How to change the color of the sound on Xiaomi Poco X3: audio-tuning MIUI

Have you ever wondered why your Xiaomi Poco music is so popular? X3 It's not just about the speakers -- the right setup of the audio profile can change the way you hear audio, and the term "color of sound" isn't about the real color, it's about the timbral color: warm bass, transparent tops, or balanced midrage. In this article, we will analyze all the ways of customizing sound on Poco. X3 — From standard equalizer to hidden functions MIUI.

Xiaomi Poco Smartphone X3 (model M2007J20CG) It's equipped with Dolby Atmos stereo speakers, but not all features are activated by default, and many users don't even realize that the system has advanced audio settings, which are available through an engineering menu or third-party applications. We will show legal and safe methods that do not require root rights and do not violate the guarantee.

What is the color of sound and why is it important?

In audio, "color of sound" (or timbre) defines unique tone characteristics that distinguish, for example, a guitar from a piano even at the same note height.

• 🎛️ Equator - adjustment of frequency ranges (bass, mides, tops)
• 🎧 Sound effects – reverb, spatial sound (Dolby, DTS)
• 🔊 Hardware profiles – optimization for headphones, speakers or Bluetooth devices
• 🎚️ Loud curves – nonlinear volume control for different levels

On Poco. X3 factory settings are often focused on the “average” user, which leads to the:

• ❌ Dirty bass when listening through speakers (especially at high volume)
• ❌ Muffled vocals in tracks with tight mixing
• ❌ Sharp tops in headphones with sensitive drivers

You can fix this without buying a new device - it is enough to correctly configure existing tools. MIUI 12/13/14.

Standard sound settings in MIUI: What can be changed without third-party applications

Start with the basic tools that are available out of the box. Go to Settings. → Sound and vibration. There are three key sections for you:

1. Equalizer (Sound Effects) → Equalizer) – 5-band graphics regulator with presets (Rock, Pop, Jazz, Classic, etc.).
2. Dolby Atmos (Sound Effects) → Dolby – spatial sound with profiles Film, Music, Voice, Game.
3. Adaptive sound (sound effects) → Adaptive sound) – automatic adjustment to the type of headphones.

An important nuance: equalizer settings are applied separately for speakers and headphones. If you connect a Bluetooth device, the profile will be reset to a standard one. To avoid this, use device-specific profile binding (more on this below).

The critical feature of Poco X3: When Dolby Atmos is activated, the system equalizer automatically shuts down, which means you can't combine both effects at the same time, the solution is to use third-party applications (section 4) or an engineering menu (section 5).

💡

After the update MIUI Dolby Settings are missing, go to Settings → Annexes → Application management → Three points. → Show system-based → Dolby and clear the cache.

Step-by-step setting up the equalizer for different genres of music

There is no universal recipe - the perfect settings depend on your headphones and preferences. We have collected proven presets for popular genres that can be used as a basis:

🎸 For rock and metal.

• 🔹 60 Hz (bass): +4 dB
• 🔹 230 Hz (lower mides): +2 dB
• 🔹 910 Hz (medium midds): 0 dB
• 🔹 3.6 kHz (top): +1 dB
• 🔹 14 kHz (topmost): +3 dB

Why: Enhanced bass adds weight to guitars and drums, and a 14kHz rise makes vocals and lead guitars more distinct.

🎤 For vocal music (pop, R&B)

• 🔹 60 Hz: +2 dB
• 🔹 230 Hz: -1 dB
• 🔹 910 Hz: +3 dB
• 🔹 3.6 kHz: +2 dB
• 🔹 14 kHz: 0 dB

The secret: a decrease of 230 Hz removes the “dirty” in the voice, and a rise of 910 Hz makes the vocals more present.

🎻 For classical music

• 🔹 All sliders in 0 dB (flat ACH)
• 🔹 Activate Dolby Atmos in Music Mode

Classics are recorded with perfect balance, so it is better not to interfere with the frequency response, but to focus on the spatial sound.

Make sure your headphones are connected (if you set them up for them)|

Check the volume at the level 50-70%|

Play the test track (recommended for "Bohemian Rhapsody" or "Hotel California")|

Compare it to the factory preset "Platsky"|

Keep a profile with a unique name (e.g. Rock_HD600")-->

Dolby Atmos at Poco X3: How to turn on and set up

Dolby Atmos at Poco X3 It only works with wired headphones or speakers – Bluetooth requires support for aptX codec HD or LDAC, That the phone doesn't support out of the box, to activate the effect:

1. Go to Settings. → Sound and vibration → Sound effects → Dolby.
2. Select a profile: 🎬 The film is a reinforced environment for the cinema 🎵 Music - Extended Stage for Tracks 🎮 Playing – Emphasis on Sound Effects 🗣️ Voice - Suppressing Noise for Podcasts

Additionally.

