The problem of quiet sound in wireless headphones often becomes an unpleasant surprise for owners of budget models such as Xiaomi Redmi Airdots, Airdots 2 or Airdots 3. Despite the compact form factor and affordable price, users expect high-quality sound pressure, but sometimes faced with a situation where even the maximum volume of the smartphone seems insufficient. This can be due to both the software limitations of the Android or iOS operating system, and the peculiarities of synchronization of the headphones themselves.
In this article, we will discuss in detail how to increase the volume of Xiaomi Airdots headphones using proven equipment customization methods. We will look not only at standard adjustment sliders, but also at hidden engineering menus, specialized equalizer applications, and hardware reset methods that often help eliminate channel desynchronization. If your sound is quieter or initially does not meet the requirements, this article will be a comprehensive solution.
Diagnostics of the causes of silent sound in TWS-headsets
Before embarking on radical signal amplification measures, you need to understand the nature of the problem. Often the low volume in the Xiaomi Mi True Wireless Earbuds Basic is due not to a defect in the speakers, but to the desynchronization of the left and right channels. In this mode, one earphone can work at full power, while the second one operates in the background or with a lower signal level. This is a common software error characteristic of Bluetooth protocols in the budget segment.
Another reason could be a codec mismatch or a limitation of the smartphone operating system itself. Android, for example, has a separate multimedia volume slider that does not always correctly synchronize with the hardware volume of the connected headset. It is also worth considering the physical factor: the protective mesh of speakers is clogged with earwax and dust over time, which significantly reduces the permeability of the sound wave. Cleaning the acoustic holes is the first step before any software setting.
Sometimes the problem lies in the source of playback. Some video players or music services have their own amplification settings that can be disabled by default. Also, when switching between devices (for example, from iPhone to Android), the volume profile can get lost. It is important to exclude all external factors to understand whether you need software intervention or simple device hygiene.
⚠️ Warning: Before any manipulations, make sure your headphones are at least 50% charged. Interrupting the reconnection process or resetting settings on a low charge can cause the Bluetooth controller to malfunction.
Basic Bluetooth settings and channel synchronization
The most effective way to increase the volume of Xiaomi Airdots headphones without installing third-party software is to re-sync correctly. Often the left and right channels work independently, and one of them does not receive the full signal. To solve this problem, you need to perform a full pairing reset. First, remove the device from the list of paired in the Bluetooth settings of your smartphone by selecting the option “Forget the device” or “Disable”.
Then, place both earbuds in the charge case and close it. Then remove them at the same time and press both headphones on the touchpads simultaneously, holding for 5-7 seconds until the indicators turn red. This action initiates a reset to factory settings. Now re-search the device on the phone. In 80% of cases, this procedure equalizes the channel balance and returns the normal volume.
There is also a nuance associated with absolute volume in Android. In some MIUI or pure Android firmware, this feature can conflict with headphone drivers. Try turning off and re-enable Bluetooth on your smartphone after the headphones are already on. This causes the system to renegotiate volume levels. If you use an iPhone, check the settings under Settings -> Sounds, Tactile Signals -> Listening Security, where the volume limit can be activated.
☑️ Verification of synchronization
Use of engineering menu and Android codes
For advanced users who own Android smartphones, the engineering menu is a great tool for solving the problem of how to increase the volume of Xiaomi Airdots headphones. This is a hidden section of the system that allows you to adjust sound pressure levels at the software level, accessed through a standard “ringer” by entering special combinations. For most Xiaomi, Redmi and Poco devices, the code # #3646633# is relevant.
Once you enter the code, the CIT menu will open. You need to go to the Hardware Testing tab, then select Audio -> Audio Debug. Here you will see a list of profiles, such as Normal Mode (normal mode), Headset Mode (headset mode), and others. We are interested in a profile corresponding to media playback. Inside you need to find the Media or Music option. Make sure you are in the Output section.
In the window that opens, you will see volume levels from Level 0 to Level 6 (or higher). Level 6 usually corresponds to maximum volume. If the value in the Max Vol or Current Vol field is below the maximum (often 160 or 255 depending on the chipset), it can be neatly increased. However, be careful: excessively increasing the values can lead to the speaker wheezing or physical damage. After changing the parameters, press Set and restart the device.
⚠️ Warning: Changes in the engineering menu are made at your own risk, write down the initial values before changing, so that in case of deterioration in the sound quality (distortion) you can return everything as it was.
Boost Apps and Equalizers to Amplify Sound
If you don't have enough system settings, specialized applications from the Google Play Market come to the rescue, allowing you to programmatically amplify the signal beyond the standard OS constraints. One of the most popular and functional solutions is the Volume Control Plus or Precise Volume app, which creates a virtual control layer that can twist volume above the standard 100%.
Another powerful tool is Poweramp Equalizer, which is not just an equalizer, but a full-fledged audio processor, which allows you to not only adjust the frequencies, but also add pre-amp. By increasing the Pre-amp setting, you raise the overall signal level before sending it to a Bluetooth transmitter. This is especially effective for low-record tracks. It's also worth paying attention to the Bass Booster application, which often has a simple general-amp slider.
When using such programs, it is important to observe the measure. Digital amplification always introduces distortion (clipping) if the original signal is already close to the limit. The sound can become flat, metal or start cracking at high frequencies. The optimal amplification is considered to be within 10-15% of the maximum. Also remember that third-party applications consume the battery of the smartphone more actively, since the processor is forced to process the audio stream in real time.
Secret Functions of Equalizers
Comparison of volume-raising techniques
To make it easier for you to choose the right method, we have systematized the methods in a table, each approach has its advantages and disadvantages depending on your technical background and smartphone model.
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Reset settings (Reset) | Low. | High (with desynchronization) | Absent. |
| Engineering menu | Tall. | Maximum | Possible distortions, failure of the software |
| Booster applications | Medium | Medium/High | Battery consumption, sound artifacts |
| Cleaning the nets | Low. | Depends on pollution | Damage to the membrane with carelessness |
As you can see from the table, it's always the least risky thing to do. Mechanical cleaning and resetting solve most of the problems associated with sudden volume drops. Software methods are worth using if the standard capacity of the device is really not enough for comfortable listening in noisy environments, such as in the subway or on the street.
💡
The safest and most effective first step is to completely reset the headphones to factory settings, as this eliminates software-based channel dissynchronization without risking damage to the equipment.
Cleaning and maintenance of speakers
Don’t underestimate the physical condition of your Xiaomi Airdots. In six months or a year of operation, the protective net is clogged with microscopic particles of skin, sulfur and dust. This creates a dense cork that silences high frequencies and general volume. Use a soft toothbrush, slightly moistened in isopropyl alcohol (don’t urinate abundantly!).
Carefully brush the speaker grid, removing visible plaque. You can also use sticky tape (scotch) to apply it to the grid to pull the villi and dust from the depth. Under no circumstances use sharp objects such as needles or pins to avoid piercing the speaker membrane. After cleaning, allow the headphones to dry completely for 10-15 minutes before turning on.
Regular maintenance extends the life of the device and maintains the sound quality at the level of the new gadget. If after cleaning the sound is not restored, it may be a technical problem, for example, battery wear (which affects the signal power) or degradation of the speaker.
