Budget owners TWS-Headsets are often asked about the possibility of activating active noise reduction (ANC) Xiaomi Mi True Wireless Earphones 2 Basic became a hit thanks to the excellent value for money, but many users confuse noise reduction technology when calling with a full-fledged phone. ANC It is important to note that this modification of headphones is not technically equipped with an active suppression system for external sounds in the listening mode of tracks, but has advanced voice cleaning algorithms.
Understanding the differences between ENC (Environmental Noise Cancellation) and ANC (Active Noise Cancellation) is critical to the proper operation of the gadget. If you expect that after turning on a certain feature, external noise will disappear completely, as in older Pro or Air models, you may be disappointed, since the physics of the speakers is different here. However, the competent setting of available parameters will significantly improve the quality of communication and listening comfort in noisy places.
In this article, we will take a closer look at exactly what noise reduction features are available in Xiaomi Mi True Wireless Earphones 2 Basic, how to activate them through the standard smartphone menu and third-party apps, and what software limitations are in place. You will learn why noise reduction sometimes seems to be worse than it should be, and how to fix typical connection errors that affect audio transmission.
Differences in noise reduction technologies in the basic model
The first thing that owners of this model need to learn is that there is no full-fledged active noise reduction (ANC) for music. Unlike more expensive versions such as the Mi True Wireless Earphones 2 Pro, it does not use outward-facing microphones to generate anti-noise. Instead, Xiaomi engineers have implemented ENC (Environmental Noise Cancellation) technology that works exclusively during voice calls.
The principle of the ENC is that the built-in microphones analyze background noise and cut it off when you transmit your voice to the interlocutor, which means that you will hear the world around you as clearly as you do without headphones, but your voice in the tube will sound clear. Attempts to find the "ANC On/Off" switch for music in this model will be unsuccessful, since such functionality is physically absent in the hardware.
⚠️ There are no hidden codes or combinations of touches that could activate active noise cancellation for the music on this model, as this requires a special processor and additional microphones.
However, the passive sound insulation of the Xiaomi Mi True Wireless Earphones 2 Basic is pretty good thanks to the design of the intra-channel headphones. Properly selected earbuds can create a similar effect to light noise cancellation, simply by snugly fitting into the ear canal, which allows you to cut off some of the high-frequency noise without using battery power.
How to activate microphone noise reduction (ENC)
Because ENC technology is built into the firmware of the headphones, it activates automatically when you start a voice call. You don't have to look for a separate button or switch in the Bluetooth menu. Once the phone connection is established and the conversation is underway, the noise reduction algorithms start to work in the background, analyzing the sound picture.
To ensure that this function works properly, it is important that both earbuds are paired with each other and connected to a smartphone. If only one headphone (mono mode) is running, the ENC efficiency may decrease as the system uses data from both microphones to position the voice source more accurately and cut off wind noise.
☑️ Verification of work ENC
It should be noted that the efficiency of the ENC depends on the density of the earphone to the ear. If the device is not tightly pressurized, the microphones can capture too many extraneous sounds, which will confuse the algorithms, in which case the interlocutor may complain of intermittent sound or the effect of "robotic" voice, which is a sign of overloading the noise cancellation system.
Using the Xiaomi Earbuds app to customize
While the Xiaomi Mi True Wireless Earphones 2 Basic is a budget model, it supports connection to the official Xiaomi Earbuds app (available on Google Play and the App Store), through which you can access additional equalizer settings and check the status of the device, which indirectly affects the perception of sound and noise.
Once you have the app installed and the headphones paired, you'll find the audio settings section on the device menu, and you can choose one of the equalizer's rods, like "Bas" or "High Frequency," and you can adjust the frequencies correctly to make your voice more legible against noise, which subjectively improves the noise reduction situation.
| Function in the annex | Description | Impact on noise |
|---|---|---|
| Double touch. | Adjustment of action with double tapa | No direct influence. |
| equalizer | Frequency balance adjustment | Improves legibility |
| Headphone search | Audible signal for search | Not applicable. |
| Firmware version | Information on the software version | Critical to the stability of the ENC |
Special attention should be paid to updating the firmware through the application. Xiaomi engineers periodically release patches that improve the algorithms of microphones and the stability of Bluetooth connection. If your headphones are not working correctly or making noise during calls glitch, checking updates is the first thing to do.
How to update the firmware through the application
Optimizing the sound profile for noisy places
Since there is no active noise suppression in Xiaomi Mi True Wireless Earphones 2 Basic, users can resort to software methods to improve the situation. In the settings of the smartphone itself (Android or iOS), there are often audio enhancement features or "mono-audio" that can help. The inclusion of mono-audio combines channels, making the sound denser and less susceptible to externalities.
Third-party equalizer apps are also recommended if standard settings are not enough. Increasing the mid-frequency (Mid) often makes the speaker or vocalist's speech clearer, allowing you to break through the background hum of transport or the street. However, beware: excessively amplifying high frequencies can lead to hissing that will be annoying.
The important aspect is to fit the headphones properly. The Xiaomi Mi True Wireless Earphones 2 Basic usually comes with interchangeable earpieces of different sizes. Using the wrong size leads to low frequency loss and external noise penetration. Experiment with size until you achieve maximum insulation.
💡
For better insulation on a noisy subway or bus, try a lightly twisted earphone in your ear after insertion so that silicone tightens the bends of the ear canal.
Typical problems and their solution
Users often experience a situation where the sound in one of the headphones is quieter or disappears, which is mistakenly perceived as a breakage of the noise maker. In most cases, the problem lies in contamination of the speaker mesh or microphone with earwax and dust. Regular cleaning with a dry soft brush or cotton swab (carefully!) can return the device to its previous efficiency.
Another common problem is the desynchronization of the left and right headphones, and if one earphone plays back or down, the ENC algorithms may not work properly, creating echoes for the other person, and this is solved by resetting the headphones to the factory settings.
To perform the reset, you need to place both headphones in the case, open the lid and pinch the touch zones on both headphones simultaneously for 10-15 seconds (or use the combination described in the instructions if the model requires retrieval).
⚠️ Warning: When performing a reset, make sure that the case is charged at least 30% so that the process is successful and the headphones do not discharge at a critical moment.
Comparison with the Pro and Air series models
If Xiaomi Mi True Wireless Earphones 2 Basic isn’t enough, it makes sense to consider older models. The Pro version already features a hybrid active noise cancellation (ANC) that actually quells the low-frequency hum of an airplane or train. The price difference between the Basic and Pro models is often justified by the presence of this module and support for the LDAC codec for Hi-Res audio.
Xiaomi Air 2 Pro also offers customizable noise cancellation with three modes (transportation, office, street).In the base version of 2 Basic, you are not able to switch between these modes, since the physical hardware does not support the generation of antiphase.
However, for a gym or jog, the lack of ANC in the base model can even be a plus: Complete isolation from the outside world on the street can be dangerous, as you won't hear the car's signal.In this context, the Xiaomi Mi True Wireless Earphones 2 Basic provide the optimal balance between sound and safety.
💡
The Basic is ideal for those who care about the purity of their voice when calling and safety on the street, but do not require complete silence for music.
