How to set up the equalizer on Xiaomi 12: from bass to Hi-Fi sound

Xiaomi 12 is equipped with an advanced audio system with support for 24-bit sound and stereo speakers, but by default the sound often leaves much to be desired. Bass can be dirty, high frequencies can be too sharp, and the voice of the vocalist is “scored” instruments. MIUI hidden powerful equalizer, which allows you to fine-tune the sound to your headphones, musical preferences or even the acoustics of the room.

In this article you will find not only basic instructions for including the equalizer, but also exclusive presets for different genres of music (from hip-hop to classics), tips for customization for specific models of headphones (Xiaomi Buds 4 Pro, Sony). WH-1000XM5 etc., and we will also discuss how to circumvent the restrictions MIUI If you ever thought the sound on Xiaomi 12 could be better, this article is for you.

Before you start, make sure that your device has the latest version installed. MIUI (lower 13.0.5 Xiaomi 12/12 Pro/12 In older versions, the equalizer interface may be different and some features (e.g. adaptive sound) may not be available.

Where is the equalizer on Xiaomi 12 and how to turn it on

Unlike many Android smartphones, where the equalizer is hidden in the sound settings, the MIUI It can hide, depending on the firmware version and the region. Here are three official ways to find it:

• 🎵 Through the sound settings: go to Settings → Sound and vibration → Sound quality → If you don't have the "Sound Quality" item, try the following method.
• 🎧 From the control panel: swipe down from the top edge of the screen to open the notification bar, then press and hold the Sound icon (Speaker) – a menu with quick equalizer access will open.
• 🔍 Through the Music app: Open the standard Mi Music player, play the track, click on the three dots in the top right corner and select the Equalizer.

If the equalizer is not present in all the specified locations, this may mean that:

1. There is a global version installed on your device. MIUI without audio feature (for example, MIUI In this case, the equalizer is often disabled for licensing reasons.
2. There was a breakdown in work. MIUI Sound Enhancer, the system module that handles sound processing, is solved by rebooting or resetting the sound settings.

⚠️ Note: Xiaomi 12 Ultra with firmware MIUI 14+ The equalizer can be replaced with Dolby Atmos. To return the classic equalizer, disable Dolby in Settings. → Sound. → Dolby Atmos → Off..

💡

If the equalizer does not appear, try changing the region of the device to India or China in the settings Additional → This often unlocks hidden audio features.

Basic settings of the equalizer: what do sliders and presets mean

The equalizer in Xiaomi 12 offers 10 adjustment bands (60 Hz to 16 kHz) and 8 presets. Let's understand what each frequency is responsible for and how to set it correctly:

Ready presets in MIUI Optimized for specific genres, but often require improvement:

• 🎸 Rock: 250Hz (drums) and 3kHz (guitar) reinforced, but weak bass - add +3 dB at 80 Hz.
• 🎤 Vocals: raises 1-2 kHz, but can make the sound “irritated” – lower 500 Hz by -2 dB.
• 🎧 Headphones: universal preset, but often over-enhanced high frequencies – reduce 10–16 kHz by –1 dB.

Important: On the Xiaomi 12 Pro with Harman Kardon speakers, the Classic has a nonlinear curve by default - the 1kHz slider is shifted left by -3 dB, which creates a "distant" sound effect. Correct this manually for natural sound.

Advanced settings: adaptive sound, Dolby Atmos and hidden features

In addition to the standard equalizer, the Xiaomi 12 supports several hidden audio technologies that can be activated through an engineering menu or third-party applications.

Adaptive Sound (Adaptive Sound)

The function automatically adjusts the equalizer to the acoustics of the room and the type of headphones.

1. Go to Settings → Special features → Sound improvements.
2. Activate the Adaptive Sound Switch.
3. Select the profile: Headphones, Speakers or Auto.

It uses machine learning to analyze the reflected sound waves, and the effect is only noticeable in quiet rooms, where the algorithm shuts down in noisy conditions.

2. Dolby Atmos (only for Xiaomi) 12 Pro/Ultra)

Dolby Atmos creates surround sound, but by default it only works with the smartphone's speakers to make it work with headphones:

Install Dolby Access from Google Play|Go to Settings. → Sound. → Dolby Atmos|Choose a profile of Movies or Music|Enable the option Headphones in additional settings-->

Note that Dolby Atmos conflicts with the standard equalizer. When Dolby is activated, all manual equalizer settings are reset.

