The situation when suddenly stops working one headphone Xiaomi Airdots 2, causes a natural irritation, especially if the device was used without complaints. Users often face the fact that the right or left module simply does not give signs of life: the indicator does not light up, there is no sound or no pairing with the smartphone. In most cases, the problem lies not in the fatal breakdown of electronics, but in a banal violation of contact or software failure that can be eliminated on your own.
Before you carry the gadget to the service center or buy a new pair, it is worth conducting a thorough diagnosis. TWS-Headsets have autonomous power supplies and transmitters in each ear, making it more likely that they will become out of sync. Statistics show that more than 80 percent of all calls for a broken module are solved by simply cleaning or restarting.
In this article, we will discuss all possible reasons for the failure of one of the Xiaomi Mi True Wireless Earbuds Basic 2 headphones. We will look at both software recovery methods and physical ways to reanimate the device. It is important to act consistently to eliminate simple errors before moving to complex manipulations.
Diagnostics of charging and contact problems
The most common reason why one Xiaomi Airdots 2 earphone doesn't turn on is because it doesn't have a battery charge. The design of the case is that the modules have to fit tightly to the contact pads to start the charging process. If you take the headset out of the case and one of them doesn't catch a red light, then the electric current doesn't go to the battery.
Often the problem is oxidation of contacts or dust. Charging pins on the headphones themselves and inside the case eventually become covered with a microscopic layer of oxides or earwax, which creates high resistance. Even the thinnest film of dirt can block charging, making the device appear completely dead. Visually, this can be invisible, so you need to look carefully in good light.
💡
Use a cotton swab, slightly soaked in alcohol, to gently wipe the golden contacts, let the alcohol completely evaporate before placing the earpiece in the case.
It's also worth checking the mechanical fit. Sometimes a silicone fitting or a factory defect prevents the module from fully diving into the niche of the case, and as a result, the magnet holds the device, but there's no contact. Try to press the headphone slightly in the case - if the indicator flashed, then the problem was in the bad fit.
⚠️ Note: Do not use metal objects (needles, pins) to clean the contacts inside the case.This can lead to short circuit and the final failure of the charging case.
Program reset and re-synchronization
If the charging is okay, but one headphone Xiaomi Airdots 2 is not working, there is probably a failure in the communication protocol between the modules. Left and right channels must work in pair, and if the communication between them is lost, the sound will only go to one or not appear at all.
The reset procedure requires a precise sequence of actions. First, remove the device from the Bluetooth list on your smartphone by finding Mi True Wireless EBs Basic 2 and selecting "Forget the device." Then place both earbuds in the case, but do not close the lid. You will need to pinch the touch areas on both modules simultaneously.
