How to Connect Two Xiaomi Wireless Headphones to Each Other: A Complete Guide to 2026

Why Xiaomi Headphones Aren’t Synced with Each Other and How to Fix It

Xiaomi wireless headphones are some of the most popular TWS-The combination of price, sound quality and functionality is a common problem for many users, however, when left and right headphones do not connect to each other, work separately or one of them does not respond to the on. This problem is typical for all lines: from budget Redmi AirDots to flagship Xiaomi Buds 4 Pro.

In 90% of cases, the fault is not due to a hardware defect, but to an incorrect connection sequence or firmware failure. The manufacturer rarely mentions this in official instructions, but there is a universal synchronization algorithm that works for most models. In this article, we will analyze step-by-step actions for different versions of headphones, consider typical errors and give recommendations for troubleshooting.

It's important to understand that the process of connecting the headphones to each other (pairing) and connecting them to the sound source (smartphone, laptop) are two different steps. The first is automatic when removed from the case, but sometimes requires manual reset. The second depends on the Bluetooth protocol of your device. We'll focus on the first step, synchronizing the headphones with each other.

Preparing for synchronization: what to do before connecting

Before you start pairing headphones, make sure that the basic conditions are met:

• 🔋 Battery charge: both earphones and case should be charged at least 30.
• 📱 Turn off Bluetooth on all devices that your headphones have previously connected to, eliminating conflicts when forming a new pair.
• 🧹 Clean the contacts: wipe the metal contacts on your headphones and in your case with a dry wipe.Oxidation or contamination can disrupt charge and communication.
• 🔄 Update the firmware (if available). For Xiaomi Buds 3 Pro and newer models, check the relevance of the software through the Mi Home app or Xiaomi Earbuds.

If you've tried to plug in your headphones before and you've encountered an error, do a full reset.

1. Place both headphones in the case and close the lid.
2. Press and hold the button on the case (usually located behind or below) for 10-15 seconds until the indicator flashes red and white.
3. Open the lid and wait for the automatic reboot (the indicators will go out and light up again).

💡

For Redmi AirDots 2 and Xiaomi Air 2 SE models, the reset is performed by holding the touchpad on both headphones simultaneously for 8 seconds.

Universal instruction: how to connect two Xiaomi headphones between each other

The synchronization algorithm is the same for most models, but there are nuances for specific lines. Below is a step-by-step instruction for the standard case:

1. Remove both headphones from the case and wait until they turn on (indicators will start flashing).
2. Place the headphones back in the case and close the lid for 5 seconds.
3. Remove the headphones. They must automatically connect to each other (the indicators will light up at the same time and start flashing in unison).
4. If synchronization does not occur, press and hold the touchpad on the right earphone for 5 seconds until you hear the beep.
5. Repeat the action for the left earpiece, and then they need to connect.

For visual control of the process, pay attention to the light indicators:

Synchronization Features for Popular Xiaomi Models

Some models require specific actions to connect, and the following are the instructions for the most common lines:

Redmi AirDots (1-3 generation) and AirDots S

These models often lose communication after a firmware update.

1. Remove the headphones from the case and wait for the automatic shutdown (after 30 seconds).
2. Put them back in the case, close the lid.
3. Press the button on the case 3 times in a row (with an interval of 1 second).
4. Get your headphones out – they should sync for 10 seconds.

Xiaomi Buds 3/3 Pro/4 Series

For these models, an advanced algorithm with Bluetooth 5.2 support is used:

• 🎧 Activate the pairing mode by holding the touch panel on any headphone for 3 seconds.
• 🔗 Headphones will automatically find each other within 5 seconds (sound signal will confirm the connection).
• 📱 Connect them to your phone via Bluetooth menu – the list will appear one device Mi True Wireless.

Xiaomi FlipBuds and FlipBuds Pro

These headphones have a mechanical switch on the case:

1. Turn the switch to the ON position (if it was turned off).
2. Open the case cover - the headphones will turn on automatically.
3. Press and hold the touchpad on the right earpiece until the white light flashes.
4. Repeat the action for the left earpiece – they synchronize for 3 seconds.

Typical errors and their solutions

Even if you follow the instructions correctly, you can have some problems, and let's look at the most common problems and how to fix them:

⚠️ Note: If the headphones were previously connected to an iOS device, they can “remember” the profile AAC and conflict when connecting to Android. In this case, reset through the Xiaomi Earbuds app (section "Forget the device").

• 🔴 One earphone won't turn on: Check if the button on the case is stuck (a frequent problem in Redmi AirDots 2). Try to remove the earphone and gently press the contacts inside the case.
• 🔄 Constant reboot: Most likely, the firmware has gone down. Connect your headphones to your PC via Bluetooth and update the software via the Mi Bluetooth Tool (the official Xiaomi utility).
• 🎵 The sound is only in one headphone: This indicates incomplete synchronization. Force the phone's Bluetooth settings to shut down and reconnect.
• 📱 Phone can't see headphones: Make sure your phone is on Bluetooth 5.0+ (Older smartphones may need an adapter).

If neither method worked, check the headphones on another device. If the problem persists, it could indicate a hardware defect (e.g., damage to a Bluetooth antenna in one of the headphones), in which case, contact the service center - under guarantee, such repairs are usually free.

💡

Most synchronization problems are solved by sequence: reset → case reset → re-extract headphones. Don't miss steps!

How to check the quality of synchronization

Once the headphones are successfully connected, you need to make sure that the connection is stable.

1. Play the test sound in stereo mode (e.g. YouTube or Spotify) and move around the room, and the sound should remain synchronized.
2. Check the latency: run the video and pay attention to the synchronization of sound and image. For the Xiaomi Buds 4 Pro, the latency should be less than 100 ms.
3. Use the Xiaomi Earbuds app for diagnostics: Open the Device → Headphone Status tab. Check the charge level of each headphone separately. Make sure that the Connection section displays stereo mode.

For advanced users: Android can use the hidden developer menu to check the quality of the Bluetooth connection. Activate it by clicking 7 times on the Build Number in the phone settings, then go to Settings → System → Developer → Bluetooth Monitor. This shows signal level (RSSI) and connection stability.

💡

If one of the headphones has a quieter sound than the other, check the balance settings in Settings → Special features → The balance of stereo sound on your smartphone.

Additional settings to improve communication

If the headphones are synchronized, but the connection is unstable (breakdowns, noise, delays), try the following settings:

• 📶 Change the Bluetooth codec: In Android: Settings → Bluetooth → Settings (cog next to headphones) → Codec, choose. AAC for better sound quality or SBC stability.
• 🔋 Turn off power saving for Bluetooth: Go to Settings → Battery → Energy conservation → No restrictions.Add the Xiaomi Earbuds app to exceptions.
• 🔄 Update your headphone firmware: Open the Mi Home or Xiaomi Earbuds app. Go to Software Update and follow the instructions.

For models with LDAC support (e.g. Xiaomi Buds 4 Pro), it is recommended to use the 990 kbps LDAC codec for maximum sound quality, but only if your smartphone supports this standard (check in the device specifications).

⚠️ Note: If you use Windows or macOS headphones, turn off Absolute Volume in Bluetooth settings. It can cause audio distortion at high volume.