• 🔄 Virtualizer - the width of the stereobase (recommended) 70-80%)
• 🎛️ Graphic equalizer - there are only 3 stripes (bottoms, mides, tops)
• 🔇 Volume Limiter – Better to Turn Off for Music

Problem: When you activate Dolby, the system equalizer in the Sound Effects section is turned off. MIUI, but it can be bypassed:

⚠️ Warning: If the sound is quieter after Dolby activation, check the Safe Volume settings in Settings → Sound. → This mode automatically limits the signal level when the headphones are detected.

Hidden audio settings via engineering menu (no root)

Engineering menu MIUI It allows you to fine-tune the audio subsystem, including:

• 🔧 Reinforcement of the microphone for calls
• 🎚️ Correction of the frequency of the speakers (compensation of peaks / failures)
• 🔊 Volume setting for each type of notification
• 🎛️ Activation of hidden audio profiles (e.g. Hi-Fi Mode)

To open the menu:

1. Open the Phone app.
2. Enter the combination: ##36446337##
3. Choose Hardware Testing → Audio.

In the Audio section, please note:

• 🔹 Headset Mode – Headphone testing (checks resistance and frequency characteristics)
• 🔹 Speaker Mode – speaker calibration (useful if the sound is “hrizzing” at maximum)
• 🔹 Mic Test - adjusting the sensitivity of the microphone
• 🔹 Loopback Test – Checking the sound circuit (for fault diagnosis)

⚠️ Warning: Do not change the settings in Register or Codecs subsections without understanding the consequences. Incorrect values can lead to complete sound loss, which is corrected only by resetting to factory settings.

Hidden chip: In the engineering menu, you can activate Hi-Fi Mode, which disables all post-processing audio (including Dolby) for a clean signal.

1. Go to Audio. → Music.
2. Find the HiFi Mode option and set the value 1.
3. Reboot the phone.

This mode is useful for listening to music in the format FLAC or WAV high-headed.

Third-party applications for advanced sound tuning

If the standard instruments MIUI Not enough, consider these apps (all tested for Poco compatibility) X3):

Important note: Appendices like ViPER4Android Or JamesDSP requires Magisk to work properly, and without root, they'll only work with individual players (like Poweramp:

1. Download Magisk Module for the selected application.
2. Install it through Magisk Manager.
3. Reboot the phone.
4. In the application settings, select System-wide audio processing.

Wavelet or Poweramp root are not required, they work at the application level, but can conflict with the system Dolby. With the simultaneous use of several sound modifiers, artifacts (wheezing, stuttering) or complete loss of sound are possible.

💡

If the sound is gone after installing the third-party equalizer, clear the cache of the Android System WebView application in the settings. This solves 90% of problems with audio driver conflicts.

Customizing the sound for specific headphones: how to tie a profile

One of the most underrated tools MIUI — And you can attach audio profiles to specific devices, and you can automatically switch settings when you connect your headphones, speakers, or car tapes to adjust:

1. Connect headphones (wired or Bluetooth).
2. Go to Settings. → Sound and vibration → Sound effects → equalizer.
3. Set the desired settings (or select a preset).
4. Click on the three dots in the top right corner and select Save as a profile.
5. Enter the name (e.g. Sony) WH-1000XM4 Bass.+).
6. Activate the option to apply automatically when connected.

How it works: The system remembers MAC-Bluetooth device address or connection type (3.5mm jack) and uses the saved profile. For speakers, the phone uses geolocation: if you often listen to music in the same room, MIUI You may want to create a profile for this place.

Limitations:

• ❌ For Bluetooth devices, the profile is only used when you first connect after a reboot.
• ❌ If the headphones support multiple codecs (for example, SBC and AAC), Profile can be reset when changing the codec.
• ❌ Maximum 5 saved profiles.

To remove unnecessary profile, go to Settings → Annexes → Application management → Three points. → Show system-based → SoundAssistant and clean up the data.

Diagnosing Sound Problems After Changes

If you have problems after experiments with sound, use this instruction to diagnose:

1. Check the basic settings: 🔊 Make sure the sound is not turned off by the volume buttons. 🔕 Check if the Do Not Disturb or No Sound mode is activated. 🎧 Connect other headphones – the problem may be in them.
2. Reset the sound settings: Go to Settings → System system → Resetting settings → Resetting the sound settings, which will bring all the equaliser and Dolby parameters back to the factory.
3. Check Application Conflicts: Disable all third-party equalizers in Settings → Apps. Clear the Android System WebView cache and Media Storage.

Testing through the Engineering Menu:

• Open the engineering menu (code ##36446337##)
• Choose Audio. → Speaker Test and check both speakers.
• If one speaker does not work, the problem is in the hardware.

Common mistakes and decisions:

⚠️ Warning: If after all the manipulations the sound in the headphones remains quiet, check the resistance of your headphones. X3 Optimized for headphones with impedance 16-32 Om, headphones with resistance 250+ Ohm (e.g. Beyerdynamic) DT 990 Pro) will sound quiet without an external amplifier.
