How to set up Xiaomi Bluetooth headphones: from connectivity to fine-tuning

Xiaomi’s wireless headphones are some of the most popular accessories, thanks to a combination of price, sound quality and functionality. However, even experienced users sometimes have difficulty with initial setup, synchronization between devices or activation of hidden features. This article will help you understand everything from basic Bluetooth connectivity to fine-tuning gestures, sound modes and solving typical problems.

We'll look at standard models like Redmi AirDots or Xiaomi Buds 4 Pro, but also look at the features of the Mi Earphones app, which gives you access to advanced settings. And if your headphones refuse to connect or malfunction, at the end of this article you will find a checklist for diagnosing and solving 90% of common errors.

1. Preparing Xiaomi headphones for the first connection

Before you start setting up, make sure your Xiaomi headphones are ready to go. Most models (like the Redmi Buds 5 or Xiaomi FlipBuds Pro) come in power saving mode, so you need to wake them up first.

• 🔋 Charge your headphones: even if the box says that the battery is partially charged, connect the case to the power source for 10-15 minutes.
• 📦 Remove the headphones from the case: most Xiaomi models automatically turn on when the lid is opened or the headphones are removed. If the indicators do not catch fire, press and hold the touch panel for 3-5 seconds.
• 🔄 Reset (if used): place both headphones in the case, then press and hold the button on the case (usually located behind) for 10-15 seconds until the indicator flashes red and white.

Important: If you connect your headphones to your iPhone or MacBook, upgrade your device’s firmware to the latest version. Some Xiaomi models (such as the Buds 3T Pro) require iOS 14+ or macOS Big Sur to work properly with the transparent mode feature.

2. Basic Bluetooth connection: step-by-step instruction

The process of connecting Xiaomi headphones to a smartphone or computer is almost the same for all models, but there are nuances depending on the operating system.

For Android (MIUI, Stock Android, Samsung One UI)

1. Open the Settings. → Bluetooth on your phone.
2. Make sure the headphones are in pairing mode (the indicator flashes white/blue).
3. In the list of available devices, find the name of your model (for example, "Redmi Buds 5") and tap it.
4. Confirm the connection if you request access to contacts or microphone.

For iOS (iPhone/iPad)

On iPhone, the process is similar, but after connecting, you may need to adjust the settings → Bluetooth → I icon next to the headphones, where you can select the priority of the sound (for example, phone calls or multimedia).

For Windows 10/11

On PC, go to Settings → Devices → Bluetooth, turn on search and select headphones. If no sound appears, check if they are selected as the default playback device in Control Panel → Sound.

Some Xiaomi models (like the Buds 4 Pro) support dual connectivity to two devices at once, so to activate this feature, connect the headphones first to the first device, then to the second one, which will automatically switch between them depending on activity.

3. Customization via the Mi Earphones app: advanced features

The proprietary Mi Earphones app (available for Android and iOS) lets you fine-tune sound, gestures and other settings. Download it from Google Play or the App Store.

After connecting headphones in the application, the following options will be available:

• 🎧 Equator: Pre-setting (bass, vocals, balance) or manual adjustment of bands.
• 👆 Gesture control: assigning one/double/triple touch actions (e.g. playback, voice assistant call).
• 🔊 Noise reduction modes: adaptive, transport, office or off.
• 🔋 Charge display: Percentage of battery of each headphone and case in real time.

For models with LDHC support (e.g. Xiaomi Buds 4 Pro), you can include this codec in the app for improved sound quality. However, note that LDHC only works with Android 10+ devices and requires activation in Bluetooth settings (enable Priritize audio quality or a similar option).

4. Solving Connection and Sound Problems

If Xiaomi headphones do not connect or work incorrectly, use this instruction:

⚠️ Warning: If the headphones are plugged in but the sound is interrupted or distorted, check if the phone is power-saving.

• 🔄 Reboot the headphones: Place them in the case for 10 seconds, then remove.
• 📱 Update your firmware: In the Mi Earphones app, check for updates for your model.
• 🚫 Remove “extra” devices: in Bluetooth settings, remove all old connections to the headphones, then pair them again.
• 🔊 Check the codec: in Bluetooth phone settings, select for headphones codec SBC or AAC instead LDHC, if the sound is distorted.

Critical error: if after updating the firmware headphones stopped turning on, place them in the case and connect the case to charge for 1 hour, 80% of the time this solves the problem of "dead" headphones after a failed update.

💡

If the headphones connect to only one of the pair, try manually resetting: press and hold the touchpads on both headphones simultaneously for 20 seconds until the indicators flash red.

5. Sound optimization: equalizer, codec and noise cancellation

The sound quality in Xiaomi headphones depends largely on the selected settings. Here is how to improve it:

Equalizer setting

The Mi Earphones app has several pre-profiles available:

• Bass+: amplifies low frequencies (suitable for hip-hop, electronic music).
• Vocals: Raises the average frequencies for better legibility of voice.
• Balance: A neutral profile for most genres.

To manually adjust, tap on Customize and adjust the bands manually. Tip: Do not raise high frequencies (>10 kHz) by more than +3 dB - this can cause distortion.

Codec selection

On Android, you can manually select the codec in Bluetooth settings:

1. Go to Settings → Connected devices → Headphones → Settings (cogs).
2. Select the audio codec.
3. Recommended options: AAC: better balance of quality and stability. LDHC: maximum quality (only for supported models). SBC: versatile, but with less detail.

Noise suppression and transparent regime

ANC models (such as Xiaomi Buds 4 Pro) allow you to adjust the noise reduction level:

• 🌃 Adaptive: automatically adjusts the level depending on the surrounding noise.
• 🚆 Transport: maximum suppression of low-frequency noise (airplane, train).
• 🏢 Office: Suppresses voices and keyboards.

💡

For better ANC effect, make sure the headphones fit tightly to the ears. Use suitable sized earpieces (usually a set of 3-4 pairs).

6.Gestural and voice assistant management

Xiaomi headphones support touch control, but the settings may vary depending on the model. Here are the standard gestures for most devices:

To reassign gestures:

1. Open the Mi Earphones app.
2. Go to the Control or Gestures section.
3. Select an action for each type of touch from the list (e.g., calling Google Assistant or switching ANC modes).

To activate the voice assistant (Google Assistant, Siri or Xiao AI):

• On Android: Enable the resolution for headphones in Settings → Apps → Special Access → Default Assistant.
• On iOS: go to Settings → Siri and Search and add headphones to the list of devices to call Siri.

7. Extension of battery life

The battery in Xiaomi headphones is designed for 300-500 charging cycles, but if used improperly, its capacity can quickly decrease.

• 🔌 Don't discharge completely: plug the case into charging when the headphone charge drops to 10-15%.Full discharge reduces the life of lithium polymer batteries.
• 🌡️ Avoid overheating: Do not leave headphones or case in direct sunlight or near heat sources (e.g., on the dashboard of a car).
• 🔄 Use regularly: If your headphones lie idle for more than 2 weeks, discharge and charge them up to 50% once a month to keep your battery healthy.
• 🚫 Do not use “fast” charging: Xiaomi cases usually support charging to the right level. 5W — More powerful adapters can damage the power controller.

Storage tip: If you don't plan to use headphones for more than a month, keep them in a case with a charge of about 40-60%. Fully charged or discharged batteries degrade faster with prolonged downtime.

⚠️ Warning: If the case stopped charging the headphones, check the contacts for oxidation or debris. Clean them with a cotton swab dipped in alcohol. Do not use metal objects!

8.Reset and flash Xiaomi headphones

If the headphones are unstable even after reset, you may need to flash it back, which is a risky process that is recommended only for advanced users.

Reset to factory settings

For most models:

1. Put both earbuds in the case.
2. Open the case lid.
3. Press and hold the button on the back of the case for 15-20 seconds until the indicator flashes red and white.
4. Close the lid, then remove the headphones - they will be ready for a new connection.

Flashing (for advanced users only)

You'll need to flash it back:

• Windows computer.
• The program nRF Connect (for models on a Nordic chip) or Qualcomm Flash Tool (for Qualcomm chips).
• A firmware file for your model (can be found on forums like XDA Developers or 4PDA).

Warning: Incorrect firmware can turn headphones into a "brick." Before the process, make sure that the firmware file is specifically designed for your model and revision (check the number on the box or in the Mi Earphones app).
