Xiaomiโs technology is famous not only for its affordable price tag, but also for advanced features that often go unnoticed, such as audio optimization, which can dramatically improve the perception of music, movies and games, but many users are unaware of its existence or do not know how to activate it correctly.
In this article, we will discuss all ways to enable sound optimization on Xiaomi devices โ from Redmi smartphones and other devices. POCO before Mi TVs TV. You'll learn what modes are available, how they affect sound, and why standard settings are often lost by customized ones, and then you'll discover a secret parameter in the engineering menu that the manufacturer doesn't advertise.
What is Sound Optimization and Why You Need It
Sound optimization is a software-based audio processing that adjusts frequency, balance and spatial sound for a particular device, and Xiaomi's technology is implemented through:
- ๐ Equator โ manual frequency setting (low, medium, high)
- ๐ต Presets of sound โ ready profiles for music, movies, games
- ๐ง Adaptive sound - automatic adjustment to the acoustics of the room
- ๐ง Optimization for headphones โ improving sound when connecting the headset
Without optimization, sound can seem flat, especially on budget models with a single speaker. For example, on the Redmi Note 12, bass is often booed and high frequencies are lost.
- ๐ Strengthen bass without distortion
- ๐ถ Make vocals clearer in music
- ๐ฌ Improve the clarity of dialogue in films
- ๐ฎ Add volumes to the sounds in games
Itโs important to understand that optimization wonโt make a budget smartphone a Hi-Fi system, but smart settings can bring sound closer to premium devices. For example, on the Mi 11 Ultra with two speakers, the correct calibration gives the effect of surround sound.
How to enable sound optimization on Xiaomi smartphones
On most Xiaomi smartphones, including Redmi, POCO And Mi, the audio optimization is hidden in the sound and vibration settings. Here's the step-by-step instruction:
- Open the Settings. โ Sound and vibration
- Tap on Sound Quality (or Sound Effects on Older Versions) MIUI)
- Activate the Sound Optimization Switch (also known as Mi Sound Enhancer)
- Choose one of the presets: ๐ต Music โ High and medium frequencies are enhanced ๐ฌ The film - an emphasis on dialogue and bass ๐ฎ Play is a spatial sound ๐ Auto โ adaptive setting for content
In some models (for example, POCO F5) You can manually adjust the equalizer:
- In the same menu, select the Equator
- Move the sliders to adjust the frequencies: 60Hz - ultra-low bass 230Hz - lower mid 910Hz - medium frequencies 3.6kHz - presence (vocals) 14kHz - air (overtones)
Keep the presit under your name.
โ๏ธ Audio optimization check
For devices with Dolby Atmos (such as Xiaomi 13 Pro), the algorithm is different:
- Go to Settings. โ Additionally. โ Dolby Atmos
- Select a profile: Music, Film or Voice
- Activate Adaptive Sound for Automatic Adjustment
To get into the engineering menu:
- Open the phone application
- Enter the code ##36446337##
- Go to the Hardware Testing section โ Audio
Inside you will find the parameters:
| Parameter | Default value | Recommended value | The effect |
|---|---|---|---|
| Speaker Gain | 0 dB | +2...+4 dB | Increase in overall volume |
| Headset Gain | 0 dB | +1...+3 dB | Amplifiing the sound in the headphones |
| Bass Boost | Off | Low/Medium | Low frequency amplification |
| Loudness | Off | On | Volume compensation at low levels |
โ ๏ธ Note: Changes to Speaker Gain settings above +6 dB can cause sound distortion and overheating of speakers.On single-speaker models (Redmi) 9A) risk particularly high.
What happens if you reset the engineering menu settings?
For the application of the changes:
- Press Set next to each modified setting
- Reset the device
- Check the sound on different types of content
Optimizing the sound on Mi TVs TV
Xiaomi Mi TVs TV (Especially the Dolby Audio models have advanced audio settings that are often ignored:
- On the remote, press Menu. โ Settings โ Sound.
- Select Sound Mode and set it: ๐ฌ Film - for a movie with surround sound ๐ต Music - for concert recordings ๐ฃ๏ธ News for clarity of speech ๐ฎ The game is for a dynamic sound
Dolby Audio
Auto-volume setting
For models with soundbar (e.g. Mi) TV Q2 75) room calibration available:
- Go to Settings. โ Sound. โ Acoustic adjustment
- Follow the voice instructions โ the TV will give test signals
- Microphone in the remote analyzes the reflection of sound from the walls
- Through 2-3 A personal profile will be created in minutes.
๐ก
If after setting the sound became worse, reset the sound settings to factory: โ Sound. โ Resetting the audio settings. This often helps with the "hang" of audio drivers.
Optimization for headphones and Bluetooth devices
When you connect your headphones or Bluetooth speakers, Xiaomi automatically switches to an optimized profile, but you can customize it:
For wired headphones:
- Put the headphones on.
- Go to Settings. โ Sound. โ Sound quality in headphones
- Choose the type of headphones: ๐ง Inlays - increasing the average frequencies ๐ง Overhead - balance of bass and top ๐ง Full-size - extended bass
LDAC
For Bluetooth devices:
- Connect the device.
- In Bluetooth settings, tap on the icon โ๏ธ near-device
- Choose Sound Quality โ High (may be called AptX or AptX) AAC)
- Turn off the absolute volume for independent adjustment
On models with Mi Super Audio (e.g. Xiaomi) 12S Ultra) spatial audio available for headphones:
- Activate Settings โ Special facilities โ Sound. โ Spatial audio
- Select Headphones as the output device
- Adjust the intensity of the effect (recommended) 50-70%)
โ ๏ธ Note: When using cheap Bluetooth speakers, enable AptX codecs or LDAC This could lead to cod, in which case you switch to standard. SBC.
Common Problems and Their Solutions
Even after optimizing, users face problems, and here are the most common ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The sound is quieter after optimisation | Volume limiter activated in EU-firmware | Change region to India in phone settings |
| Distortion at maximum volume | Speaker Gain is too high on the engineering menu | Set the value no higher. +4 dB |
| Dolby Atmos Prestos is not working | There is no license on the device | Update the firmware to the latest version |
| The sound in mono headphones | Contaminated connector 3.5 mm | Clean the connector with alcohol and cotton. |
If the sound has disappeared completely after the setting:
- Check if the mode is activated Do not disturb
- Reset the device
- Reset the sound settings: Settings โ System โ Resetting the settings โ Resetting the sound settings
- If the problem remains - perform reset to factory settings
On Mi TVs. TV frequent problem - delay of sound when connecting through HDMI ARC. That's how it works:
- Turn off Dolby Sound Processing in TV settings
- Set the sound format: PCM auto
- Update the TV firmware and sound bar
Comparison of sound before and after optimization
To assess the real effect of optimization, conduct a test:
- Include a track with a wide dynamic range (e.g., "Bohemian Rhapsody")
- Listen for 30 seconds with standard settings
- Activate the optimization and listen to the same snippet.
- Pay attention to this: ๐ The clarity of basses (whether they are "drumping?) ๐ค Legacy of vocals ๐ถ Spatial sound (the effect of "volume") ๐ No distortion at high volume
For objective evaluation, use test audio files:
- ๐ AudioCheck โ frequency swipes and stereo tests
- ๐ต SoundGuys โ tracks to check the dynamics
On Mi TVs. TV For the test, use the built-in Dolby Demo video:
- Open the Apps โ Dolby Access
- Select Demo Content
- Compare sound to on and off optimization

Sound optimization has the greatest impact on mid-range speakers, on budget models with a single speaker (e.g. Redmi). 9C) Improvements will be minimal โ consider buying an external column.