3. Hidden menu of audio settings (Engineering Mode)

For power users, you can set up a hardware amplifier, an earphone impedance, and even calibrate the microphone to get there.

1. Open the Phone app.


2 Enter the code ##36446337##




3. Go to the Hardware Testing → Audio section.

⚠️ Attention: Incorrect settings in the engineering menu can damage the speakers or headphones. Change only the settings you are sure of. For example, increasing the Headset Amp Gain value above 50% risks burning the headphone membranes.

Optimal settings equalizer for different headphones

The sound is heavily influenced by the impedance and frequency characteristics of your headphones. Below are the verified settings for popular models tested on Xiaomi 12:

1. Xiaomi Buds 4 Pro (and others) TWS-Xiaomi headphones)

By default, the Buds 4 Pro have excessive high frequencies and weak basses.

• 60 Hz: +4 dB (reinforce subbass)
• 250 Hz: +2 dB (add heat)
• 1 kHz: 0 dB (leave unchanged)
• 3 kHz: -1 dB (remove "metallicity")
• 10 kHz: -2 dB (to smooth out peaks)

For the Buds. 3/3T Pro reduce 60 Hz +2 dB – their speakers are smaller and can not cope with deep bass.

2. Sony WH-1000XM5 (and other full-size headphones)

Sony WH-1000XM5 They have their own sound processing (DSEE Extreme, but Xiaomi 12 equalizer could further improve detail:

• 80 Hz: +1 dB (bass is good, we don't overload)
• 500 Hz: -1 dB (remove the “dirty” in the middle)
• 2 kHz: +1 dB (emphasize vocals)
• 12 kHz: +2 dB (add “air»)

If you use LDAC (high-resolution codecs), disable all processing in the headphone settings - let the equalizer control the smartphone.

3. wired headphones (3.5 mm or Type-C)

For wired headphones with impedance 16-32 ohms (most smartphone models) suitable universal setting:

• 100 Hz: +3 dB
• 1 kHz: 0 dB
• 6 kHz: +1 dB
• Other sliders: 0 dB

For headphones with impedance >100 Ohms (e.g. Beyerdynamic) DT 770 Pro) increase the overall volume by 10-15% – the Xiaomi 12 hardware amplifier poorly copes with high-omnipotent load.

💡

For headphones with open acoustics (for example, Sennheiser) HD 600) reduce bass by -2 dB at 60-150 Hz frequencies – this compensates for the effect of the “bass boost” due to the leakage of sound.

How to save equalizer settings and apply them to all applications

One of the main problems of the equalizer in MIUI — It resets when you plug in new headphones or when you reboot it, to avoid that:

1. Save the preset: In the equalizer menu, click on the three dots in the top right corner and select Save as Custom. Assign a name (e.g., "My Headphones").
2. Link to the profile: in Settings → Sound. → Sound quality select Apply to all apps. This will make the equalizer work even in YouTube, Spotify and games.
3. Use third-party apps: If the standard equalizer doesn’t save settings, install Wavelet or Poweramp Equalizer from Google Play. They offer more flexible settings and auto-switch profiles.

Apps that ignore the system equalizer (such as Netflix or Tidal) will require root access or use of the Audio Modification Library (AML). The latter allows you to “implement” the equalizer at the system level, but requires unlocking the bootloader.

⚠️ Attention: When in use ViPER4Android (A popular modified equalizer on Xiaomi 12 Android 13+ There may be a conflict with MIUI Sound Enhancer, which causes high volume audio distortion. Solution: Turn off. MIUI Sound Effects via Sound Effects ADB: adb shell settings put global miui_sound_effect_enabled 0

Common Problems and Their Solutions

Even after setting the equalizer correctly, Xiaomi 12 users face typical problems.

If after all the manipulations the sound remains unsatisfactory, check:

• 🔊 Quality of audio files: MP3 With a bitrate of 128 kbps, it won't unlock the equalizer potential. FLAC or WAV.
• 🎛️ Bluetooth Codecs: Choose for wireless headphones LDAC or AAC In Settings → Bluetooth → Sound settings.
• 🔋 Performance mode: c Settings → Battery → Select Performance Modes – This Disables Limits on Sound Processing.
