Xiaomi's wireless headphones are not just about freedom of movement, but also about being able to immerse yourself in sound as comfortably as possible. But many users face the problem: when you connect AirDots, Buds or other models, the sound becomes flat, lacking volume and depth. The reason is often due to the default sound effects in MIUI firmware. In this article, we'll look at how to activate the equalizer, spatial sound and other functions so that your music will play with new colors.
It is important to understand that the audio settings on Xiaomi depend on three factors: the MIUI version (12/13/14/15), the smartphone model (for example, the Redmi Note 12 Pro+ or POCO F5) and the type of wireless headphones. Some effects are only available for Xiaomi branded devices (for example, FlipBuds Pro), but most universal settings work with headphones of other brands โ Sony WH-1000XM5 or Apple AirPods.
If you've never looked at the audio settings, prepare to be surprised. Even Redmi's budget models support 5-band equalizer, presets for different genres of music, and even surround sound imitation. And flagship owners (such as Xiaomi 14 Ultra) get access to Mi Sound Enhancer technology, which adapts the sound to the anatomy of the user's ear.
1. Basic sound settings in MIUI: where to look?
The first thing you need to do is open the main audio menu, and the path to that may vary slightly depending on the firmware version, but the general outline is this:
- Open the Settings app (the gear icon on the home screen).
- Go to Sound and Vibration (some versions simply Sound).
- Scroll down to the Sound Quality or Sound Effects block.
On the screen you will see a few key options:
- ๐ต Equalizer - manual frequency setting or ready presets (for example, "Rock", "Pop", "Classic").
- ๐ Sound amplifier โ increases volume by compressing (useful for quiet tracks).
- ๐ง The effects on headphones are spatial sound, bass, and other enhancements.
- ๐ Adaptive sound is an automatic environment adjustment (not available on all models).
If you have Xiaomi with MIUI 14+, the same section might include the Mi Sound Lab, which is a proprietary sound lab where you can test experimental effects, for example, there's a Super Bass option that amplifies low frequencies without distortion.
2. How to turn on the equalizer for wireless headphones
The EQ is the primary tool for customizing the sound to your preferences, and in MIUI, it's hidden deeper than you might think. Here's the exact instructions:
- Go to Settings โ Sound and vibration โ Sound quality โ Equalizer.
- Activate the switch at the top of the screen (if it is turned off).
- Select one of the presets or click User to adjust the frequencies manually.
For wireless headphones, we recommend starting with Basa or Rock preset, and then adjusting the sliders:
- ๐น 60Hz - Responsible for heavy bass (increase for electronic music).
- ๐น 230Hz are medium basses (important for vocals and acoustic instruments).
- ๐น 910 Hz is the lower middle (reduce if the voice sounds "deaf").
- ๐น 3.6 kHz is the upper middle (responsible for the "presence" of sound).
- ๐น 14 kHz - High frequencies (increase for "air" in tracks).
Important: Equalizer settings in MIUI apply to all connected audio output devices, including the smartphone speaker. If you want separate headphone settings and speakers, use third-party apps like Wavelet or Poweramp.

3. Include spatial sound (3D-audio) on Xiaomi
Spatial audio (or 3D-audio) creates the illusion of surround sound, as if the source is around you, not inside the head. On Xiaomi, this feature is called Mi Spatial Audio and works only with branded headphones (FlipBuds Pro, Buds 4 Pro, etc.). For other models, you can enable emulation through settings.
Instructions for activation:
- Connect the headphones to your smartphone.
- Go to Settings โ Sound and vibration โ Sound effects for headphones.
- Select the option Spatial Sound or 3D-audio.
- Activate the switch and select the intensity level (e.g., "Weak", "Mediocre", "Strong").
If you don't have branded headphones, try turning Virtual Surround on in the same section. This option works on the Dolby Atmos principle, but without licensed technology. The effect is less noticeable, but for movies and games it can add depth.
โ ๏ธ Warning: Spatial sound can cause discomfort during prolonged listening to music due to artificially shifting the sound scene. If you feel tired or dizzy, turn off the function.
4. Hidden Sound Features: Mi Sound Enhancer and Adaptive Settings
The new versions of MIUI 14/15 have hidden options that aren't always visible in the main menu, one of which is Mi Sound Enhancer, a technology that analyzes your ear anatomy and adjusts the sound to suit it, to activate it:
- Connect the headphones and open the Settings โ Sound and vibration.
- Slip 5 times on the label Sound Quality (this will open the hidden developer menu).
- In the list that appears, find the Mi Sound Enhancer and activate it.
- Take a short test (you will be asked to listen to a few sound samples).
Another useful option is Adaptive Sound, which automatically adjusts the equalizer to the level of external noise, for example, in a noisy subway, it will amplify high frequencies to make the voice on the podcast clearer.
Settings โ Sound and vibration โ Adaptive sound โ EnableThis feature only works on smartphones with Qualcomm Snapdragon 8 Gen 1/2/3 and later (e.g. Xiaomi 13T Pro or Redmi K60 Ultra).

