Modern wireless headphones from Xiaomi and its sub-brands such as Redmi and QCY are often equipped with advanced audio processing algorithms known as Mi Sound. This technology allows you to significantly improve the detail of the audio stream, add depth to the bass and expand the stereo, making listening to music a full pleasure. However, many users face difficulties when trying to activate this feature, since it is not always available through the standard Bluetooth settings of a smartphone.
Mi Sound activation requires special software and a certain sequence of actions. It often happens that even after successfully pairing the device with the phone, the desired sound mode remains hidden, this is due to the fact that the management of audio profiles is brought to individual service applications or depends on the version of the firmware of the headset, understanding these nuances will save you time and nerves.
In this guide, we will discuss in detail all the known ways to enable Mi Sound mode on Xiaomi headphones, including using the official Xiaomi Earbuds app and third-party utilities to activate hidden functions. We will look at compatible models, possible connection errors and methods for eliminating them. Ready device is only the first step to high-quality sound.
What is Mi Sound Technology and How Does It Work?
Mi Sound technology is a set of software algorithms developed by Xiaomi engineers to optimize the sound in wireless headphones. Unlike a conventional equalizer, which simply raises or lowers certain frequencies, Mi Sound dynamically processes the audio signal in real time, which allows you to compensate for the physical limitations of small speakers and the design of the body. TWS-headset.
The main purpose of this feature is to create a three-dimensional sound field and improve the legibility of the vocals. The algorithm analyzes the incoming data stream and applies (presets) that are most suitable for the current genre of music or type of content, this is especially noticeable when listening to compositions with complex instrumental arrangements, where it is important to separate each instrument from the overall mix.
It is worth noting that Mi Sound works directly on the data codec. For best results, it is recommended to use AAC or aptX codecs if your device and headphones support them. On a standard SBC codec, the effect may be less pronounced due to the limited bandwidth of the transmission channel.
⚠️ Warning: Activation of Mi Sound mode can lead to increased power consumption of headphones. battery life in active audio processing mode is reduced by about a half. 15-20%.
Users often confuse Mi Sound with the usual bass amplification, but the difference lies in the depth of processing: if the equalizer simply adds low frequencies, Mi Sound restructures the entire sound scene to make it wider and more detailed, which is especially important for fans of classical music, jazz and live concert recordings.
List of compatible headphone models Xiaomi and Redmi
Not all of the Chinese giant’s wireless headsets support Mi Sound, a technology that has been introduced gradually since generations of devices, and is mainly available in mid-range and flagship models, as well as some budget series released after 2020.
To determine compatibility accurately, you need to know the exact model name, which is usually indicated on the box or in the Bluetooth system menu. Below is a list of devices that officially claim support for the technology or that have hidden potential to activate it through third-party applications.
- 🎧 Xiaomi Mi True Wireless Earphones 2 / 2S / 2 Pro – one of the first models with full support.
- 🎧 Redmi AirDots 3 / 3 Pro – a popular series with improved noise cancellation and sound.
- 🎧 Xiaomi FlipBuds Pro – flagship lineup with adaptive sound.
- 🎧 Xiaomi Buds 3 / 3 Pro – modern models with spatial audio.
- 🎧 QCY T13 / T17 — Some sub-brand models also received support for ecosystem functions.
It is important to understand that the presence of a feature in the list does not guarantee its automatic operation on any smartphone. Often, for full activation, you need to use a Xiaomi smartphone with a MIUI shell or HyperOS, where system permissions are already prescribed.
| Model headphones | Support for Mi Sound | Required annex | Year of release |
|---|---|---|---|
| Mi True Wireless 2 Pro | Yes (Native) | Xiaomi Earbuds | 2020 |
| Redmi AirDots 3 Pro | Yes (Native) | Xiaomi Earbuds | 2021 |
| Xiaomi Buds 3T Pro | Yes (Hi-Res) | Xiaomi Earbuds | 2022 |
| Redmi Buds 4 Lite | No (Basic Sound) | Not required | 2022 |
If your model isn't on the list, it doesn't mean you can't improve the sound. There are universal equalizer tuning methods that can mimic the Mi Sound effect. However, native support is always preferable, because the algorithms are tailored to the specific acoustic circuitry of the device.
Official method: activation through the Xiaomi Earbuds app
The most reliable and safe way to enable Mi Sound is to use the official Xiaomi Earbuds app. This software serves as a bridge between the smartphone operating system and the headphone microcontroller, allowing you to change the deep audio settings. Installing the app is the first step to unlocking the potential of your headset.
