Deep adjustment of sound balance in Xiaomi smartphones

Users of Xiaomi’s flagship and budget models often face a situation where the standard sound of speakers or headphones seems flat and lacking in depth. The standard settings of MIUI or the new HyperOS shell offer basic presets that do not always take into account individual hearing preferences or the specifics of the acoustics used.

The concept of sound balance in the context of the Xiaomi ecosystem covers not only the volume ratio of the left and right channel, but also the complex operation of the digital signal processor (DSP). Competent configuration allows you to compensate for the shortcomings of budget speakers or, conversely, to enhance the detail of the top models of the Xiaomi 13 and 14 series. In this guide, we will discuss how to turn mediocre sound into a quality audiophile experience without the use of third-party equipment.

It is worth noting that improper setting can lead to distortion or even damage to the speaker at extreme values. The critical threshold is considered to be the increase in frequencies above +6 dB in the standard equalizer, which can cause clipping (digital overflow) of the signal.

Interface of the Xiaomi equalizer

In most of the brand's modern smartphones, access to audio settings is hidden in the media menu. To get there, you need to go through the Settings → Sound and Vibration → Sound settings → Sound Effects. Here, the user finds a graphical interface consisting of sliders, each of which is responsible for a certain frequency range. Usually it is a 10-band equalizer covering the entire audible spectrum.

The interface is divided into three main zones: low frequencies (bass), medium frequencies (voice, basic instruments) and high frequencies (parts, air). By manipulating sliders, you create a unique response curve. It's important to understand that visualization on the screen does not always accurately reflect what you hear, so rely solely on auditory perception.

At the bottom of the screen are often presets like Pop, Rock, Jazz or Normal, which are predefined profiles by Xiaomi engineers' algorithms. However, to achieve perfect sound balance, it is recommended to start with a profile like Normal or User to have a clean starting point.

• 🎚️ Sliders allow you to change the volume of a particular frequency in the range of -12 before +12 dB.
• 🎧 The headphone button activates the compensation mode if an external audio device is connected.
• 🔊 The overload indicator lights up red if the total volume is too high.

⚠️ Warning: Long-term listening to music with amplified low frequencies at maximum volume can lead to mechanical damage to the speaker membrane.

Frequency range adjustment

To achieve balanced sound, you need to understand the physics of wave propagation in each band. Low frequencies (20 Hz – 250 Hz) are responsible for power and volume. In Redmi and Poco smartphones, this range is often clamped down due to the small size of the case, so its light lifting can add to the desired density.

The average frequencies (250 Hz – 4 kHz) are the foundation of most musical compositions, and there is the vocals and rhythm section, and the over-lifting of these sliders makes the sound screaming and tiring, and under-reporting it deaf and distant, and the perfect balance in this sector ensures the naturalness of the sound.

High frequencies (4kHz – 20kHz) add transparency and detail to the track, which allows you to distinguish between string ringing or rustling plates, but in budget models such as the Redmi Note series, this range can sound sharp or "sand." Careful correction can remove this unpleasant sound.

By experimenting with settings, you can create multiple profiles for different genres. MIUI allows you to save custom settings, which eliminates the need to manually reconfigure sliders every time.

Spatial audio and virtualization

Xiaomi’s current flagships feature virtual surround sound technologies like Dolby Atmos or the company’s own designs, which attempt to simulate multi-channel sound through a stereo pair of speakers, and enable this option to greatly expand the sound scene.

When spatial audio is activated, the sound stops being inside the head (as in conventional headphones) and spreads around the listener, especially when watching movies or games, where it is important to understand the direction of steps or shots, but for music, this mode can be redundant and contribute artifacts.

Consider that the inclusion of spatial sound effects increases the load on the processor and, as a result, the battery consumption. In the Xiaomi 13 Ultra and 14 Pro models, this optimization is done perfectly, but on older devices, there can be a slight delay in audio.

Specifics of settings for headphones

When wired or Bluetooth headphones are connected, a separate switch appears in the effects menu. Xiaomi algorithms try to automatically determine (impedance) the connected acoustics and adjust the output power. For cheap headphones, this works well, but for audiophile models, you may need manual.

Often users forget that the equalizer settings for speakers and headphones can vary or reset when switching. Check if the "Separate setting" item in the audio menu is active, which will save the profile for external acoustics without breaking the main speaker setting.

If you use high-quality wired headphones with high resistance, the built-in smartphone amplifier may not be enough, in which case the software frequency correction will not give the expected result, since there is not enough physical power to rock the dynamic heads.

• 🔌 For wired headphones available Mi Sound mode, improving detail.
• 🎼 Bluetooth codecs (LDAC, aptX) affects quality more than equalizer settings.
• 📉 When connecting the headset, the noise reduction of the microphone is automatically turned on.

⚠️ Note: When using an adapter USB-C 3.5mm Some audio processing software features may not be available due to Android driver limitations.

Addressing Channel Imbalance

One of the common problems is when the sound from one speaker is quieter than from another, or disappears completely in one headphone channel. Before you blame (hardware), it is worth checking the system availability settings. Android has a feature called Mono-audio that mixes the channels, but it does not solve the problem of volume difference.

To diagnose, run the test track from audiocheck.net through your browser. Go through the frequencies and listen to if there is a skew. If there is an imbalance in only one application (for example, only in Telegram), the problem is in the codec or settings of the application itself, not the system.

In rare cases, resetting the sound settings to the factory helps. → Sound and vibration need to find the reset button (if available in your version of HyperOS) or simply return all sliders to zero position".

Third-party solutions for advanced users

Staffing is sometimes not enough to fine-tune, and enthusiasts often turn to applications like Poweramp Equalizer or Wavelet, which run on top of the system's audio stream and offer more accurate tools, including a parametric equalizer.

These apps on newer versions of Android (13, 14) often require special permissions or run through adb.

adb shell pm grant com.pawxy.powerampequalizer android.permission.READ_LOGS

Using third-party software can lead to conflicts with the system Dolby Atmos. It is recommended to disable the built-in effects of Xiaomi when using external equalizers to avoid double signal processing and the occurrence of "porridge" in the sound.

💡

Tip: Before installing a third-party equalizer, take a screenshot of the current settings of the standard equalizer so that you can quickly return to the original values.

💡

Third-party equalizers give more control, but require disabling system enhancements to avoid conflict.
