How to sync Xiaomi headphones with each other: instructions for all models

Xiaomi wireless headphones are some of the most popular smartphone accessories due to their combination of price, sound quality and functionality. However, many users have difficulty syncing two headphones together to create a stereo effect or share music. In this article, we will discuss how to pair Xiaomi, Redmi or Haylou headphones correctly, which models support this feature, and what to do if synchronization does not work.

It’s important to understand that not all Xiaomi headphones support connecting two devices to the same sound source at the same time. For example, the budget Redmi AirDots of the first generation can only work in mono mode, while the Xiaomi Mi True Wireless Earphones 2 or Haylou GT6 support Dual Mode. There are also nuances with the firmware: some headphones require an update for proper synchronization. We will take a closer look at all these points.

What Xiaomi headphone models support synchronization with each other

Before you try to sync your headphones, make sure your model supports this feature. Here is a list of popular devices with the ability to stereo or dual mode:

• 🎧 Xiaomi Mi True Wireless Earphones 2 (and newer versions)
• 🎧 Xiaomi Mi AirDots Pro 2/Pro 2s
• 🎧 Redmi AirDots 3/3 Pro (Dual Mode only)
• 🎧 Haylou GT1/GT2/GT6 (full synchronization support)
• 🎧 Xiaomi FlipBuds Pro (with firmware at least 1.4.0)

Budget models like the Redmi AirDots (first generation) or Mi Basic don’t usually support synchronizing two headphones in stereo mode. If your model isn’t listed, check the specifications on Xiaomi’s official website or instructions.

Synchronization of headphones can work differently depending on the model:

• 🔹 Automatic synchronization (earphones are connected immediately after extraction from the case).
• 🔹 Manual synchronization (requires button pressing or application use).
• 🔹 Through an app (e.g. Mi Earphones or Haylou Fun).

Preparation of headphones for synchronization: reset and charge check

Before you sync your headphones, you have to reset them to the factory settings, which is especially important if they've been connected to another device or are not working smoothly. The reset procedure varies depending on the model, but the overall algorithm is as follows:

1. Place both headphones in the charging case and close the lid.
2. Open the lid and hold the button on the case (or the touchpad on the headphones) for 10-15 seconds until the indicator starts flashing red and white.
3. Remove the headphones from the case - they should automatically enter the pairing mode (the indicator flashes white).

If the lights don't flash or the headphones aren't detected by the phone, check the charge level. Minimum charge for synchronization is 30%, otherwise the process may be interrupted. Also make sure the case is charged: some models (such as the Haylou GT6) require at least 50% of the charge of the case for stable operation.

⚠️ Warning: If one of the headphones doesn't blink or sound after reset, try clearing the contacts on the headphones and in the case with a dry cotton swab. Dust or oxidation can block charging and synchronization.

Synchronization of headphones Xiaomi through the smartphone: step-by-step instructions

The easiest way to connect headphones is to use a smartphone on Android or iOS. The algorithm is the same for most models:

1. Open Settings → Bluetooth on your phone and turn on device search.
2. Remove both earphones from the case. They should appear in the list of available devices as a single device (for example, Mi True Wireless Earphones 2_L and Mi True Wireless Earphones 2_R or simply LE_Mi_TWS).
3. Click on the headphone name in the list. If synchronization is successful, you will hear an audible beep in both headphones, and in the Bluetooth settings, one device will appear (for example, Mi True Wireless Earphones 2).

If the headphones are displayed as two separate devices, it means that they are not synchronized.

• 🔄 Return the headphones to the case and repeat the reset procedure.
• 📱 Remove them from the list of associated devices in Bluetooth settings.
• 🔋 Check the charge (sometimes low battery levels interfere with synchronization).

On some models (such as the Haylou GT6), you need to manually synchronize:

1. Remove both earphones from the case.
2. Twice touch the touch panel on the right earpiece.
3. Wait until the indicators start flashing synchronously (usually this takes 5-10 seconds).

💡

If the headphones don't sync, try connecting them to another smartphone or tablet, and sometimes the problem is the Bluetooth cache on the main device.

