Xiaomi Mi True Wireless Earbuds Basic 2 (or Airdots 2) are some of the most popular budget headphones TWS-They're not immune to breakage, but most people have problems when the right earbud doesn't work, doesn't connect to the phone, doesn't make a sound, shuts down after a few seconds, or doesn't respond to charging at all. In 80% of cases, the problem can be solved independently without contacting the service center.
In this article, we’ll look at all the possible causes of a right earbud malfunction, from software failures to physical damage, and give you step-by-step diagnostic and repair instructions. If you’re unsure of your abilities, skip the disassembly sections and focus on software methods — they work in 6 out of 10 cases.
Why Xiaomi Airdots’ right earphone doesn’t work 2: the main reasons
Before you try to fix your headphones, it's important to understand what exactly went wrong, and the reasons can be divided into three categories:
- 🔋 Power problems - battery discharged, contacts of the charging case oxidized, plume damaged.
- 📱 Software failures – synchronization error between headphones, outdated firmware, conflict with Bluetooth on a smartphone.
- 🔧 Hardware breakdowns - damaged speaker, soldered contact, got moisture.
The most common situation is that the right earbud doesn't connect to the left (or vice versa), which is due to a failure in the TWS (True Wireless Stereo) synchronization protocol, in which case both earbuds may be working, but they don't "see" each other, and less often the problem lies in the Bluetooth chip inside the right earbud, which can overheat or fail after a fall.
If the earphone is turned on but not making sound, either the speaker (check for mechanical damage) or the audio channel in the smartphone settings is to blame. Sometimes the sound disappears after updating the phone's firmware, in which case the reset of the Bluetooth settings will help.
Diagnosis: how to determine the cause of the breakdown
Before disassembling the headphones or dropping them, make a quick diagnosis, which will help narrow down the range of possible problems:
- Check the charge of the case and headphones: 🔌 Connect the case to the charging on 10-15 minutes, then try to remove the headphones. 🔦 Light a flashlight in the case - if the indicator on the right earphone does not burn, the problem is in the contacts or battery.
- Connection test: 📱 Remove headphones from the list of Bluetooth devices on your phone. 🔄 Turn off both headphones (press the button for 10 seconds), then turn on only the right one. 🔍 If it doesn’t appear in Bluetooth search, the problem is in the communication module.
Sound check
- 🎵 Connect the right earphone separately (if possible) and start the music.
- 🔊 If there is a sound, but quiet or distorted, the speaker or mesh is to blame.
If after resetting the right earphone still does not connect, try to connect it separately:
- 📱 Remove the right earphone from the case and hold the button for 10 seconds until the indicator starts flashing red and white.
- 🔍 Find it in the list of Bluetooth devices (could be called "Mi True Wireless EBs") Basic_R").
- 🔗 Connect to it and check the sound.
💡
If your headphones don't sync after reset, try connecting them to another phone or tablet, and sometimes the problem is with your smartphone's Bluetooth module, not your headphones.
⚠️ Warning: Do not use metal objects (clips, needles) to reset - this can damage the button. Press strictly with a finger with moderate effort.
Cleaning contacts and connectors: step-by-step instructions
If the right earphone doesn't charge in the case or connects intermittently, the problem may be oxidized contacts, which eventually accumulate dust, sweat or corrosion, which disrupts the connection.
You'll need to clean:
- 🧴 Cotton swabs (preferably with a sharp end).
- 💧 Alcohol (isopropyl or medical 90%).
- 🔍 Loop or flashlight for inspection.
