What to do if the headphones Xiaomi Redmi Airdots: the full guide

The problem with Xiaomi Redmi Airdots' sudden shutdown is familiar to many owners of these popular wireless headphones.One earphone stopped connecting to the phone? Both devices are constantly breaking the connection through 5-10 Or, after the firmware update, the gadget was no longer identified in the list of available devices? These symptoms can indicate both software failures and hardware malfunctions.

Unlike wired analogues, TWS-The True Wireless Stereo requires synchronization not only with the sound source, but also with each other, and you get a failure at any stage, and you get one Airdots running and the other is silent, or both devices are plugged in and out. In this article, we will analyze all possible causes of the problem and give unique solutions for each model of the series (including the Airdots 3 Pro and Airdots S), which you will not find in the standard instructions.

Basic checks before repairs

Before you disassemble your headphones or drop them to factory settings, make sure that the problem is not in the obvious trivia. According to service centers, 37% of complaints about β€œdefaulting Airdots” are resolved at this stage.

Start with a check:

  • πŸ”‹ Headphones and case charges: even if the indicator is green, try to hold the device on charge 10-15 Sometimes the contacts are oxidized, and the real charge is lower than the one displayed.
  • πŸ“± Device Compatibility: Redmi Airdots officially supports Bluetooth 5.0, but may conflict with Android 8.0 and lower phones due to outdated protocols.
  • 🎧 Physical injuries: Check the connectors in the case and on the headphones themselves. Black dots or green plaque on the contacts is a sign of oxidation.
  • πŸ”Š Sound source: try connecting to another phone/tablet. If the headphones are working, the problem is setting your main device.

Pay special attention to the indicators on the case:

  • 🟒 Green flashing - headphones charge.
  • πŸ”΄ Red constant – a discharge below 10%, urgent charging is required.
  • 🟑 Yellow flashing – synchronization error between headphones.
  • πŸ”΅ Blue flashing - pairing mode (pairing mode).

⚠️ Attention: If the indicator on the case does not respond to the press of the button at all, this is a sign of a malfunction of the power controller.

2. Resetting headphone settings to factory

The most effective way to get back to work is hard reset, which cleans all the pairings that are stored and returns the headphones to a boxy state.

1. Get both earphones out of the case

2. Make sure they're on (blinks red/blue)

3. Discharge to 0% and charge to 100%

4.Prepare a second phone for the test-->

For Redmi Airdots 1/2 (classical):

  1. Put both earbuds in the case.
  2. Close the lid and wait 5 seconds.
  3. Open the lid and hold the button on the case for 15 seconds until the indicator starts flashing red and white alternately.
  4. Get your headphones out – they should automatically enter pairing mode (blinking blue).

For Redmi Airdots 3/3 Pro/S:

  1. Get both earphones out of the case.
  2. Press and hold the touchpads on both headphones simultaneously for 10 seconds.
  3. The indicators should go out, then blink red and white.
  4. Place the headphones back in the case for 5 seconds, then pull out - they're ready for a new connection.

After discharge:

  1. Remove Redmi Airdots from the list of conjugate devices in your phone’s Bluetooth settings.
  2. Turn on new devices and select Mi True Wireless EB* Single (for left) and Mi True Wireless EB* Stereo (for the right).
  3. Confirm the pairing on both headphones.

πŸ’‘

If you don't recognize one headphone after reset, try connecting the right one first and the left one later, and in some firmware, they only sync in that sequence.

3.Chronicity problems between headphones

A typical situation is that the phone sees both Airdots, but only one is sounding, or they are constantly switched off, indicating a loss of communication between the master (right) and the slave (left).

  • πŸ”„ Firmware failure after incorrect update.
  • πŸ“Ά Interference from other Bluetooth devices (such as smartwatches or speakers).
  • πŸ”‹ Different charge levels – if one earphone is 20% discharged and the other is 80% discharged, they may not sync.
  • πŸ› οΈ Mechanical damage to the antenna in one of the headphones.

Decisions:

Method 1: Forced resynchronization

  1. Place both headphones in the case and close the lid.
  2. Open the lid and wait until the lights start flashing white.
  3. Take out only the right earphone and wait 10 seconds – it should flash blue (pairing mode).
  4. Return the right earphone to the case, take out the left and wait 10 seconds.
  5. Get both headphones out – they should sync automatically (indicators will light up constantly).

Method 2: Update the firmware through Mi Home

For Airdots 3 Pro and newer models:

  1. Install the Mi Home app (version no lower than 6.5.400).
  2. Put the headphones on the phone.
  3. Go to Profile. β†’ Headphones β†’ Firmware update.
  4. If you have a new version, follow the on-screen instructions.
ModelThe latest firmware versionFeatures of the update
Airdots 1/21.4.0.3Update via PC only (Xiaomi Bluetooth Tool is needed)
Airdots 32.7.1.0Supports OTA-Update to Mi Home
Airdots 3 Pro3.1.5.8Requires Wi-Fi connection to download files
Airdots S1.0.12.4Update is possible only when the case is charged >50%

⚠️ Warning: Do not interrupt the firmware update process! If the headphone indicator flashes red and green at the same time, this means a critical error).

Hardware malfunctions and their diagnosis

If the software methods didn't work, the problem could be physical damage.

Signs of hardware problems:

  • πŸ”Š There is no sound in one headphone, but the indicator is on and the connection is there.
  • πŸ”‹ The earphone is discharged 10-15 minutes (battery malfunction).
  • πŸ“Ά Constant interference even within a meter of the phone (damage to the antenna).
  • πŸ› οΈ Buttons/sensors do not respond to pressing.

The most vulnerable elements of Redmi Airdots:

  1. Charging contacts -- oxidize because of sweat or moisture, and clean them with a cotton swab soaked in alcohol.
  2. The Bluetooth antenna is a thin conductor inside the body that can move away when it falls.
  3. The battery is through 1.5-2 The new headphone is only running when the charging cable is connected.
  4. Speaker – if the sound is distorted or absent, but the headphone is connected, the speaker or audio track is to blame.
How to check the speaker without disassembly
Connect the headphone to the phone and call another number. If you hear noise/squeak in the speaker during the call, but the music is not playing, the problem is in the audio codec (requires soldering).

For diagnostics, use test commands (working for Airdots 3 Pro):

Turn on the debugging mode in Mi Home:


adb shell am start -a android.settings.BLUETOOTH_SETTINGS




Signal level check:



adb shell dumpsys bluetooth_manager

What you can fix yourself:

  • πŸ”§ Cleaning contacts – use an eraser or alcohol.
  • πŸ”‹ Battery Replacement – Suitable Batteries: 3.7V 40mAh (for Airdots 1/2) or 3.7V 55mAh (for Airdots 3).
  • πŸ“Ά Antenna soldering – requires a soldering station and skills to work with SMD-component.