The installation process may vary depending on the region and version of your smartphone’s operating system. In some cases, the app is already built into MIUI and you just need to find it. In other situations, you will need to download the APK installation file or search the Google Play store.
Once the app is launched and the headphones are paired successfully, the interface will prompt you to update the device's firmware if a new version is available. Updating the firmware is a critical step, as support for new audio modes is often added with the latest security and functionality patches. Don't ignore this step.
In the main menu of the app, find the section that deals with sound effects, which can be called "Sound Effects", "Audio Effects" or simply "Mi Sound". The switch activates the processing algorithm. There are often presets available here: "Balance", "Bases", "Vocals", which can be customized to your preferences.
⚠️ Note: When installing an application from third-party sources (not Google Play), be sure to check the hash amount of the file or use proven resources to avoid infecting the device with malicious code.
If the sound hasn't changed after the switch is activated, try rebooting the headphones by placing them in the case and closing the lid for 10 seconds. Sometimes the microcontroller needs to reboot to apply the new DSP (Digital Signal Processor) settings.
Alternative methods and hidden settings MIUI
For Xiaomi, Redmi and POCO smartphone owners, there are built-in system tools that can work even without installing a separate Xiaomi Earbuds app. The MIUI shell has deep integration with the audio subsystem, allowing you to manage audio profiles directly through settings.
To get to the hidden settings, you need to go to the Settings menu → Sound and vibration → Sound quality and effects. This can be the Mi Sound Enhancer switch. In some versions of the firmware, this item is hidden and only activated when compatible headphones are found within range of Bluetooth.
Another method involves using third-party equalizer apps like Poweramp Equalizer or Wavelet. Although they don't include native Mi Sound, they allow you to create a profile as close as possible to the desired sound. Wavelet, for example, has an auto-correction (AutoEq) database for hundreds of headphone models, which can give even better results than standard algorithms.
Using third-party launchers or modified versions of MIUI can also open access to regional audio settings. For example, the Chinese firmware version often contains more audio chips than the global one.
- 📱 Use the built-in equalizer in the Mi Music player.
- 📱 Try activating Dolby Atmos in the sound settings if Mi Sound is not available.
- 📱 Install the Xiaomi Sound app (separate package for older models).
- 📱 Check the developer settings to change the Bluetooth bitrate.
The combination of these methods allows you to achieve high-quality sound even on devices where direct activation of Mi Sound is not possible, the main thing is to experiment with frequency settings to find a balance that is pleasant to your ear.
The solution to the problem: why Mi Sound does not work
Even if all instructions are followed, users may encounter a situation where Mi Sound does not turn on or does not work correctly. The most common reason is a conflict of software versions. If the Xiaomi Earbuds application is updated and the headphone firmware remains old (or vice versa), functions can be blocked by the security system.
The problem can also be in the cache of Bluetooth services, where accumulated pairing errors sometimes interfere with the transmission of service commands from the phone to the headphones, in which case it helps to completely reset the network settings or remove the device from the list of conjugated ones, followed by re-assignment.
If you force the SBC codec to be selected in your Bluetooth settings, some high-bitrate Mi Sound functions can be turned off automatically, as the channel bandwidth is not enough to transmit the processed signal. Check the developer settings in the Special Features section.
⚠️ Attention: Forced codec installation in the developer settings can result in complete absence of sound or strong wheezing. Return settings to the original state if you notice a deterioration in quality.
In rare cases, the problem is hardware in nature: if one of the headphones is discharged more than the other or has an antenna defect, the synchronization of the sound profile data may be interrupted, make sure that both earphones are charged and the contact areas of the case are clean.
Set up the equalizer for maximum quality
After successful activation of Mi Sound, it is recommended to fine-tune the equalizer. Standard presets are often a compromise solution. To get the perfect sound, you need to consider the genre preferences and acoustic features of the tracks you listen to most often.
In the Xiaomi Earbuds app or system equalizer, try creating your own profile. For electronic music and hip-hop, it's worth raising the low frequencies (60 Hz - 250 Hz) a little by adding "body" to the sound. For vocal music and podcasts, it's better to highlight the middle frequencies (1 kHz - 4 kHz) so that the speech sounds clear and legible.
High frequencies (10 kHz and above) are responsible for "air" and detail. Their over-raising can lead to whistles and hearing fatigue, so add them carefully. Mi Sound already works in this range, so often just leave the default settings or raise them by 1-2 dB.
Remember to revisit the settings periodically. Human hearing adapts, and what seemed like the perfect sound a week ago may require correction today. Regular calibration is a guarantee of constant listening pleasure.
