Why Xiaomi AirDots Headphones Are Not Synced: A Complete Troubleshooting Guide

Xiaomi AirDots wireless headphones (including AirDots Basic, Pro, Pro 2, 3 and other models) SE) They've become some of the most popular accessories because of the combination of price and quality, but many users are faced with the problem of one or both earbuds not syncing with each other or with the phone. Unlike wired analogues, where it is enough to insert a plug, wireless communication depends on many factors: from the firmware version to the physical state of contacts in the case.

In this article, we will look at all the possible causes of Xiaomi AirDots’ non-synchronization, from trivial battery drain to hardware malfunctions. You will learn how to distinguish software failures from breakdowns, which reset button manipulations really work, and which myths (such as “flashing through the PC”) only exacerbate the problem.

1. Checking the basic conditions: what to do before resetting

Before you start a complex manipulation, make sure that the problem is not in trivial things. According to service centers, 37% of the calls with “default” AirDots are solved at this stage.

Start with a visual inspection:

• 🔋 Case and headphone charge: the indicator on the case should be white/green when connected to the charger. If the light bulb is red or not, it is a power problem. Try another cable and power supply (preferably original). 5V/1A).
• 📱 Device Compatibility: AirDots Require Bluetooth 4.2+ Android 5.0+/iOS 10+. On older smartphones (such as Redmi) 3S) There may be a lack of resources for a stable connection.
• 🎧 Physical contacts: Clean the metal jacks on the headphones and in the case with a cotton swab dipped in alcohol. Oxidation or dirt interrupts charging, causing one earphone to discharge faster and "fall off".

If the power and contacts are all right, go to check the software part:

1. Open the Settings. → Bluetooth on your phone and remove the Mi AirDots device from the list of conjugated devices.
2. Reboot the smartphone – it will reset the cache of the Bluetooth module.
3. Remove the headphones from the case and wait until they automatically go into pairing mode (blinking white LED). If this does not happen, read the section on hardware reset.

⚠️ Note: If the headphones have previously worked with another device (like a laptop), they may stick on it, in which case remove them from the list of Bluetooth devices on all gadgets they have mated with.

2. Software failures: firmware, cache and conflicts

A common cause of non-synchronization is the outdated firmware of headphones or phones. Xiaomi regularly releases updates for AirDots that fix connection errors. For example, version 1.7.4 for AirDots 3 Pro fixes a bug with a communication break when switching tracks.

How to check and update the firmware:

1. Install the official Mi Home app (for Android) or Xiaomi Wear (for iOS).
2. Connect your headphones to your phone and open the app. If you have an update, you'll see a notification.
3. Follow the instructions on the screen. Don't interrupt the process, it can lead to "bricking" of the headphones.

If the update doesn’t help or the app doesn’t see the headphones, try clearing the Bluetooth cache:

• On Android: Go to Settings → Annexes → Show all applications → Bluetooth, press Storage. → Clear the cache.
• On iOS: Remove the headphones from the list of devices, then reboot the iPhone (hold the power button) + volume up until the slider appears).

Another common problem is conflict with other Bluetooth devices, for example, if you have a 2.4GHz wireless keyboard nearby, it can cause interference.

• 📵 Disable all other Bluetooth gadgets.
• 📶 Switch router to 5 GHz channel (if supported).
• 🚪 Get away from sources of interference (microwaves, wireless speakers).

3. Hardware reset: when and how to do it correctly

If the headphones don't sync even after all the manipulations, it's time to do a hard reset. This procedure erases all the settings and returns the device to factory status. Importantly, the reset methods are different for different AirDots models!

Instructions for AirDots Basic/Pro/SE (1–2 generation):

1. Put both headphones in the case and close the lid.
2. Press and hold the button on the case for 15-20 seconds until the indicator flashes red and white.
3. Open the lid – the headphones should automatically go into pairing mode (blinking white light).

For AirDots. 3/3 Pro (2021–2026 years):

1. Take the headphones out of the case.
2. Press the touch panels on both headphones simultaneously for 10 seconds until the red LED flashes.
3. Put the headphones back in the case and close the lid for 5 seconds.

⚠️ Warning: After reset, the headphones may not immediately appear in the list of available devices. Wait 1-2 minutes or restart the phone's Bluetooth module (turn on / off aircraft mode).

If the reset didn’t help, check the synchronization between the headphones:

• Take both earphones out of the case.
• Touch the touch panel on the right earphone twice - the connection signal should sound.
• If the sound comes from only one headphone, the problem is in the master/subject device (read section 5).

