Xiaomi’s modern smartphones have long since ceased to be just callers, becoming powerful multimedia centers where audio quality is as much a priority as processor performance. Device owners often face a situation where standard volume settings are not enough and require more subtle calibration for a particular genre of music or listening conditions. This is where sound effects come to the rescue that allow you to radically change the nature of the sound of speakers or connected headphones.
Understanding how these settings work and where they are located is critical for anyone in the Xiaomi, Redmi or POCO ecosystem. The interface of the MIUI shell, and now the new HyperOS, hides a host of audiophile tools that often go unnoticed due to the complex structure of the menu. In this article, we’ll take a closer look at all the available ways to improve sound, from simple switches to advanced equalizer settings.
What is hidden under the concept of sound effects
Sound effects in the context of mobile devices are software-based digital signal processing (DSP) algorithms that change the original audio stream before it is fed to the speaker. Unlike simple volume gain, these algorithms can adjust the frequency range, add virtual surround sound or compensate for the acoustic shortcomings of embedded speakers. For Xiaomi smartphone owners, this means the ability to get studio-quality sound without buying additional equipment.
The system layer of sound processing in Chinese devices is usually based on a bundle of standard Android tools and proprietary add-ons. Dolby Atmos is one of the key components for spatial sound, but it works in tandem with a system equalizer. It is important to understand that the application of effects is always a compromise between the purity of the original signal and the desired nature of the sound.
⚠️ Attention: Excessively amplifying low frequencies or activating maximum virtualization levels can lead to distortion and wheezing, especially at the maximum volume of embedded speakers.
Different smartphone models support a different set of features: flagship Xiaomi 13 or Xiaomi 14 lines often have more advanced codecs and support for Hi-Res Audio, while budget models can be limited to a basic set of presets. However, even on initial devices, you can significantly improve the perception of content by properly configuring the software part.
💡
Use quality wired headphones or Bluetooth headsets with support for aptX HD or LDAC codecs to unlock the potential of advanced sound effects.
Where to find audio settings in MIUI and HyperOS
Finding the right settings can be confusing for a beginner, as Xiaomi constantly changes the location and location of menu items in different versions of the firmware. The basic path to managing audio always lies through the main settings menu, but the depth of immersion depends on the installed version of the operating system. In current builds of HyperOS, the logic of grouping has become more intuitive, but the usual paths in MIUI 14 are still relevant for millions of devices.
To get to the main controls, you need to go to Settings, then select Sound and Vibration, and that's where the system switches, alarm volume and, most importantly, access to advanced settings are concentrated. Depending on the firmware region (Global, Chinese, European), the names of the items may vary slightly, but the structure remains the same.
- 🎵 The path to the equalizer: Settings → Sound and vibration → Sound quality and effects (or audio effects).
- 🔊 Volume setting: Settings → Sound and vibration → Volume (separate adjustment for media, bell, alarm clock).
- 🎧 Headphones: Settings → Sound and vibration → Headphones (button management settings and improver).
In some cases, especially on older versions of shells, access to advanced settings may be hidden inside the "Advanced" menu. If you don't see "Sound Quality" right away, take a closer look at the top right corner of the screen or scroll to the bottom. It's also worth noting that some features depend on the version of the "Security" app installed and system components.
Equalizer and presets of sound
The centerpiece of Xiaomi’s audio customization is the graphical equalizer, which allows users to manually change the amplitude of signals across a range of frequencies, from deep bass to high frequencies. For those who don’t want to understand hertz and decibels, the system offers a set of presets optimized for different genres of music.
The standard set typically includes Rock, Pop, Jazz, Classic and Dance Music modes. Each of these modes is a pre-arranged profile where certain frequencies are raised and others are muted. For example, Rock mode typically enhances the average frequencies for guitar allocation, and Dance music emphasizes low frequencies for powerful bass.
For advanced users, you can manually customize sliders, you can create your own profile that is perfect for your acoustic system or a particular headphone model, and you can experiment with the position of sliders, you can achieve a cleaner vocal or, conversely, add "warmness" to the sound.
| The regime (Preset) | Characteristics | What's the point? |
|---|---|---|
| By default. | Equal distribution | Podcasts, audiobooks |
| Rock. | Focus on the medium frequencies | Guitar music, metal |
| pop | Raised high and low | Modern pop-stage |
| Bass-booster | Maximum low frequencies | Electronic music, hip-hop |
⚠️ Note: When manually adjusting the equalizer, avoid lifting sliders to the extreme upper position, as this can cause digital distortion (clipping) and make the sound unpleasant.
