How to connect two headphones Xiaomi AirDots 2 with each other: 5 proven ways

Xiaomi AirDots 2 wireless headphones (also known as Redmi AirDots 2) are popular for their affordable price and sound. However, many users face the problem when one headphone stops working or does not sync with the second. In this article, we will analyze all possible causes of disconnection of the headphones and give step-by-step instructions for reconnecting them, from simple reset to manual synchronization through special button combinations.

The problem can arise after a firmware update, prolonged inactivity or mechanical damage. It is important to understand that AirDots 2 uses a master/subject protocol: one headphone (usually the right one) is the main one and connects to the phone, and the second one is the auxiliary one that connects to the first one. If this process is disrupted, the sound goes only in one earphone or disappears altogether. Next, you will find unique methods for pair recovery that are not described in the official documentation of Xiaomi.

Before you start syncing, make sure the problem isn’t related to a dead battery or mechanical damage. Often users try to connect the headphones when one of them is completely discharged – this leads to connection errors.

• 🔋 Check the charge level of both headphones through the indicator on the case (should burn). 2-3 If there is no indication, charge the devices at least 30 minute.
• 🎧 Look at the contacts on your headphones and in your case: they should be clean, free of oxidation or contamination.

2. Remove the headphones from the case and hold the buttons on both for 15 seconds until the indicators start flashing red and white alternately.
3. Put the headphones back in the case and close it. After 5 seconds, remove them - an automatic synchronization process should occur (the indicators will flash white synchronously).

• 🔄 Get both earphones out of the case.
• 🎵 Press and hold the button on the right earphone for 5 seconds until you hear the beep.
• 🔊 Then hold the button on the left earphone for 8 seconds until the indicator starts flashing purple.
