How to adjust wireless headphones on a Xiaomi phone: the complete guide

Wireless headphones have become an integral part of everyday life, but setting them up on Xiaomi smartphones often raises questions among users. Even if you successfully connected a headset over Bluetooth, this does not guarantee perfect sound or stable performance. Problems can range from quiet sound to constant communication breakdowns, and standard MIUI settings do not always solve these problems.

In this article, we will discuss not only the basic steps of connection, but also hidden features that will help fine-tune the sound, optimize power consumption and eliminate typical problems. We will focus on the models of Redmi Buds, Xiaomi AirDots and other popular headsets, as well as the specifics of working with the firmware MIUI 14/15. If you encounter the fact that the headphones are connected, but the sound is interrupted or one of them is quieter, here you will find solutions.

1. Basic wireless headphone connection to Xiaomi

Before adjusting the sound or settings, you need to connect the headphones correctly, and the process may vary depending on the model of the headset, but the overall layout remains similar for most devices.

First, make sure the headphones are charged and paired.

• 🔋 Hold the power button on the case case case (for Redmi Buds 4 Pro - 3 seconds until the indicator starts flashing white / blue).
• 📱 On the smartphone Xiaomi to open Settings → Bluetooth and enable device search.
• 🔍 In the list of available devices, select the name of your headphones (for example, Mi True Wireless Earphones 2).
• ✅ Confirm the conjugation, if necessary.

If the headphones don’t appear in the list, try:

1. Reboot the Bluetooth module on the phone (disable / turn on in the notification curtain).
2. Reset the headphone settings (usually this is done by holding the button on the case for 10-15 seconds before changing the color of the indicator).
3. Make sure the headphones aren’t connected to another device (like a laptop or tablet).

💡

If your headphones support the LE Audio protocol (e.g. Xiaomi Buds 4), turn it on in Bluetooth settings → Additional → Codecs. This will improve sound quality and reduce latency.

2. Set up the sound profile and equalizer

By default, MIUI uses a standard audio profile, which is not always optimal for wireless headphones. To improve the sound, use the built-in equalizer or third-party applications.

To access the settings:

1. Open Settings → Sound and vibration → Sound quality.
2. Select the Equalizer and activate it.
3. Select a preset profile (Bas, Rock, Jazz) or set up sliders manually.

For models Redmi Buds 3 Pro and later available additional settings in the proprietary application Mi Earphones (download in Google Play):

• 🎵 Sound mode: Balanced, Enhanced bass, Clear high.
• 🔊 ANC (Active noise cancellation: control of the level of suppressed noise.
• 🎧 Transparent mode: for conversations without removing headphones.

Important: For models with LE Audio support (e.g. Buds 4), the Dynamic Quality option is available in MIUI 15, which automatically adjusts bitrate depending on connection stability.

3. Solving communication interruptions and sound delays

One of the most common problems is interruption of sound or delay when watching a video, which can be related to:

• 📶 Interference from other devices (Wi-Fi routers, microwaves).
• 🔋 Low-charge headphones or phone.
• 📱 Outdated firmware MIUI headphones.

To fix the problem:

1. Update the phone firmware (Settings → About the phone → System Update).
2. Reset Bluetooth settings (Settings) → Bluetooth → ⚙️ → Reset the settings).
3. Turn off dual audio (if multiple devices are connected at the same time).
4. Check the codec settings: go to Bluetooth Settings → ⚙️ headphone-on → Codec and select. SBC (more stable but with worse quality; or AAC (Best quality, but delays are possible).

⚠️ Note: If the audio delays only appear in specific applications (for example, YouTube or TikTok), the problem may be in the settings of the application itself.

4. Optimization of energy consumption and operating time

Wireless headphones discharge faster if you use functions like ANC or transparent mode, to extend the running time:

• 🔋 Turn it off. ANC, if not needed (in the Mi Earphones app or through touch control on headphones).
• 📴 Reduce the volume to a comfortable level – high volume significantly reduces the operating time.
• 🔄 Turn off automatic connection to the headphones when they are removed from the case (Bluetooth Settings) → ⚙️ → Auto-connection).
• 🌙 Enable the power saving mode on the phone (Settings) → Battery → Power saving mode, but note that this can impair the stability of Bluetooth connections.

For models with fast charging support (such as Redmi Buds 4 Active), 5 minutes in a case can give you up to 1 hour of playback.

• The state of the battery in the case (with severe wear, the capacity falls by 30–40%).
• The presence of background applications that actively use Bluetooth (for example, fitness trackers).
• Ambient temperature - at sub-zero temperatures, the capacity of lithium polymer batteries is temporarily reduced.

5. Touch control and gesture tuning

Most Xiaomi wireless headphones support touch control, but its setup is not always obvious. The following gestures are available by default (for Redmi Buds 3 Lite and later):

• 👆 One touch: playback/pause.
• 👆👆 Double touch: the next track.
• 👆👆👆 Triple touch: previous track.
• 👆Retention: Enabling the voice assistant or disabling ANC.

To reassign gestures:

1. Open the Mi Earphones app.
2. Choose your headphone model.
3. Go to the Control or Gestures section.
4. Assign new actions for each touch (e.g., double tap to call the voice assistant).

For models without an official application (for example, Mi Basic 2), gestures are configured only through standard MIUI tools:

1. Go to Settings → Connected devices → Headphones → Settings.
2. Choose Gesture Management (not available for all models).

⚠️ Attention: On some firmware MIUI touch control may conflict with system gestures (e.g. swipe to backtrack). → Display. → System navigation.

6. Update to the headphone firmware

The manufacturer regularly releases updates for wireless headphones that fix connection errors, improve sound or add new features.

For supported models OTA-Updates (Redmi Buds 4 Pro, Xiaomi Buds 4):

1. Put the headphones on the phone.
2. Open the Mi Earphones app.
3. If an update is available, a notification will appear with the Update button.
4. Confirm the update and wait for completion (earphones should lie in a case with an open lid).

For older models (for example, Mi AirDots), firmware updates are possible only through a PC using the official Xiaomi Bluetooth Tool software.

1. Download the utility from the official website of Xiaomi.
2. Connect the headphones to the PC via Bluetooth.
3. Launch the utility and follow the instructions on the screen.

💡

Updating the firmware can reset the user's headphone settings (such as gestures or equalizer).

7. Resetting headphones to factory settings

If the headphones are unstable, do not connect or have software failures, a complete reset will help.

For Redmi Buds 3/4 Pro and Xiaomi Buds:

1. Put both earphones in the case.
2. Open the case lid.
3. Hold the button on the back of the case for 15-20 seconds until the indicator flashes red and white.
4. Close the lid and wait 10 seconds.
5. Connect the headphones again via Bluetooth.

For Mi AirDots and Redmi AirDots:

1. Remove the headphones from the case.
2. Hold the touch panels on both headphones for 10 seconds until the indicators go out and blink again.
3. Place the headphones back in the case and reconnect.

⚠️ Note: After reset, the headphones may temporarily appear in the list of Bluetooth devices as LE-... Or they're not called correctly. Remove them from the list and reconnect them.