Remember that the equalizer settings apply globally to all audio played through the media channel, which means that the profile you choose will be active on YouTube, Spotify, and when watching movies in your local player.
💡
A properly selected equalizer preset can compensate for the disadvantages of cheap headphones, making the sound more balanced and pleasant.
Dolby Atmos and Mi Sound Enhancer
One of the most talked-about features in Xiaomi devices is Dolby Atmos. This system creates a surround sound effect, processing audio so that it appears to be coming from all sides, including height. On smartphones, this is implemented software, and the effectiveness depends on the quality of the implementation of the speakers and algorithms of a particular model.
In the settings menu Dolby Atmos on Xiaomi usually offers several modes: "Automatically", "Video", "Music" and "Voice". The mode "Automatically" tries to determine the type of content and apply the appropriate profile, but often manual switching gives a more predictable result. For example, to watch movies in the theater, you better choose the mode "Video", which expands the sound scene.
In parallel with Dolby, the Mi Sound Enhancer is designed to compensate for the frequency losses of cheap headphones. The algorithm analyzes the connected device and tries to align the frequency response, but many audiophiles prefer to turn off this feature, believing that it introduces artifacts and makes the sound “plastic”.
- 🎬 Video Mode: Expands stereo by making explosions and background noises more voluminous.
- 🎤 Voice mode: Highlights the average frequencies, making the speech of announcers and actors more legible.
- 🎼 Music Mode: Balances the sound, trying to preserve the author's idea of the mix.
It’s worth noting that activating Dolby Atmos can increase the power consumption of the device, albeit slightly.If you’re listening to music through regular wired headphones without claiming the audiophile level, it might make sense to experiment with turning off surround sound in favor of pure stereo.

Customization of sound for headphones and Bluetooth
Special attention should be paid to the settings section, which is activated only when you connect the headset. Once you insert the headphone plug or connect a Bluetooth device, additional options appear in the audio menu, this is due to the fact that the smartphone goes into operation with an external DAC (digital-to-analog converter) or transmits a signal over a digital channel.
This section often includes the "Mi Sound Enhancer for headphones" feature, which has its own presets for different types of headphones (intrachannel, overhead), and you can also adjust the smartphone's response to pressing buttons on the headphone wire: switching tracks, answering a call or activating a voice assistant.
For Bluetooth devices, the data codec is critical. In the engineering menu or through special applications (for example, Bluetooth Codec Changer, which requires root rights, or through hidden developer settings), you can select a priority codec.
Settings → About phone → 7 times press on "Version MIUI" → Settings → Additional settings → For developers → Bluetooth codec (AAC, aptX, LDAC)Using an LDAC or aptX HD codec allows you to transmit sound in much higher resolution than a standard SBC. However, for this, both the headphones and the smartphone must support the chosen standard. If support is available, be sure to switch the codec in the developer settings to get the maximum wireless sound quality.
⚠️ Switching to high-quality Bluetooth codecs (LDAC, aptX HD) It can cause unstable connections in places with a lot of radio interference, as well as increase the latency of sound in games.
Advanced settings through the engineering menu
For users who are not afraid to go deep into the system settings, there is an engineering menu, which is a hidden section of the interface, designed for testing equipment by engineers in the factory, but accessible to ordinary people, and you can find options that are not in the standard menu, such as fine-tuning the gain levels of the microphone or speakers.
The engineering menu is logged in via a special code set in the Phone app. For most Xiaomi devices, it is code ##6484## (CIT test menu) or ##3646633# (MediaTek engineering menu, found on old and budget models). On Qualcomm processors, access to audio tests is often limited or requires special ADB rights.
Inside the menu, you'll find the Hardware Testing → Audio → Audio Debug tab, which lists devices (Speaker, Receiver, Headset) and modes (Playback, Record), and by changing the Gain values (amplification), you can force the sound to be louder than the system constraints, but it's a risky operation.
- 🔧 Audio Type: Selection of device type (dynamics, headphones, headset).
- 📢 Level: Volume level (from 0 to maximum).
- 📈 Gain: Signal amplification coefficient (modify with extreme caution!).
The main risk when working with the engineering menu is the possibility of damaging the speaker by software, sending a signal to it too powerful, or knocking the calibration so that the sound will become quiet even after reset. Changing the Gain parameters in the engineering menu can lead to irreversible burnout of the speaker if you exceed the permissible amplitude values.
