Modern wireless headphones from Xiaomi and Redmi sub-brands offer impressive audio quality, but often by default their settings are far from ideal. Many users do not even suspect that their headset is capable of playing deep bass or pure high frequencies, because they do not change standard parameters.
In this article, we will take a closer look at how to customize sound profiles, activate noise reduction and finely adjust frequencies. You will learn how to use the built-in capabilities of the MIUI and HyperOS operating system, as well as third-party applications to achieve studio quality. Proper calibration will take only a few minutes, but the result will exceed your expectations.
Before you make any changes, make sure your headphones pair correctly with your smartphone. Often, the sound quality issues are not the settings, but the weak battery charge or contamination of the speaker grids. Make sure that the firmware device is relevant, as manufacturers regularly release patches that improve connection stability.
Use of the built-in equalizer MIUI and HyperOS
Xiaomi’s operating shells provide a powerful native audio management tool that users often ignore. The standard equalizer allows you to change the frequency balance by amplifying or weakening certain ranges. You don’t need to download third-party software to access these settings, just go to the system menu.
Go to Settings → Sound and Vibration → Sound Effects. Here you will see the Mi Sound Enhancer switch, which is worth activating. Once turned on, you will have access to a graphical equalizer where you can choose presets or create your own profile, which is a basic but effective way to improve your music experience.
The system offers several preset modes, such as Bass, Vocal, Twitter and Flat. Flat disables any software enhancements, transmitting sound in its original form, which can be useful for audiophiles. However, for the mass consumer, modes with emphasized low or high frequencies are more interesting.
- 🎧 Bass: Ideal for hip-hop and electronics, enhances low-frequency range.
- 🎤 Vocals: Highlights the average frequencies, making the singer’s voice clearer and more legible.
- 🎻 Tweet: High-frequency, adding "air" and detail to the sound.
- 🎼 Flat: Disables processing, leaving the original signal unchanged.
⚠️ Warning: Excessive low-frequency amplification in Bass mode can lead to distortions (wheezing) at maximum volume, especially in compact headphone models.
If standard presets aren't enough, you can manually adjust each bandwidth. Move the sliders up or down to create a unique sound curve. Remember to keep your profile by giving it a clear name so you can quickly switch between use cases.
Xiaomi Earbuds app for deep customization
For owners of headphones series Redmi Buds, Xiaomi Buds and AirDots critically important to install the official application Xiaomi Earbuds (or Mi Buds), through this interface access to the firmware and advanced features not available in the standard Bluetooth menu. Without this application, you use only 50% of the gadget’s capabilities.
Once the headphones are connected and the app is running, the system will prompt a software update, a step that should not be missed, as new versions often include improvements to noise reduction algorithms and connection bug fixes, a process that takes several minutes and requires a stable Internet connection.
☑️ Checking before setting up
In the app's main menu, you'll find tabs for Active Noise Canceling (ANC) and Transparent Mode, and touch control settings are available here, where you can assign actions to single, double or triple touch, and long-term finger retention, allowing you to fully control the player and assistant without the need for a smartphone.
The audio settings section, which often features a separate equalizer that works independently of the system, is particularly noteworthy. In some models, such as the Xiaomi Buds 4 Pro, the adaptive sound feature is available, which automatically changes the noise reduction profile depending on the surrounding environment.
| Function | Description | Impact on sound |
|---|---|---|
| ANC (Active Noise Cancelling) | Active noise cancellation | Cuts off external noise, improving detail |
| Transparency Mode | Transparency regime | Skips external sounds without changing the equalizer |
| Game Mode | Game mode | Reduces latency, can change frequency characteristics |
| Wind Noise Reduction | Wind protection | Filtering the noise of the wind when talking outside |
💡
Enable Game Mode only during games, as it can increase power consumption and slightly change the frequency balance to the detriment of music quality.
Remember to check the About section of the app periodically, and that's where the firmware version and the serial number are displayed. If the headphones are acting weird (the sound is lost in one channel), resetting the settings through the app often solves the problem faster than reconnecting.
Configure Bluetooth codecs and transfer quality
The quality of wireless audio depends on the codec used. The codec is an algorithm for compressing and transmitting audio data. The standard SBC codec provides basic quality, but modern Xiaomi headphones support more advanced formats such as AAC, aptX and LDAC.
