How to connect wireless headphones to Xiaomi: from pairing to codecs

Xiaomi's modern smartphones have long ceased to be just a device for calling, turning into powerful multimedia centers. POCO frequently TWS-Headsets to enjoy high-quality audio without wires, but the initial setup process is sometimes difficult, especially for those who first switched to the shell. MIUI Standard connection algorithms can work differently depending on the version of the operating system.

In this article, we will discuss how to pair devices correctly, avoid common errors and make the most of the capabilities of the Bluetooth interface. You will learn about hidden codec settings that can dramatically change the perception of music. We will also touch on the issues of connection stability, since interference in crowded space can significantly affect the comfort of listening.

Equipment Preparation and Bluetooth Activation

The first step before any synchronization procedure is to check the readiness of both devices. Make sure that your Xiaomi smartphone has a wireless module on. To do this, lower the swipe notification curtain from top to bottom and find the Bluetooth icon. If it is on blue, the module is active. Otherwise, click on the activation icon.

The most common mistake users make is trying to find headphones when they're in sleep mode. TWS-Headphones require removal from the charging case to go into detection mode. QCY Or Haylou, which might require a long-term touch zone retention on the headphones themselves, and without that, the phone simply won't see the new device on the list of available devices.

Pay attention to the battery charge. If the headphone battery is critically low, they may not enter pairing mode or quickly shut down during the setup process. It is recommended to keep the case charged at least 30-40% before starting treatments. This is especially true for devices that have been lying unused for a long time.

To save your smartphone charge, turn off geolocation while searching for devices if it is not required, as scanning the Bluetooth environment can consume resources. GPS-module.

Step-by-step instructions for pairing devices

The MIUI and HyperOS interfaces are standardized, but they have their own nuances. Once you activate Bluetooth on your smartphone, go to the main Settings menu. Find the Bluetooth section, or search for settings by typing in the appropriate query. The system will automatically search for available gadgets within range.

At this point, you need to put your headphones in (pairing) mode. Usually, a flashing indicator (often white or red-blue) signals this. Once the model name appears in the list of "Available devices" on the phone screen, just tap it. The system can request confirmation of the access code, which is often 0000 or 1234, but modern models do without this.

Once successfully connected, the smartphone may offer an additional headset management app. In the Xiaomi ecosystem, it is often Mi Earbuds or universal Xiaomi Earbuds. Installing such software allows you to update the firmware of the headphones themselves, which sometimes corrects problems with desynchronization of the left and right channels.

⚠️ Warning: If there is no sound after connecting or only works in one headphone, try Forget Device in the Bluetooth menu and repeat the procedure again, having previously reset the settings of the headphones themselves.

Customization of sound quality and codecs

Many users are unaware that standard audio transmission settings may not provide maximum quality. Xiaomi smartphones support various compression codecs such as SBC, AAC, aptX and LDAC. By default, the system often chooses the most compatible, but not the highest quality option. To change these parameters, you will need access to the developer menu.

To activate hidden settings, go to About Phone and quickly click on MIUI version or build number seven times. You will notice that the developer mode is activated. Then go back to the settings menu, find optional and select For Developers. In the set list, scroll down to Audio block.

Here you'll find the Bluetooth Codec, and you can click on it to choose your preferred transmission format, and if your headphones support aptX HD or LDAC, these options will allow you to hear more music detail, but it's worth remembering that better codecs require more power and can drain the battery faster.

Table of compatibility and characteristics of codecs

Understanding the difference between compression formats will help you choose the optimal balance between quality and autonomy. Below is a comparative table of the main codecs supported by Android devices.

The choice of a specific codec depends not only on the support of headphones, but also on the listening conditions. In a noisy subway or on the street, the difference between aptX and AAC may not be so noticeable due to external noises. In the quiet of the apartment, using LDAC will unlock the full potential of an expensive acoustic system or studio headphones.

Solving Connection and Sound Problems

Even when set up correctly, there can be disruptions. Often users are faced with a situation where the phone sees the headphones but does not connect, or the connection is constantly breaking. First of all, check if the device is connected to another gadget. Bluetooth headsets often automatically try to connect to the last used phone or tablet.

Another cause of instability can be interference in the 2.4 GHz range. If a powerful Wi-Fi router or microwave is running nearby, the signal may be interrupted. Try to move away from the source of interference. It is also worth clearing the Bluetooth cache on the smartphone through the application menu by finding the Bluetooth system process in the list and selecting “Clean”.

• 📶 Reboot your smartphone and headphones – it solves 80% of software glitches.
• 🔄 Remove the device from the list of coupled and perform again.
• 🔋 Check if the case of headphones is discharged, as a weak charge causes module failures.

If the problem persists after all the manipulations, it may be hardware compatibility or a defect. In rare cases, a full reset of the network settings on the smartphone helps, but this will delete all stored Wi-Fi passwords and Bluetooth settings.

⚠️ Note: Before resetting your network, make sure you remember passwords from important Wi-Fi networks, as it will not be possible to restore them automatically.

Use of special MIUI and HyperOS functions

Xiaomi’s shells offer unique features for the brand’s headphone owners, and when you connect original accessories like Mi True Wireless Earbuds or Redmi Buds, you automatically display animations with a charge of the case and each headphone separately, which allows you to visually monitor the battery status.

Mi Sound Enhancer is also available in the audio settings, which adapts the frequency response to the type of headphones you use. You can choose the Intrachannel, Overhead or Column profile. Experiment with these settings to find the sound that is most pleasing to your ears. Sometimes turning on this option makes the sound more voluminous.

The low-latency feature (Game Mode) is activated by triple touching the touch zone (if supported by the model) or via a companion app, which minimizes the latency of sound, which is critical for rhythm games and shooters, where the count is in milliseconds.

Using native applications and features MIUI Sound Enhancer allows you to unlock the potential of the audio track of the smartphone, making the sound cleaner and more balanced.