Use of branded applications for synchronization

Some Xiaomi headphone models require a special application to adjust the dual mode.

• 📱 Mi Earphones for Xiaomi Mi True Wireless Earphones.
• 📱 Haylou Fun is for Haylou headphones.
• 📱 Redmi Earphones for the Redmi AirDots line.

Let’s take a look at the Haylou Fun app:

1. Download and install the app from Google Play or the App Store.
2. Connect your headphones to your phone via Bluetooth (even if they are not synced).
3. Open the app and select your headphone model.
4. Go to Dual Mode or Stereo Mode and follow the instructions on the screen.

In the Mi Earphones app, the path can look like this: Settings → Connection Mode → Stereo. Once this mode is activated, the headphones automatically sync when the next connection is made.

⚠️ Warning: If the app doesn't have Dual Mode option, it means your model doesn't support syncing two headphones in stereo mode. Check compatibility on the official website.

Solving synchronization problems: frequent errors and fixing them

If Xiaomi headphones don’t sync, the reasons may be as follows:

• 🔋 Low battery power (less than 30%) Charge your headphones and case.
• 📵 Interference from other devices. Turn off nearby Bluetooth devices (columns, smartwatches) that are working.
• 🔄 Outdated firmware. Update your headphones through your proprietary app.
• 📱 Bluetooth problems on your phone. Reboot your smartphone or reset your Bluetooth settings.

Let’s take a closer look at the most common mistakes:

1. Headphones are connected as two separate devices

It means they're not synchronized.

• Put the headphones back in the case.
• Hold the button on the case for 10 seconds until the indicator starts flashing red and white.
• Remove the headphones and reconnect.

2. One earpiece doesn't make a sound.

Possible causes:

• The headphone is discharged (check the charge indicator).
• The headphone is not synchronized with the main one. Try resetting.
• In the Bluetooth settings of the phone, you've got mono mode. Switch to stereo.

3.The headphones are constantly disconnecting

This may be related to:

• Interference from other wireless devices (Wi-Fi, microwaves).
• Outdated headphone firmware (update through the app).
• Damage to one of the headphones (check on another device).

How to update the firmware of Xiaomi headphones for correct synchronization

Outdated firmware is one of the main causes of synchronization problems, and the manufacturer regularly releases updates to fix connection errors to update the headphones:

1. Install a branded app (Mi Earphones, Haylou Fun, etc.).
2. Connect the headphones to the phone via Bluetooth.
3. Open the app and go to the Firmware Update or Firmware Update section.
4. If an update is available, click Update and wait for the process to complete (don’t turn off the headphones!).

Xiaomi Mi True Wireless Earphones 2:

Mi Earphones → Settings → Update firmware → Check updates

For the Haylou GT6:

Haylou Fun → Device → Software Update → Download and Install

⚠️ Warning: Don't interrupt the upgrade process! If the headphones turn off during firmware, they may stop turning on. In this case, you will need to reset through the service menu (the instructions are usually on the Xiaomi forums).

💡

Updating the firmware often solves synchronization problems, especially if the headphones previously worked normally and then stopped connecting.

Alternative ways of synchronization: if nothing helps

If the standard methods don’t work, try alternatives:

1. synchronization through another device

Sometimes the headphones sync with the iPhone but don't want to work with an Android smartphone (or vice versa). Try connecting them to another phone, tablet, or even a laptop. If the sync is successful, put the headphones back in the case, reset the settings, and try connecting them to the main device.

2.Use of Developer Mode (for Android)

On some smartphones, Xiaomi or Redmi helps to turn on the developer mode and reset Bluetooth settings:

1. Go to Settings → About Phone and tap the MIUI version 7 times to activate the Developer Mode.
2. Back to Settings → Additionally. → For developers.
3. Find the Bluetooth Reset option and activate it.
4. Reboot your phone and try to reconnect the headphones.

Manual pairing through codes

Some models (e.g. Haylou GT1) support manual synchronization via service commands.

1. Connect one earphone to the phone.
2. Open the headphone app and find the Advanced Settings section or Service features.
3. Enter the synchronization code (usually 5555 or 0000).
4. Wait until the second headphone is automatically connected.