To check and change the codec, you need to activate the developer menu in Android. Go to Settings → About phone and quickly click on the build number seven times (MIUI Version). Once the message "You became a developer" return to the main settings menu, select "Additional" → "Developers".
In the list of options, find the Audio section and the Bluetooth Audio Codec. Here you can choose the available codec. If your headphones support aptX Adaptive or LDAC, be sure to choose them for maximum bitrate. However, remember that using high-quality codecs requires a more powerful processor and a stable signal.
What if a high codec is not on the list?
It’s worth noting that switching to a high-resolution codec can reduce the battery life of headphones. Complex compression algorithms require more processing power, leading to an accelerated discharge of the battery. between quality and autonomy – the choice of each user.
You can also find the "Bluetooth Audio Sample Rate" and "Bits per sample" settings on the developer menu, setting the values of 96,000 Hz and 32 bits respectively, you can achieve smoother sound, if the hardware of the headphones allows.
Activation of Dolby Atmos and Spatial Sound
Many Xiaomi smartphones feature Dolby Atmos technology, which creates a surround sound effect even in stereo headphones, which is especially effective when watching movies and TV shows, as it virtualizes the position of sound sources in the space around the listener.
To turn on, go to Settings → Sound and Vibration → Sound Effects and find the Dolby Atmos switch. From the technology menu, you can select the profile: Automatic, Video, Music or Voice. For headphones, the best fit is the Music profile or manual tuning mode.
In manual mode (HeadiPhone), you can fine-tune the virtualizer's parameters in detail. The Modulator slider is responsible for the width of the sound scene. You shouldn't twist it to the maximum, because it can lead to loss of the centralization of sound and the effect of "sound in the head."
- 🎬 Cinema: Expands the diaphonic base, making explosions and special effects more powerful.
- 🎵 Music: Balances frequencies for more natural sounding of instruments.
- 🗣 Voice: Focuses on medium frequencies for clarity of dialogue.
- 🎮 Games: Optimizes positioning of steps and shots in 3D-space.
⚠️ Warning: Turning on Dolby Atmos may conflict with third-party equalizer apps. If the sound becomes distorted, try turning off one of the effects.
Spatial Audio also depends on the gyroscope in the headphones (if there is one). In supported models, turning the head will change the sound pattern, creating the illusion that the sound source is static, and you move around it. This requires calibration through the application of headphones.
Third-party applications for professional calibration
If built-in tools are not enough, third-party solutions from the Google Play Store come to the rescue: Poweramp Equalizer or Wavelet allow deep correction of the frequency response (AFR), which runs on top of the system sound and can override Android settings.
Wavelet is notable for having an auto equalizer base for hundreds of headphone models. If your Xiaomi or Redmi model is on the list, the app will use a corrective profile to align the sound to the reference one, which is the best way to remove the specific "failures" or "humps" of the frequencies of a particular model.
Other applications allow for complex sound processing chains, including compressors, amplifiers and real-time spectrum analyzers, but using such tools requires some knowledge of audio engineering to avoid overprocessing sound.
💡
Third-party equalizers can consume extra battery power, as the processor is forced to process the audio stream in real time.
When installing a third-party equalizer, make sure it has the necessary permissions in the system. In newer versions of Android (12, 13, 14), access to audio sessions is strictly regulated, and the application may not work without granting special rights through the ADB or special features menu.
Resolving Typical Sound Problems
Even after perfect setup, technical problems can occur, and one of the most common is desynchronization of audio and video or intermittent playback, often solved by clearing the Bluetooth cache in the developer menu or completely forgetting the device and re-pairing.
If the sound is quiet or gone in one headphone, check the absolute volume settings. There's a "Switch off absolute volume" item in the developer menu. It can synchronize the phone's volume sliders and headphones to solve the silent sound problem.
Also worth paying attention to the physical condition of the headphones. The speaker grid can be clogged with earwax, which critically reduces volume and removes high frequencies. Careful cleaning with a soft brush often returns the device to its original sound without any software settings.

Customizing sound is creative and personal. What's perfect for one genre may not work for another. Experiment with combinations of equalizer, codecs and Dolby effects to find your unique sound. Remember that updating your firmware regularly through the app is the key to ensuring that all features work well into the future.
