Owners of wireless headsets from the Chinese tech giant often face the need to fine-tune the audio stream to their personal preferences. Standard factory settings are not always able to satisfy the needs of audiophiles or users accustomed to specific sounds. That is why the question of how to change the sensitivity of Xiaomi headphones remains one of the most popular in the communities of owners of smart equipment.
Sensitivity in this context is often not only about maximum volume, but also about the balance of frequencies that directly affects the perception of details in music or the clarity of voices during calls. Modern models such as the Xiaomi Buds 4 Pro or the more affordable Redmi Buds 4 Active have complex internal signal processing architectures. Understanding the principles of these systems allows you to unlock the potential of the device by one hundred percent.
In this article, we will discuss in detail the software and hardware methods of influencing the sound profile, you will learn what hidden features are available through the Xiaomi Earbuds app and how to use Android system settings to achieve the perfect result.
Software configuration through the Xiaomi Earbuds app
The main tool for managing audio parameters is the official Xiaomi Earbuds application (formerly known as Mi Buds M8 or simply Xiaomi Earbuds). This is where the main levers of influence on the audio signal are concentrated. After pairing the headset with the smartphone, you need to open an application that automatically determines the model of the connected device and offers the current management interface.
Inside the user interface, what you're interested in is the section that handles the sound profiles, and you can find preset modes like Balance, Bass, Vocals or Twitter, and choosing a particular profile actually changes the equalizer curve by amplifying or attenuating certain frequency bands, which is the first step to changing the subjective sensitivity of sound perception.
Special attention should be paid to the Mi AI Sound function, or adaptive equalizer, if your model supports this technology. The algorithm analyzes the structure of the user's ear and automatically selects the optimal sound profile.
⚠️ Attention: Using the adaptive sound function can significantly increase the battery consumption of the headset, as the headphone processor operates in enhanced mode to process the signal in real time.
Some advanced models allow you to manually move the sliders of the equalizer, which allows you to create your own preset, where, for example, high frequencies will be twisted to the maximum for greater detail, and low slightly fine-tuned to eliminate the hum, this flexibility makes software customization indispensable for demanding users.
Android System Settings and Engineering Menu
If the proprietary app is not enough, the system settings of the Android operating system, which runs the MIUI shell or HyperOS, often hide additional options in the Sound and Vibration section, which are ignored by most users, and you can find absolute volume settings that directly affect the output level.
You can use an engineering menu or special codes to access deeper settings, although these depend on the regional firmware version and the specific smartphone model. Entering a command into a dialer code allows you to go to the hardware testing menu, where speaker and microphone checks are available.
One of the key features is to turn off the "Absolute Volume" in the developer menu, which is a setting that allows you to adjust the volume of your smartphone and headset, so you can squeeze the maximum out of the speakers, and you have to click on the build number several times to get into the developer menu in the "About Phone" section.
In the developer menu, find the item "Switch off absolute volume." Switching this switch can dramatically change the behavior of the volume slider. In some cases, this solves the problem of quiet sound, when even at maximum music is not loud enough, this is especially true when connected to third-party devices that are not products of the Xiaomi ecosystem.
- 🎧 Absolute Volume – a feature that synchronizes the volume levels of the phone and Bluetooth device.
- 🔊 Codecs – in the developer menu you can also select the codec for audio transmission (SBC, AAC, aptX, LDAC), What affects quality and delay.
- ⚙️ Developer menu – a hidden settings section that requires activation through multiple clicks on the build version.
💡
If the sound becomes too quiet after turning off absolute volume, try to reduce the volume on the phone to a minimum, and then add it again to a maximum - this will reboot the audio driver.
Use of third-party equalizers and amplifiers
When regular funds are scarce, third-party apps from the Google Play Store enter the arena, equalizers allow complex audio processing chains to be created by overlaying filters before the signal reaches the Bluetooth module, a powerful way to customize sensitivity to a particular genre of music.
One of the most popular solutions is the Poweramp Equalizer or Flat Equalizer app, which gives users access to a 10-band or even more detailed equalizer, so you can raise frequencies in the 2-4 kHz range for greater vocal brightness or add air at frequencies above 10 kHz.
If you see that the sliders have gone into the red zone and the sound has become hoarse, you need to reduce the total (Gain) or lower the most elevated frequencies.
| Annex | Type of access | Impact on the battery | Difficulty setting up |
|---|---|---|---|
| Xiaomi Earbuds | Official | Low. | Low. |
| Poweramp Equalizer | sideways | Average. | Medium |
| Wavelet | sideways | Low. | Tall. |
| Bass Booster | sideways | High. | Low. |
Another tool is amplifiers that simply increase the overall signal strength, which are software compression, which can raise the level of quiet sounds, but using these boosters can often increase the dynamic range, making the music flat and inexpressive.
What is AutoEQ in Equalizer Apps?
Microphone problems and sensitivity when calling
Sensitivity is important not only for music playback, but also for voice transmission. If people complain that you are not heard well, or, conversely, your voice sounds like a barrel, the problem may lie in the noise reduction settings. The Xiaomi Earbuds app often has a noise reduction (ANC) and transparency switch.
Transparency Mode uses external microphones to pass ambient sound. If activated by accident, it can echo or change the timbre of your voice in the ears of the interlocutor due to feedback. Make sure that during important conversations, the Noise Suppression or Normal mode is turned on.
It is also worth checking the physical microphone holes on the headphones themselves. In models like Xiaomi Buds 3T Pro, the microphone holes are located on the leg; contamination with earwax or dust can reduce the sensitivity of the microphone by 50% or more; regular cleaning with a soft dry brush is a mandatory procedure.
⚠️ Warning: Do not use sharp objects or alcohol to clean the microphone mesh.This can damage the microphone membrane and permanently disrupt the device.
In some cases, reconnecting the device helps: Remove the headset from the Bluetooth list on the phone, put the headphones in the case, close the lid for 10 seconds, and then pair again. This resets temporary errors of Bluetooth drivers that can affect the microphone.
Resetting settings and reconnecting the device
If the program dances with the drum don't work, and the sound remains unnatural or quiet, there may have been a software failure in the headset memory, in which case the method is a complete factory reset, which will return all the internal parameters of the equalizer and sensitivity to the original state.
Reset procedure is usually done by holding the touch zones on the headphones themselves. For example, for many Redmi Buds models, you need to place the headphones in a case, open the lid and pinch the touch areas on both headphones simultaneously for 10-15 seconds until the indicator flashes orange.
☑️ Checklist before resetting headphones
After a successful reset, the indicators should flash white or red (depending on the model), signaling readiness for a new pairing. Be sure to reconfigure the headset through the app, as all your previous presets will be removed. This often solves problems with channel desynchronization or floating volume.
It is important to understand the difference between software failure and physical wear. If after resetting and reconnecting to another smartphone, the sensitivity problem persists, it is likely to be the hardware part: wear of the dynamic head or oxidation of the contacts.
💡
Hard Reset eliminates 90% of software errors in the audio tract, but it is not able to fix the physical breakdown of the speaker or microphone.
