Modern Xiaomi and Redmi smartphones offer many ways to play multimedia content, but the quality of the built-in speakers is often inferior to external acoustic systems. Users are eager to connect wired or wireless headphones to get cleaner sound, deep bass and the ability to listen to music or watch movies without disturbing others. This is especially true in public transport or at night.
The process of pairing may seem simple, but in a shell MIUI or the new HyperOS, there are hidden settings that affect sound quality and connection stability. USB-Adapters can cause distortion or complete absence of audio. Understanding the nuances of connection will help to avoid common errors.
In this guide, we will take a look at all the available methods, from classic Bluetooth to external DACs. You will learn how to set up an equalizer for perfect sound and what to do if the phone stops seeing audio devices. Note that for models without a 3.5 mm connector, using a quality adapter is critical to maintaining Hi-Fi quality.
Connecting wireless headphones via Bluetooth
The most popular way to use a headset with a phone is wireless. Bluetooth technology provides sufficient bandwidth to transmit high quality sound, allowing the user to move freely. To start, you need to activate the appropriate module in the smartphone system.
Open the notification curtain with the swipe from top to bottom and find the Bluetooth icon. If it's not on the first screen, click on the edit pencil or the Change button to add the widget. You can also go to the Settings β Bluetooth menu and switch the slider to the active position.
Now, put your headphones in pairing mode. Usually, you need to press the power button or the special Bluetooth button for 5-7 seconds until the indicator flashes quickly in blue or red and blue. The name of your headset will appear on the list of available devices on the smartphone screen. Press it to complete the pairing.
Sometimes the process can take longer if there are many other active devices around. Make sure the headphones are close enough to the phone. If the device is found but not connected, try removing old entries about it from the list of previously connected gadgets and repeat the procedure again.
Use of wired headphones and adapters
Many flagship and mid-budget Xiaomi models lack the standard 3.5 mm connector, which forces users to use adapters or digital headphones with a USB-C connector. The connection in this case occurs automatically: just insert the plug into the charging port.
Cheap adapters often don't have a built-in digital-to-analog converter (DAC), which can result in quiet or no sound. The system may not recognize the device if the adapter doesn't meet the phone's specifications. It's recommended to use original accessories or certified analogues.
If you use a 3.5mm wired headphone and adapter, make sure that no dust or pile gets into the port, which can interfere with tight contact. Carefully clean the charging connector with a wooden toothpick or antistatic brush before connecting.

Customization of sound and equalizer in MIUI and HyperOS
After successfully connecting the headphones to the Xiaomi Mi, it is important to properly adjust the sound profile. Standard settings are often too flat, but the built-in equalizer allows you to significantly improve the sound. Go to Settings β Sound and vibration β Sound effects.
Here you'll find a few preset profiles, like "Bas," "Vocal," or "Jazz." Choose the one that best suits your genre of music. For more fine-tuning, use the manual equalizer mode, raising or lowering frequency sliders. Low frequencies are responsible for bass, high frequencies are responsible for clarity and detail.
You should pay special attention to Dolby Atmos technology if it's supported by your model, which creates a surround sound effect, which is especially noticeable when watching movies and games, and you can activate it in the same audio effects menu by selecting the appropriate profile or by turning on automatic mode.
Don't forget to adjust the left-right balance. If you feel that one of the headphones has a quieter sound, check the settings for special features. Sometimes a software balance shift can be mistaken by the user for a speaker malfunction.
Secret codes for sound testing
Solving Connection and Sound Problems
Despite the stability of Android, users sometimes face situations when the headphones do not work or the sound is interrupted. One common cause is a conflict of Bluetooth profiles. If the phone "sees" the device but does not transmit sound, try in the Bluetooth settings to press the gear next to the headphone name and make sure that the Multimedia switch is active.
Another common problem is desynchronization of audio and video, which is often the case with high-resolution codecs on older versions of Bluetooth, which will help reset network settings. Go to Settings β Connection and Sharing β Reset Wi-Fi, mobile networks and Bluetooth. Note that this action will delete stored Wi-Fi passwords.
If the sound wheezes or is interrupted, check if the power saving mode is on. Aggressive battery optimization can limit the background operation of the Bluetooth module. Add the application through which you listen to music to exceptions or remove the restrictions of background activity.
β οΈ Warning: If the sound in the headphones is gone after the firmware update, the problem may be the drivers. Try turning off the absolute volume level in the developer menu.
Use of high-resolution codecs
For audiophiles using expensive headphones, it is important to support advanced codecs such as aptX HD, LDAC or LHDC. These technologies allow you to transfer more data, providing sound close to studio quality.
You can check and change the codec you're using in the developer menu. To activate this menu, you need to quickly click 7 times on the build number in the About Phone section. Then, in the advanced settings, find the Bluetooth Audio Codec and select the available option. If the desired codec is not on the list, then your device does not support it hardware.
Itβs worth remembering that using high-resolution codecs increases power consumption and can reduce headphone life from a single charge. In addition, with a poor Bluetooth signal, the system can automatically switch to the basic SBC codec to maintain connection stability.
| Codec | Sound quality | Delay (Latency) | Compatibility |
|---|---|---|---|
| SBC | Basic | Tall. | Universal. |
| aptX | Good. | Medium | Android, Qualcomm |
| LDAC | Hi-Res (excellent) | Tall. | Sony, Android 8.0+ |
| LHDC | Hi-Res (excellent) | Low. | Xiaomi, Huawei |

For minimal audio delay in games, use headphones with support for aptX Low Latency or game mode, which is activated in the Xiaomi Earbuds app.