5. Sound problems: Why aren't the effects working?
Sometimes, sound effects may not apply to wireless headphones, and here are the most common reasons and solutions.
| Problem. | Possible cause | Decision |
|---|---|---|
| The equalizer does not affect the sound | Headphones use their own DSP (digital processor) | Turn off branded headphone software (such as Sony Headphones Connect) |
| No "Space Sound" option. | Incompatible headphone model or the old version of MIUI | Update your firmware or use third-party apps (e.g. ViPER4Android) |
| The sound is distorted at high volume. | Activated "Sound Amplifier" with aggressive settings | Reduce the gain level or turn off the option altogether. |
| Effects reset after reconnecting headphones | Failure in the Bluetooth stack | Forget the device in Bluetooth settings and connect again |
If none of these methods worked, try resetting your Bluetooth settings:
Settings โ Connections and Sharing โ Bluetooth โ Settings (โ๏ธ) โ Reset settingsโ ๏ธ Warning: After you reset Bluetooth, all the associated devices (earphones, fitness bracelets, smartwatches) will be removed. You'll have to reconnect them.
6. Third-party applications for improving sound
If the built-in tools of MIUI are not enough, you can install third-party applications to fine tune the sound. Here are the top-3 solutions:
- ๐๏ธ Wavelet is a free equalizer with support for LDAC and aptX. Allows you to create separate profiles for different headphones.
- ๐ Poweramp Equalizer is a plugin for the popular Poweramp player, but it works on its own. There are presets for different genres.
- ๐ง ViPER4Android is a powerful audio mod with support for Dolby Surround and XHiFi. It requires root or Magisk to work properly.
To install ViPER4Android on Xiaomi without root rights:
- Download APK from the official website (viper.lat).
- Install the application and open it.
- Enable the Compatibility Mode option in the driver settings.
- Reboot your smartphone.
Wavelet is the easiest solution for beginners.
- Open the app and give access to the sound settings.
- Choose your headphones from the list (or add them manually).
- Activate AutoEQ โ the algorithm will automatically select the optimal settings for your model.

If the sound is quieter after installing a third-party equalizer, check the audio effects settings in MIUI. Sometimes the system limits the volume when using third-party modifiers.
7. Sound optimization for specific scenarios
Sound settings should be adjusted to specific tasks, here are recommendations for different situations:
| Script | Recommended settings | Additional advice |
|---|---|---|
| Music (hip-hop, EDM) | Equator: +3 dB at 60 Hz, +2 dB at 230 Hz Spatial sound: Off.Amplifier: Medium | Use the Bass Preset as a Bass Bass |
| Podcasts, audiobooks | Equator: +1 dB by 3.6 kHz (clearness of voice)Adaptive sound: On.Noise suppression: Active | Turn off all effects if the voice sounds unnatural. |
| Movies, TV shows | Equalizer: Flat or "Cinema" Spatial sound: On (weak) Dolby Atmos: On (if any) | Turn on the Dialog Amplifier in the video player settings |
| Games (PUBG, Call of Duty) | Equalizer: +2 dB by 14 kHz (steps, shots)Spatial sound: On (Medium)Speed delay: Minimum | Use headphones with aptX LL for minimal latency |
For games, setting up the Bluetooth codec is especially important, to reduce the latency of the sound:
- Go to Settings โ Connections โ Bluetooth.
- Press the badge. โ๏ธ near the connected headphones.
- Select the Audio Codec and install the aptX Low Latency or LC3 (for LE Audio).