4.Chronicity problems between headphones (one is not working)

One earbud is connected and the other is silent, and 23 percent of service calls are due to a breakdown in communication between master and slave devices.

How to determine which headphone is the main one:

• In AirDot models Basic/Pro main, always right.
• In AirDots. 3/SE Master role can be dynamically switched, but by default the main one is the one who first connected to the phone.

Communication recovery algorithm:

1. Put both headphones in the case and close the lid.
2. Wait until the charge indicator goes out (earphones completely turn off).
3. Remove only the main headphone (right) and connect it to the phone.
4. After successful connection, remove the second headphone – it should automatically synchronize (sound signal).

If the earphone is not connected:

• 🔄 Try changing roles: connect the left earphone first.
• 🔋 Check the charge of the led headphone - it could discharge in the case due to poor contact.
• 🛠️ If nothing helps, the problem may be in the Bluetooth antenna of the guided earphone (repair required).

💡

To check if the earpiece is alive, hold it to your ear when you ring, if you hear a slight noise or squeak, the device works, but it doesn't sync, if it's silent, the speaker or the board may break.

5. Hardware malfunctions: when it is time to go to the service

If all the software methods have been tried and the headphones are still out of sync, the cause may be physical failures.

The most vulnerable elements in Xiaomi AirDots:

• 🔋 Batteries: after 2-3 years, the capacity falls by 30-40%, which is why the headphones discharge unevenly and lose communication.
• 📡 Bluetooth module: In cheap models (for example, AirDots Basic) often fall off the antenna from vibration.
• 🔌 Case contacts: Oxidated by sweat or moisture, especially if you store headphones in the bathroom.

Cost of repairs in service centers (2026):

• Replacement of the battery in one headphone: 800-1 200 ₽.
• Case contacts repair: 500–900 ₽.
• Replacement of Bluetooth module: 1,500–2,500 ₽ (It is often cheaper to buy new headphones).

⚠️ Warning: If headphones fall into the water or have been hit hard, don't try to disassemble them yourself! AirDots uses adhesive joints, and if you disassemble them carelessly, you can damage the plumes of the speakers.

6. Alternative ways of connecting (if nothing helps)

If standard methods don’t work, try non-obvious solutions that sometimes save you in desperate situations.

Method 1: Connecting through third-party applications

Some AirDots models (especially AirDots 3 Pro) are better at interacting with alternative utilities:

• 📱 nRF Connect (Android) – allows you to manually initialize a connection.
• 🍎 Bluetooth Auto Connect (iOS) – automatically reconnects devices.

Instructions:

1. Install the app and turn on Bluetooth.
2. In the list of devices, find Mi AirDots_XXX (It can be displayed as LE-Audio).
3. Connect and wait for sync (can take up to 30 seconds).

Method 2: Forced assignment of roles master/slave

For AirDots. 3/SE:

1. Connect the right earphone to the phone.
2. Turn on the music and pause to stop the playback.
3. Twice tap the sensor on the left earphone – it should connect as a slave.

Method 3: Use of the second phone

Sometimes the headphones stick on one device to break the link.

1. Connect AirDots to another smartphone or tablet.
2. Play the audio for 1-2 minutes.
3. Turn it off and try connecting to the main phone.

💡

If the headphones connect to another device but not your phone, the problem is with your smartphone’s Bluetooth settings, not AirDots.

7 Prevention: How to avoid problems in the future

To Xiaomi AirDots last longer and do not lose communication, watch out for:

Charging and storage:

• 🔋 Do not keep your headphones discharged for more than 2 weeks – this reduces the battery life.
• 🌡️ Avoid overheating (do not leave the case in the sun or near the battery).
• 💧 If the headphones get wet, wipe them with a napkin and put them in rice for 12 hours (do not turn them on!).

Software updates:

• 📲 Check for updates to Mi Home regularly (every 2-3 months).
• 🔄 After updating the firmware of the phone (for example, before the MIUI 15) reconnect the headphones.

Physical condition:

• 🧴 Once a month, clean the contacts of the case and headphones with a cotton swab with isopropyl alcohol.
• 🎧 Do not drop the headphones - even from a height of 1 meter can come off the antenna.

💡

To check the actual charge level of the headphones (rather than the approximate one in the Mi Home), use the Battery Widget Reborn (Android) app or Bluetooth Battery Monitor (iOS).
