Basic checks: what to do first

Before you dig deeper, make sure that the problem isn't the obvious, and these steps take less than a minute, but solve up to 30 percent of the cases.

Check the charge of the headphones and the case. If the indicator on the case does not burn or flashes red, connect it to the charger on the case. 10–15 Xiaomi Airdots headphones can turn off when the charge level is below 5%, Even if the light is still on white, use the original cable or the support adapter. 5V/1A — weak current may not start charging.

Make sure the headphones are properly placed in the case. The contacts on the back of the headphones should fit tightly to the metal connectors inside the compartments. If contact is disturbed (for example, due to dirt or deformation), the headphones will not charge and sync. Wipe the contacts with a cotton swab dipped in alcohol.

• 🔋 Case Charge: Connect to the network, wait for a stable white indicator.
• 🎧 Headphone charge: Put them in the case for 30 seconds - the indicators should flash red (discharge) or white (charged).
• 📱 Bluetooth on your phone: Turn on/off the plane mode for 10 seconds, then activate Bluetooth again.

⚠️ Warning: If the headphones do not respond to the placement in the case (do not blink, do not charge), the problem may be in the power controller.

Also check if the headphones are connected to another device. Xiaomi Airdots remember up to 8 devices, and if they were previously paired with a laptop or tablet, can automatically switch to them.

How to reset:

1. Put both headphones in the case and close the lid.
2. Wait until the headphones go out (this means they are turned off).
3. Press the touchpad on both headphones simultaneously for 15-20 seconds. On Redmi Airdots and Mi True Wireless, this is a round area on the body.
4. The indicators will first light up in red, then flash red and white (purple on some models), a signal of successful reset.
5. Open the case cover – the headphones should automatically turn on the pairing mode (blinking white light).

After reset, connect the headphones to the phone again:

1. On the phone, open Settings → Bluetooth.
2. Click Add Device and select Mi True Wireless (or your model) from the list.
3. Confirm the pairing. Some models will need to enter PIN-code.

⚠️ Attention: If one of the headphones does not connect after reset (for example, only the right one works), the problem may be in synchronization between the headphones.

3.Chronization problems: One earphone is not working

A common situation is that after a firmware reset or update, the left or right earphone doesn't connect, although the second one works normally, which means that the synchronization between them is disrupted, and you can restore it in two ways.

Method 1: Forced synchronization through the case

2. Wait 30 seconds, then open the lid. The headphones should automatically sync (the indicators flash white).
3. If synchronization does not occur, press the touch panels on both headphones for 10 seconds until the indicators start flashing red and white.
4. Close the case cover for 10 seconds, then open it again.

Method 2: Manually connect the second headphone (if not automatically synchronized):

1. Connect to the phone working headphone (for example, right).
2. Take out the second headphone from the case and press the touch panel on it for 5 seconds until the indicator starts flashing white.
3. On your phone in Bluetooth settings, click on the connected headphone and select Add left/right device (the item name may differ).

If none of these things worked, the problem might be a hardware malfunction on one of the headphones.

• Try connecting each headphone separately to the phone (if the model supports mono-connection).
• See if the problem headphone is charged in the case (the indicator should burn red when discharged).
• Check if the touchpad responds to touch (for example, when controlling playback).

4. Update of the firmware headphones Xiaomi Airdots

Outdated firmware is one of the main reasons for an unstable connection, especially after an Android or iOS update. Xiaomi regularly releases patches to fix plug-in bugs, but they don't install automatically.
