How to connect headphones Xiaomi among themselves: full instruction for all models

Xiaomi’s True Wireless Stereo (TWS) wireless headphones allow you to enjoy wireless music, but sometimes users face a problem: the headphones do not sync with each other. Instead of stereo, only one headphone works, or both connect as separate devices. In this article, we will discuss why this happens and how to properly pair Xiaomi headphones with each other – from basic models (Redmi AirDots) to flagship (Xiaomi Buds 4 Pro).

The synchronization process depends on the model, the firmware version, and even whether the headphones have been used with other devices before, and we'll look at generic methods and nuances for specific lines, and if you just bought the headphones or they "disconnected" after the upgrade, here's the solution.

Why are Xiaomi headphones not paired with each other?

Before we go into the instructions, it is important to understand the causes of the problem, and most often, the problems arise from:

• 🔋 Battery discharge – if one of the headphones sits down, it will not be able to sync.
• 📱 Conflict with previous connection – headphones “remember” the old device and can not switch.
• 🔄 Firmware failure – after updating or resetting settings, re-synchronization is required.
• 🎧 Mechanical damage - ingress of moisture, falls or wear of contacts in the case.
• 📡 Interference from other devices – Bluetooth devices working nearby may interfere with pairing.

80 percent of the time, the problem is solved by resetting the headphones and re-syncing, but if the headphones are new and never connected, maybe they're just not activated. We'll look at the step-by-step steps for different situations.

Preparation for pairing: what to do before the beginning

Before syncing headphones, follow a few mandatory steps:

Charge your case and headphones to 100% | Remove both headphones from the case | Turn off Bluetooth on all devices except the one you're connecting to | Make sure the headphones are clean (the contacts in the case are not oxidized) | Check that the headphones are the same model (you can't sync different versions)

-->

If the headphones have already been used with another smartphone or tablet, you need to “forget” them in the Bluetooth settings on the old device, otherwise they can automatically connect to it, ignoring the new pairing.

• 📲 The phone is enabled Bluetooth 5.0 or later (for stable operation). TWS).
• 🔄 Headphones are no more than 1 meter away from the phone during pairing.
• 🚫 No active VPN Firewalls that block Bluetooth connections.

⚠️ Warning: If one of the headphones flashes red, it means low charge or error. Place it back in the case for 10-15 seconds, then try again.

Universal way to pair headphones Xiaomi (for most models)

This method is suitable for most people. TWS-Xiaomi headphones, including Redmi AirDots (1/2/3 gen), Xiaomi Buds 3/4 Pro, Haylou GT1/GT2 Follow the instructions:

1. Take both earphones out of the case. They should automatically turn on (the indicator blinks).
2. Press and hold the touchpad on both headphones for 5-7 seconds until you hear the beep (or the white/blue light flashes).
3. On the phone, open Settings. → Bluetooth and find a device with your model name (e.g. Redmi) AirDots_R Mi True Wireless).
4. Click on the device you find to connect. After 3-5 seconds, both earbuds should sync (in Bluetooth settings, the status of Connected for stereo will be displayed).

If the headphones are connected as two separate devices (mono), reset:

1. Place both headphones in the case and close the lid.
2. Press and hold the button on the case (if any) for 10-15 seconds until the indicator flashes red and white.
3. Take out the headphones and repeat the pairing.

💡

If the headphones don't respond to pressing, try cleaning the contacts in the case with a cotton swab dipped in alcohol. Oxidation of metal contacts is a common cause of failure.

Features of pairing for popular Xiaomi models

Some models have unique synchronization nuances, and here's a table of instructions for the most common headphones:

For models with active noise cancellation (Xiaomi Buds 4 Pro, FlipBuds Pro) before pairing, it is recommended to disable the ANC in the Mi Earphones application, as this feature may interfere with initial synchronization.

⚠️ Attention: Xiaomi headphones with support LDAC (For example, Buds 4 Pro may not sync with devices on Android 10 and below due to lack of codec support.

What if the headphones are paired, but the sound is only in one?

If only one headphone is running after the connection, the problem may be:

• 🔊 Incorrect Bluetooth settings – the phone recognizes headphones as a mono-device.
• 📵 Synchronization failure: Headphones 'can't see' each other.
• 🎛️ Sound settings – Mono or Left/Right only enabled».

Decisions:

1. On your phone, go to Bluetooth Settings, find your headphones and click on ⚙️ (Make sure you select Stereo (A2DP), Not the phone (HFP).
2. In the Mi Earphones app (if supported by your model), check the Sound → Balance section – move the slider to the middle.
3. Perform Forced Resynchronization: 1. Place both earbuds in the case. 2. Close the lid for 10 seconds, then open. 3. Remove the headphones and wait 20 seconds - they should automatically hide.

How to update the firmware of headphones for stable synchronization

Pairing failures are often caused by outdated firmware, which can be updated through the official Mi Earphones app (available for Android and iOS):

1. Install the app from Google Play or the App Store.
2. Connect the headphones to the phone and open the application.
3. Go to the Firmware Update (if available). If you have an update, follow the instructions on the screen.

Once the firmware update is done, the headphones will automatically reset and require re-pairing. Don't interrupt the process, which can lead to loss of functionality.

⚠️ Warning: If the headphones stopped turning on after the update, place them in a case for 1 hour for a full reboot. If this does not help, contact the service center (controller may fail).

Hardware problems: when pairing is impossible

If none of these things worked, it could be a hardware malfunction.

• 🔌 Damaged contacts in the case – headphones do not charge or sync.
• 🎧 Failure of the Bluetooth module in one of the headphones.
• 💧 Short circuit after moisture is injected (even if the headphones are protected) IPX4/IPX5).

Check it out.

1. Does the charge indicator work on the case (if not, the problem is in the battery or board).
2. Do the headphones respond to touch (if not, sensor failure is possible).
3. Whether there are extraneous sounds (wheezing, crackling) is a sign of damage to the speaker.

If headphones are guaranteed, contact the Xiaomi service center. For self-repair you will need:

• 🔧 A soldering iron and a set of screwdrivers.
• 🛠️ Spare contacts or Bluetooth module (you can order on AliExpress).
• 📖 Disassembly scheme for your model (see forums, for example, 4PDA).

💡

If the headphones stopped synchronizing after falling or getting wet, do not try to disassemble them yourself without experience - this can lead to a complete failure.
