Play Store offers a lot of advanced solutions. The leader in this niche is already the Poweramp Equalizer app, which intercepts audio streams and applies its processing algorithms. It supports multiband equalizers, parametric filters and various effects. Another popular option is Flat Equalizer or Bass Booster. These applications often have a simpler interface, but provide access to the Android system audio mixer at a deeper level than standard settings. Installing such software requires permissions to access media files and, in some cases, special permissions through ADB. When using third-party software, you need to avoid built-in audio mixing, only achieves stable improvements in the entire chain of the active use. This rule is especially true for owners of Redmi Note 10 S with its sensitive acoustics. Secrets of the engineering menu and Mi Sound For advanced users, there is the possibility of accessing hidden audio settings through the engineering menu or special codes. Entering the code ##6484# opens the testing menu where you can check the performance of speakers, but not always configure them. However, there are hidden flags in the developer menu that can unlock additional options. To get into the developer menu, you need to quickly click on the build number in the About section seven times. Then, in the “Developers” menu, you can search for the audio code related to absolutely switch off the wireless code. Mi Sound (not to be confused with Mi Sound Enhancer in the player) is sometimes found in global firmware called Sound Improvement, which automatically adjusts the frequency response to the type of connected headphones (intrachannel, overhead). If your firmware region does not support this feature, it can be activated through configuration files, but it requires root rights. 💡Engineering codes and developer menus are a powerful tool, but changing unknown parameters can cause audio drivers to fail. Despite the reliability of the Xiaomi Redmi Note 10 S, users may encounter a situation where the equalizer simply does not turn on or the settings are reset after a reboot. MIUI, It kills the background processes of audio services. The solution lies in the battery settings. You need to go to the settings of the application responsible for sound (whether it is a system service or a third-party equalizer) and select the battery mode "No restrictions", and you should also fix the application in memory by opening a list of running processes and pressing the lock. This will prevent the service from unloading from RAM. 🔊 Problem: Sound became quieter after adjusting the equalizer.Solution: Reset the equalizer settings to the factory settings, you may have created a negative curve. 🎧 Problem: Equator doesn't work with Bluetooth headset.Solution: Enable the "Unplug Absolute Volume" option in the developer menu. 📉 Problem: There's a wheezing at maximum volume. Solution: Lower the sliders (60-100 Hz. 2-3 dB. If software methods do not help, it is worth checking the physical condition of the speakers. Dust in the grid speaker can create the illusion of sound distortion that no equalizer can fix. Careful cleaning with a soft brush often works wonders. Does the equalizer affect the recording quality of the recorder? No, the standard equalizer only affects the playback (output). To change the quality of the record, you need to look for settings in the voice recorder application itself or use third-party recorders with support for input settings. Can I save my equalizer profile? In the standard interface. MIUI The user profile is often limited, but if you use Dolby Atmos, the Music profile remembers your latest changes, third-party apps allow you to save unlimited presets, and if you reset after the update. MIUI? Major shell updates (e.g., switching from MIUI 12 to 13) can reset the system's audio settings to factory ones. It's recommended to take screenshots of successful configurations before upgrading. Why is the equaliser gray and inactive? This often happens if the system activates Do Not Disturb mode or has a device with its own audio processor that intercepts control. Also check if mono-sound mode is included in special.
