How to connect wireless headphones to the smartphone Xiaomi: instructions for all models

Wireless headphones have become an integral part of everyday life — they are convenient for listening to music, calling and even watching videos. Xiaomi smartphone owners (including the Redmi series and POCO) often face questions: how to properly sync the headset with the phone, what settings optimize the sound, and what to do if the device is not detected.

The process of pairing headphones with MIUI (branded shell Xiaomi) has its own features, especially if we are talking about models with Bluetooth 5.2/5.3 or dual connection function (simultaneous connection with two devices).We will look at universal methods for all versions of the firmware, as well as individual instructions for popular headsets — Xiaomi AirDots, Redmi Buds, Haylou and other compatible accessories. If you just purchased new headphones or encountered a mistake when connecting, here you will find clear steps and practical tips.

Preparation of headphones and smartphone to connect

Before you start pairing, make sure both devices are ready to go. For Xiaomi smartphones, the key is the current version of MIUI - old firmware may not have drivers for new headphone models. You can check the version in the Settings menu → About Phone → MIUI version.

As for headphones, most models (such as the Xiaomi Buds 4 Pro or Redmi Buds 5) automatically go into pairing mode when first turned on, but if the headset has already been used with another device, it must be reset.

• 🔋 Make sure the headphones are charged (the indicator should flash or burn white/blue).
• 📱 Turn on Bluetooth on your smartphone (swipe down) → quick-setting panel).
• 🔄 To reset your headphone settings, hold the power button (or touchpad) for 10-15 seconds until the indicator flashes red and white.
• 🎧 Place the headphones in the case and open the lid – some models (for example, AirDots 3 Pro) activate the search mode only so.

If you use third-party headphones (like the Haylou GT6 or SoundPEATS Air3), check their compatibility with your smartphone's Bluetooth codecs. Current Xiaomi models support AAC,, and, but for better sound, it's recommended to choose AAC (optimized for Apple Music and Spotify) or (for low latency).

Step-by-step: Connect via Bluetooth

The standard way to pair headphones with a Xiaomi smartphone takes no more than a minute.

1. Open Settings on your phone and select the Bluetooth partition (or swipe down and hold the Bluetooth icon for quick access).
2. Activate Bluetooth if it's turned off. The smartphone will start scanning the available devices.
3. Put the headphones in pairing mode (see section above). Their name (such as Redmi Buds 5 or Mi True Wireless Earphones 2) should appear on the list.
4. Tap the headphone name on the list. If you have a request for code confirmation (usually 0000 or 1234), type it in.
5. Wait for the message “Connected.” In some models (for example, Xiaomi Buds 4) after pairing, you will need to confirm the connection to the case.

Once successfully connected, the headphones will automatically sync with the phone every time you remove it from the case (if Bluetooth is on).To speed up the process, add a Bluetooth widget to the home screen:

If the headphones don't show up on the list, try:

• 🔄 Reboot your smartphone and headphones.
• 📱 Remove all previously saved devices in Bluetooth settings (Conjugated devices section).
• 🔋 Check the charge of the case – some models (for example, AirDots Pro 2) do not activate Bluetooth at low battery level.

💡

If the headphones are connected but the sound is interrupted, try turning off the dual audio feature in Bluetooth settings, which can cause conflicts when you connect to multiple devices at the same time.

Customize sound and codecs for better quality

After connecting the headphones, you should optimize the sound parameters. In MIUI, special settings are provided for this:

1. Go to Settings → Sound and Vibration → Bluetooth Sound Quality.
2. Select the connected headphones from the list.
3. Set the priority codec: AAC is a balanced quality (recommended for music); aptX Adaptive is a low latency (for games and videos); LDAC is a high resolution (requires headphone support).

Activate the “Absolute Volume” option if you want to sync the volume level on your phone and headphones.

For models with ANC (active noise cancellation) (for example, Xiaomi Buds 4 Pro) additional modes are available:

If the headphones support customization of sound (for example, through the Mi Earphones app), you can adjust the equalizer to your preferences.

1. Download the official app from Google Play (for Xiaomi Buds or Redmi Buds).
2. Connect headphones and select one of the preset profiles (Bases, Vocals, Classic).
3. Use manually adjusting sliders for precise frequency adjustments.

Decision:

1. Charge the headphones (the indicator should burn red while charging).
2. Turn off Bluetooth on all other devices within a 10 meter radius.
3. Reset the headphone settings (hold the power button for 20 seconds until flashing red/white).

Problem 2: The sound is interrupted or distorted

This is most often related to:

• 📶 Weak Bluetooth signal (for example, if your phone is in your pocket and you are on the move).
• 🎵 Incompatible audio codec (for example, LDAC It can cause stuttering on old smartphones).
• 🔋 Low headphone charge (below 15%).

Decision:

1. Move the phone closer to the headphones (optimal distance is up to 1 meter).
2. In Bluetooth settings, select the AAC or SBC codec.
3. Turn off the “Double Audio” and “Absolute Volume” functions.

Problem 3: Headphones are connected, but there is no sound

Check it out.

• 🔊 Volume level on the phone and headphones (sometimes they are adjusted separately).
• 🎵 Selected audio source (in some applications, such as YouTube, you need to manually select Bluetooth output).
• 🔧 Settings Sound and vibration → Sound output (must be selected Bluetooth headset item).

💡

If Xiaomi headphones don't connect to your smartphone after the MIUI update, try rolling back the firmware or waiting for a patch. Often, Bluetooth bugs are fixed in the next versions.

⚠️ Note: If the Redmi Buds 3 Lite or AirDots 2 headphones only connect to one ear, check the synchronization between the left and right earphones:

1. Put both earphones in the case.
2. Remove them and hold the touchpads on both headphones for 5 seconds.
3. Wait for the double beep to confirm the successful synchronization.

Features of connection for different models Xiaomi

The pairing algorithm may vary slightly depending on the smartphone model and the MIUI version. Below are the key nuances for popular devices:

For smartphones with pure Android (such as Xiaomi A3 or POCO X5 5G), the connection process is standard, but there may be no support for branded features (such as Mi Super Audio).

If you are using a Xiaomi smartphone with custom firmware (like LineageOS), make sure that the build contains drivers for Bluetooth HAL. Otherwise, the headphones can connect, but without sound or distortion.

Additional features: dual connection and voice assistants

Modern headphones Xiaomi supports advanced features that can be activated after pairing:
