How to combine two headphones Xiaomi Redmi in one pair: the complete guide

A pair of Xiaomi Redmi wireless headphones is a convenience and freedom of movement, but sometimes users face a problem: one headphone stops working, does not sync with the other or does not even detect the smartphone. Most often this happens after resetting, battery discharge or accidental button pressing. In this article, we will analyze all the ways to pair two Xiaomi Redmi headphones, including forced synchronization, factory reset and fault diagnosis.

It's important to understand that the connection process may vary depending on the model: Redmi AirDots, Redmi Buds 3/4, Redmi Earbuds S or newer versions. However, the general principle remains the same. If you first encounter this problem, don't panic: 90% of the time, the headphones can be paired without going to the service center.

Before you start the instructions, make sure that both headphones are charged at least 30% (the indicator should flash red or white when extracted from the case). Also check that your smartphone supports Bluetooth 5.0 or later - this is critical for the stable operation of the latest Redmi Buds.

Why Xiaomi Redmi headphones don’t pair together?

Problems with syncing two Xiaomi Redmi headphones usually occur for several reasons.

• 🔋 The battery of one of the headphones is discharged (even if the second one is charged).
• 🔄 Firmware failure after incorrect update or interrupted connection.
• 📱 Conflict with Bluetooth devices in smartphone memory (for example, if the headphones were previously paired with another phone).
• 🛠️ Mechanical damage to contacts in the case or on the headphones themselves.
• 🔊 Activation of monoconnection (one earphone mode) that blocks synchronization.

Sometimes the problem lies in the software of the smartphone, for example, Xiaomi/Redmi/Poco with a MIUI shell can experience bugs when connecting devices via Fast Pair (fast pair), in which case it will help to reboot the phone or reset Bluetooth settings.

⚠️ Attention: If one of the headphones does not respond to button presses and does not charge at all, the problem may be a plume break or a battery failure.

Method 1: Standard connection via case

The simplest method is forced synchronization via a charging case, which works for most Redmi AirDots/Buds models and does not require additional manipulation of the smartphone.

Instructions:

1. Place both headphones in the case and close the lid for 10-15 seconds.
2. Open the case and remove both earbuds. They should automatically turn on (indicators flash white or red).
3. Press and hold the touchpad on both headphones simultaneously for 5-7 seconds until the indicators start flashing red and white (mating mode).
4. Return the headphones to the case and retrieve them in 5 seconds. They should pair automatically (the indicators will light up in blue or purple).

If after these actions, the headphones are still not synchronized, try resetting their settings (more about this in the next section).

Method 2: Resetting headphones to factory

If standard synchronization doesn't work, the next step is to completely reset the settings, which removes all the connections you've saved and returns the headphones to their original state.

For different models Xiaomi Redmi process may be slightly different, but the overall scheme is as follows:

After discharge:

1. Return the headphones to the case and close the lid for 30 seconds.
2. Take them out and wait for automatic synchronization (the indicators should be blue).
3. Connect the headphones to the smartphone via Bluetooth (in the list of devices will appear one name, for example, Redmi Buds 4).

⚠️ Note: On Redmi Buds 3 Pro and later, the reset may require you to connect to the Mi Earphones app. If the headphones do not sync after the reset, install official software from Xiaomi.

Method 3: Manual Bluetooth connection (if automatic synchronization is not working)

If the headphones don't pair up even after resetting, you can try forcefully pairing them through a smartphone, which works when one headphone is identified by the phone and the other isn't.

Instructions for Android:

1. Open Settings → Bluetooth and remove all Xiaomi Redmi devices from the paired list.
2. Take both headphones out of the case and wait until they start flashing (search mode).
3. In the list of available devices should appear two separate headphones (for example, Redmi Buds). 4_L and Redmi Buds. 4_R).
4. Connect first to the right earpiece ( R), then to the left earpiece ( L).
5. After connecting both headphones should automatically pair (on the Bluetooth list will remain one device).

The process is similar for iPhones, but additional confirmation of each earbud connection may be required.

💡

If only one headphone is displayed in the Bluetooth list, try restarting your smartphone or turning off power saving mode – it can block device search.

Method 4: Use the official Mi Earphone app

For Redmi Buds 3 Pro, Redmi Buds 4 and later, you must install the Mi Earphones app (available on Android and iOS), which not only simplifies configuration, but also allows you to:

• 🔧 Update the firmware of headphones.
• 🎛️ Set up sensor control.
• 🔊 Check the charge level of each headphone separately.
• 🔄 Forced to sync headphones if they are "disconnected".

How to use the application for synchronization:

1. Download Mi Earphones from Google Play or App Store.
2. Connect any of the headphones to your smartphone via Bluetooth.
3. Open the app and select your headphone model.
4. Go to Settings → Headphone Synchronization and follow the instructions on the screen.

If the app doesn't see headphones, try:

• 📱 Reinstall Mi Earphones.
• 🔄 Reboot the smartphone and headphones (reset via case).
• 📋 Check if your model supports the application (the list of compatible devices is available on the official website of Xiaomi).

Problems after successful synchronization: what to do?

Even if you manage to pair the headphones together, there may be additional problems:

If after synchronization the sound is only in one headphone, check:

• 🎧 Sound balance in smartphone settings (Settings) → Sound. → Stereo balance).
• 🔊 Mono/stereo mode in Mi Earphones (should be selected stereo).
• 🛠️ Physical damage to the headphone (try connecting it separately).

💡

If after all the manipulations, the headphones still do not work in pairs, the problem may be a hardware malfunction (for example, a Bluetooth module in one of the headphones is damaged), in this case, contact the Xiaomi service center.

Frequent errors when connecting headphones Xiaomi Redmi

Many users make common mistakes that prevent successful synchronization.

• 🚫 Pressing the headphone buttons in the case – this can lead to the reset of only one device.
• 🚫 Connect headphones to different smartphones at the same time – it knocks their settings.
• 🚫 Use a non-original charging cable – it may not provide enough current for synchronization.
• 🚫 Interrupt the mating process (for example, remove the headphones in the case until the flashing of indicators is completed).

Another common mistake is ignoring firmware updates, Xiaomi regularly releases patches to fix plugged-in bugs to check firmware relevance:

1. Open the Mi Earphones app.
2. Go to the Firmware Update section.
3. If a new version is available, connect the headphones to the charger and wait for the process to be completed.

⚠️ Warning: Don't interrupt the firmware update! this can cause the headphones to be completely inoperable and require flashing over the PC.
