Xiaomi Mi wireless headphones (including Mi True Wireless Earbuds Basic 2, Mi AirDots, Mi Air 2, and others) have become popular due to a combination of price and quality. However, many users face a common problem: one of the headphones stops working — does not connect, does not make sound or shuts down after a few seconds. The reasons can be either software (firmware failure, pairing error) or hardware (contact damage, battery discharge).
In this article, we’ll look at all the possible reasons why one Xiaomi Mi headphone doesn’t work, and offer step-by-step solutions, from simple (reboot, reset) to complex (disassemble and clean contacts), and you’ll learn how to distinguish hardware from software failure and when to contact the service center. If your headphones are still warranty, some actions may cancel it, we’ll warn you about this in advance.
So for convenience, we've put the data into a table of typical symptoms and solutions, and we've added interactive widgets to help you diagnose the problem quickly, and let's start with the simplest thing: checking the basic settings.
1. Checking basic settings: what to do first
Before disassembling the headphones or carrying them for repair, make sure that the problem is not in the settings of the smartphone or the headphones themselves. Often one Xiaomi Mi headphone does not work due to trivial pairing errors or a Bluetooth failure.
Follow this algorithm:
Check compatibility.
Xiaomi Mi
iOS
Android
If the problem persists after the firmware update, try connecting the headphones to another device. If both headphones work normally on the second device, the problem is in your smartphone (maybe you need to reset to factory settings).
💡
Before updating the firmware headphones make sure that they are charged at least 50%. interruption of the upgrade process can lead to complete failure of the device.
5. Hardware breakdowns: when without repairs can not do
If all software methods have been tried, but one Xiaomi Mi headphone still doesn’t work, it’s likely a hardware malfunction.
- 💧 Moisture infestation - corrosion on the board, the headphone works intermittently or does not turn on.
Some problems can be repaired by yourself (such as cleaning contacts or replacing the battery), but most require professional repair.
⚠️ Attention: Disassembling headphones Xiaomi Mi without experience is fraught with damage to plumes or microphone. the body of most models is glued, and if you do not open it carefully, you can damage the speaker or Bluetooth antenna.
Cost of repairs in service centers:
- Replacement of the battery - from 800 to 1500 rubles.
- Repair of Bluetooth module - from 1200 to 2000 rubles.
- Replacement of the speaker - from 1000 to 1800 rubles.
- Cleaning from moisture - from 500 to 1000 rubles (without a guarantee of recovery).
If headphones are warranty, do not disassemble them yourself - this will void warranty obligations. Contact the official Xiaomi service center with a check and a box.
6. Alternative solutions: what to do if repair is not advisable
If it costs more to repair than buying new headphones, or your model is outdated (such as the first-generation Mi AirDots), consider alternatives:
- 🎧 Use the headphones separately — many Xiaomi Mi models support mono mode:
Update the model
Xiaomi Buds 4
Redmi Buds 5
If you decide to buy a new headphone separately, make sure it is compatible with your model. For example, the Mi Air 2 right and left headphones are not interchangeable with the Mi AirDots Pro, even if they look similar on the outside.
💡
Before buying a separate earphone, check its serial number or model on the box. Incompatible headphones will not synchronize with each other.
7. Prevention: how to prolong the life of wireless headphones
To avoid problems with one broken Xiaomi Mi headphone, follow these guidelines:
- 🧼 Clean contacts regularly – use a dry soft brush or cotton swab with alcohol (at least 1 time per month).
Also avoid using headphones in extreme temperatures (below -10°C or above +40°C) - this can damage the battery and electronic components.
