Xiaomi wireless headphones disconnected – what to do to restore communication?

Why are Xiaomi’s wireless headphones losing touch with each other?

The situation when one of Xiaomi’s wireless headphones suddenly stops working and the second one continues to play sound is familiar to many users, the causes can be due to software failures and hardware malfunctions, most often due to:

Battery discharge in one of the headphones (even if the indicator shows charge, the contact could oxidize);

failure of synchronization between left and right modules after updating the firmware or incorrect connection to the new device;

mechanical damage (for example, moisture entering the charging connector or falling from a height);

Bluetooth profile conflict, when headphones β€œforget” each other after connecting to several gadgets.

In 80% of cases, the problem can be solved independently without going to the service center, and below we will analyze step-by-step instructions for different models - from the budget Redmi AirDots to the flagship Xiaomi FlipBuds Pro.

Before you start to do complex manipulations, make sure that the problem is not in trivial things.

Reboot your smartphone/laptop to which the headphones are connected

Try to connect to another device (such as a tablet)

Clean the charging connectors from dust and oxidation-->

If the headphones are still out of sync after this, move on to the next step. Note: some models (such as the Xiaomi Buds 3 Pro) have an automatic reconnect function that can be triggered with a delay of up to 30 seconds.

⚠️ Warning: Don't try to disassemble the headphones yourself - this will deprive you of warranty. Inside the case, glue joints and miniature plumes are used, which are easily damaged.

7. Alternative ways of connecting (if nothing helps)

If you can not restore synchronization between headphones, you can try alternative connection schemes:

Method 1: Connecting separately

Some models (e.g. Buds 3T) support independent left and right earphone connection.

  1. Remove the earphone from the case and hold the touchpad for 5 seconds until blinking white.
  2. Connect it as a separate device via Bluetooth.

Cons: the sound will be mono, and the functionality is limited (for example, no noise maker will work).

Method 2: Using a Bluetooth adapter

If the headphones only detect one device (like a smartphone) but don’t sync with another (laptop, TV), you can use a Bluetooth transmitter (like the Xiaomi Bluetooth Audio Receiver). Connect it to the sound source and then pair it with the headphones.

⚠️ Note: With such a connection, there may be a delay of up to 200-300 ms, which is critical for watching video.
