How to synchronize two headphones Xiaomi AirDots 2: instructions with photos and videos

Xiaomi AirDots 2 wireless headphones (also known as Mi True Wireless Earbuds 2) remain among the most popular. TWS-It's a combination of price, sound quality and reliability, but many users are faced with the problem of one of the headphones being unable to sync with the other or refusing to connect to the smartphone. In this article, we will discuss all possible synchronization methods, including forced reset, manual pairing and solving typical errors.

It's important to understand that AirDots 2 is a lead-led system: one headphone (usually the right-hand one) is the main one and connects to the phone, and the second automatically syncs with it. If this process is disrupted, the sound may disappear in one earbud or both devices will be identified as separate gadgets.

Preparing for synchronization: what to check before starting

Before you start setting up, make sure that the problem is not in the trivial things. Here is a mandatory checklist before synchronization:

• 🔋 Battery charge: both earbuds should be charged at least 30%.If the indicator on the case does not burn or flashes red, connect the case to charge for 10-15 minutes.
• 📱 Phone compatibility: AirDots 2 works with Android 5.0 devices+ or iOS 9.0+. On older versions, connection errors may occur.
• 🔄 Disconnect other Bluetooth devices: If other headphones, speakers, or watches are already connected to your phone, turn them off temporarily.
• 🛠️ Clean contacts: check if there is any dirt or oxidation on the metal contacts in the case and on the headphones (especially if they were lying for a long time without using them).

If at least one of the items is not met, the sync may not be correct, for example, when the charge is low, the headphones can automatically turn off a few seconds after connecting, and the phone will “see” them as two separate devices.

Standard synchronization: Connecting to the phone

In 90% of cases, the headphones sync automatically when you first connect, and here's a step-by-step guide for the standard scenario:

1. Take both earbuds out of the case. They should start flashing white lights at the same time (device search indicator).
2. On your phone, turn on Bluetooth and find Mi True Wireless Earphones 2 (or AirDots 2) in the list of available devices.
3. Click on the name of the headphones to pair. After 5-10 seconds, the beep should appear in both headphones, and the indicators will go out (or light up in blue).
4. Check the sound: play music or video. If you hear it in only one headphone, move on to the next section.

If the headphones are not defined as one device, but are displayed separately (e.g. AirDots) 2_L and AirDots 2_R), This means that the synchronization between them is broken, in which case the forced reset will help (see next section).

Forced resetting of headphone settings

If standard synchronization doesn’t work, you’ll need a hard reset, which will bring the headphones back to factory settings and make them re-synchronize with each other, and is suitable for the Xiaomi AirDots 2 of all versions (including AirDots 2 SE and AirDots Pro 2).

Algorithm of action:

1. Put both headphones in the case and close the lid for 5 seconds.
2. Pull them out and hold the touch buttons on both headphones for 15-20 seconds until the lights start flashing red and white alternately.
3. Release the buttons. The headphones will automatically reboot (the indicators will go out, then light up white).
4. Repeat the standard connection (see the previous section).

Once reset, the headphones may not immediately identify as a single device.

• Try connecting to the right earpiece first (it should become the lead).
• If there is sound in only one headphone, put both back in the case for 10 seconds, then pull out and reconnect.

Manual synchronization of headphones with each other

In rare cases, even after reset, the headphones refuse to sync automatically, so you can try to force them to be tied manually.

• 🎧 Both headphones are defined by the phone as separate devices (AirDots) 2_L and AirDots 2_R).
• 🔊 The sound is only in one headphone.
• 🔄 After the reset, the problem persists.

Instructions:

1. Connect the right headphone to the phone (it should become the lead).
2. Remove the left earphone from the case and hold its touch button for 5 seconds until the indicator starts flashing white.
3. Place both headphones side by side (within 10 cm) and wait 10-15 seconds. They should sync automatically (the indicators will light up in blue).
4. If sync is not happening, repeat the steps, but this time hold the button on the right earpiece.

This method works in 70% of cases when automatic synchronization is not available, and if it doesn’t work, check the firmware of the headphones (more on this in the next section).

💡

If the headphones are synced but the sound is interrupted, try turning off the Absolute Volume option in your phone's Bluetooth settings. TWS-headphone.

Synchronization problems: causes and solutions

If none of these methods worked, the problem could be hardware or software failures, and the table below is one of the most common errors and their solutions:

Special attention should be paid to firmware, outdated software can cause synchronization problems, especially after updating the phone's operating system.

1. Put the headphones on the phone.
2. Install the official Mi Home or Xiaomi Wear app.
3. Go to the headphone management section and check for updates.

💡

If the headphones stop syncing after falling or getting moisture, do not try to repair them yourself - this can lead to a short circuit.

Firmware Update: When and How to Do It

The firmware of the Xiaomi AirDots 2 headphones updates automatically when you connect to the Mi Home app, but only if the phone software version is not lower than Android 8.0 or iOS 12.0. If the update does not come, try the following steps:

• 📲 Remove headphones from the list of Bluetooth devices on your phone.
• 🔄 Reboot the phone.
• 🎧 Reconnect the headphones and open the Mi Home.
• 🔍 In the Devices section, find AirDots 2 and check for updates manually.

If the update is suspended during the loading stage:

⚠️ Warning: Don't turn off Bluetooth or put your headphones in the case during the upgrade, which can cause the firmware to break, and the headphones will stop turning on. If it's been more than 10 minutes, restart your phone and try again.

After a successful upgrade, the headphones will automatically restart and have to be reconnected. If the sync problem persists, try resetting again (see Section 3).

Alternative ways of connecting

If standard methods don’t work, you can try non-obvious solutions that sometimes work:

• 📵 Connecting via another phone: Try syncing your headphones with another device (like a tablet) and then returning them to your main phone.
• 🔌 Charging cable usage: Some users note that connecting the case to charging during synchronization helps to “wake up” the headphones.
• 🎵 PC audio playback: connect your headphones to your computer (via Bluetooth) and run the test sound. Sometimes this resets synchronization errors.

It is also worth checking the sound settings on the phone:

• Open Settings → Sound → Bluetooth sound quality.
• Select SBC (Standard Codec) over AAC or aptX – this can fix connectivity issues.

💡

If the headphones are connected, but the sound is only in one, try in Bluetooth settings to turn off the option "Mono-audio" (if any).
