Modern Xiaomi, Redmi and POCO smartphones come with powerful multimedia capabilities, but standard audio settings often don’t reveal them completely. Many users notice that the music sounds flat, and in games you can’t determine the exact direction of your opponent’s steps, and this is where the built-in sound presets and advanced equalizer settings come to the rescue.
Understanding how these algorithms work turns a budget model’s mediocre sound into a quality audio experience, and in this article we’ll go into detail about what’s behind the term “preset,” how to adjust frequencies correctly, and what hidden features are available in the MIUI and HyperOS shell.
Don't ignore these settings, because they affect not only the volume, but also the purity of the high frequency transmission and the depth of the bass. Proper calibration can significantly improve the perception of content without buying external accessories.
What is a sound preset in the Xiaomi system
The preset is a pre-prepared set of digital signal processor (DSP) parameters that changes the frequency characteristics of the audio stream. In Xiaomi devices, these settings are based on Dolby Atmos technologies or the company's own developments, such as Mi Sound. Preset automatically applies equalizer curves, dynamic range compression and virtual surround sound.
When you select Music mode, the system emphasizes medium and high frequencies, making the vocals clearer. In Movie, the algorithm expands the stereo and amplifies low-frequency effects to create a cinematic experience. It's not just a change in volume, it's a complex mathematical processing of the signal in real time.
⚠️ Attention: Excessive bass reinforcement in presets can lead to wheezing (clipping) at the maximum volume of the built-in speakers».
The user can not only choose the scripts, but also create their own profiles, which is especially important for owners of headphones of different types, because the acoustic signature is different for everyone, and the system remembers these settings for each connected device separately.
Where to find sound and equalizer settings
Access to managing audio options in the MIUI or HyperOS shell may not be obvious to a beginner, as the menu is often scattered across sections. The main path is through the standard smartphone settings menu. You need to go to Settings → Sound and Vibration.
This is where the Dolby Atmos switch (if the model supports this technology) and the Advanced Settings Login button are located. In some regions or on certain firmware versions, this section may be called "Sound Quality and Effects." Inside, you'll find balance sliders and scenario selections.
Hidden codes for sound verification
For more fine-tuning, including manual frequency control, look for the Equalizer or Mi Sound item. If you use wired headphones, the menu can only activate once they're connected. Wireless Bluetooth headsets often have their own profiles that prioritize the system.
- 🎧 Headphones: Separate menu for wired and Bluetooth devices.
- 📢 Dynamics: Global settings for hands-free and media.
- 🎮 Game mode: Specific settings for horizontal position.
- 🔊 Alarm clock: Separate volume control for system notifications.
A review of popular presets and their impact on sound
Xiaomi’s standard set typically has about 6-8 presets, each tailored to a specific genre or type of content, and understanding the differences between them will allow you to choose the best option for your current situation, whether it’s listening to a podcast or playing a first-person shooter.
Auto mode attempts to analyze the content being played and switch between profiles on the fly, but in practice this algorithm often works incorrectly, so many experts recommend choosing a static profile manually, which provides predictable results.
Balanced mode tries to keep the original recording free of severe distortions. It's suitable for news channels and audiobooks. Bass Boost dramatically raises frequencies below 100Hz, which is good for electronics, but can swallow the middle. Vocal mode cuts out low frequencies and emphasizes the range of the human voice.
| preset | Low frequencies | Mid-frequency | High frequencies | Best application |
|---|---|---|---|---|
| Balance | 0 dB | +1 dB | 0 dB | News, podcasts |
| Bass. | +4 dB | -1 dB | +1 dB | Hip-hop, EDM |
| Vocals | -2 dB | +3 db | +1 dB | Audiobooks |
| Bright | 0 dB | +1 dB | +3 db | Classic, jazz |
Manual equalizer setting for different genres
If you don't like presets, manually adjusting the equalizer gives you complete control of the sound. In the Mi Sound interface, you see a graph with sliders corresponding to different frequency bands, and by moving them, you can compensate for the shortcomings of the speakers or headphones.
Rock and Metal are characterized by an emphasis on guitars and drums. It is recommended to slightly raise the frequencies in the area of 2-4 kHz for attack and add air to 10-16 kHz. Bass should be left at the middle level so that they do not overlap the rhythm section.
⚠️ Note: When manually adjusting, avoid sharp jumps in values (more 3-4 dB) between adjacent sliders, which creates phase distortion and renders the sound unnatural and glassy».
For electronic music, a powerful low-frequency base is important. Raise the sliders in the 60-100 Hz range. However, remember the physical limitations of the smartphone speakers. If you hear a crackle, turn down the gain in this area. High frequencies can be raised for synths to be heard.
💡
Save your equalizer settings as a custom preset if available. When you reset or update your system, custom profiles may be lost and you will have to reconfigure them.
Optimizing sound for games and movies
Gamers value Xiaomi and POCO smartphones for their low latency and spatial audio location. In gaming presets, the Dolby Atmos algorithm works differently: it amplifies steps, shots and recharges, making them more distinguishable against the background of music and environmental effects.
Dynamic range is critical for movies; quiet dialogue should be heard and explosions should not be stunned; turn on Night Mode or Compressor if available in your version of firmware; this levels the volume, making quiet sounds louder and louder.
- 🎯 Localization: Improves understanding of which side of the sound is coming from.
- 💥 Dynamics: Makes explosions more spectacular without distortion.
- 🗣️ Dialogue: Selects the frequency of the human voice from the mix.
- 🔋 Energy efficiency: Some modes save charge by reducing processing quality.
Owners of the Black Shark series or flagship Xiaomi 13/14 Ultra are available additional settings in the game accelerator (Game Turbo), where you can customize the sound scene for each installed game, which is a unique feature of the ecosystem.

Sound problems and how to solve them
Even with perfect settings, users can run into problems, and it's common to see the sound become quieter after a system update, and this could be due to resetting regional volume limits or driver conflict.
If the sound is missing in the headphones, but it is in the speakers, check the settings of Bluetooth codecs. In the menu for developers (Settings → About the phone → 7 times tap on the version MIUI → Advanced settings → For developers), you can change the codec from SBC to AAC or aptX, which often solves the problem.
⚠️ Warning: If the sound is gone and doesn't appear even after the reboot, don't rush to bring the phone to the service. Try running the speaker engineering test code ##6484##. If the test shows an error, the hardware problem is not easy.
The wheezing of speakers is often caused not by a breakdown, but by a contamination of the speaker grid or a software stopper. Careful cleaning with a soft brush and lowering the bass level in the equalizer can save the situation, and it is also worth checking whether the Mono-audio feature, which is sometimes activated accidentally in the special features section, is included.
💡
Most software problems with sound are solved by resetting the sound settings to factory or switching the region in the smartphone settings to India or Singapore (where the volume limits are softer).
