How to pair headphones Xiaomi Airdots with each other: instruction + problem solving

Xiaomi Airdots wireless headphones (including Redmi Airdots, Mi True Wireless Earphones and their modifications) have become popular due to a combination of price, sound quality and convenience. However, many users face the problem when one of the headphones stops working or does not sync with the pair, most often after a reset, battery discharge or software failure. Unlike wired counterparts, wireless headphones require automatic synchronization between themselves before connecting to a smartphone or other device.

In this article, we will discuss why Xiaomi Airdots can “unconnect” and how to pair them together manually, and what to do if standard methods do not work. Also, you will find a table of model compatibility, FAQ for typical errors and tips for preventing problems. If you have already tried to reboot your headphones or reset the settings, but the result has not changed, do not rush to carry them to the service: in 90% of cases, the problem is solved by yourself in 5-10 minutes.

Why Xiaomi Airdots headphones don’t match each other

Before you start setting up, it's important to understand the cause of the malfunction, and here are the most common scenarios where Airdots lose communication:

• 🔋 Battery discharge up to 0% – if one of the headphones is completely discharged, and the second one is not, they can “forget” each other.
• 📱 Resetting settings on a smartphone – removing headphones from the list of connected devices sometimes leads to a break in their internal synchronization.
• 🔄 Update firmware – after the update via Mi Home or Xiaomi Wear headphones may require re-pairing.
• 🎧 Mechanical damage – falls or moisture often disrupt the Bluetooth module in one of the headphones.
• ⚡ Incorrect charging – using an unoriginal cable or adapter can cause a controller to malfunction.

Redmi Airdots S and Mi AirDots Pro are particularly vulnerable because their firmware is sensitive to sudden voltage changes. If the headphones stop syncing after connecting to charging, check the power supply first: it should give 5V/1A (for most Xiaomi models).

⚠️ Note: If one of the headphones emits intermittent audible signals (for example, beeps every 2 seconds), this indicates a hardware malfunction.

Preparation for pairing: what to do before the beginning

Before you start synchronizing, follow a few mandatory steps that will save time and increase your chances of success:

1. Charge the headphones. Make sure both earphones are at least 30 percent charged. To check, put them in the case and look at the indicators: if the white or green light is on, the charge is sufficient. Red or flashing orange means that you need to recharge.
2. Remove the headphones from the list of devices. On your smartphone, go to Settings → Bluetooth, find Mi Airdots, and click "Forget device" (or "Unplug"). This will force you to reset your current connection.
3. Check the case. Make sure the contacts inside the case are not oxidized or contaminated. Wipe them with a dry cotton swab if you notice any darkening.
4. Update your firmware. If you have a model that supports updates (such as Mi AirDots Pro), check the relevance of the software through the Xiaomi Wear app.

If one of the headphones doesn't respond to the buttons, try a forced reset: press the touchpad for 15-20 seconds until the indicator flashes red and white, which will return the headphone to the factory settings.

How to pair headphones Xiaomi Airdots with each other

There are three main ways to synchronize Airdots with each other: start with the simplest and move on to the next one if the previous one didn't work.

Method 1: Automatic synchronization through the case

This method works for most models (Redmi Airdots, Mi True Wireless Earphones 2, etc.) and does not require manual manipulation:

1. Put both headphones in the case and close the lid.
2. Wait 10-15 seconds, then open the case. The headphones should automatically turn on and sync (the indicators will flash alternately white).
3. Take the headphones out of the case - they must connect with each other (the beep will sound).
4. Connect them to your smartphone via Bluetooth.

If the lights flash red or only on one headphone, move on to the next method.

Method 2: Manual synchronization through buttons

This method is suitable for models with physical or touch buttons (Redmi Airdots S, Mi AirDots Pro):

1. Get both earphones out of the case.
2. Press and hold the button (touchbar) on the right earphone for 5 seconds until the indicator starts flashing white-red.
3. Repeat the action for the left earpiece.
4. Put both earbuds back in the case for 10 seconds, then pull them out. They should automatically mate (double beep).

If the headphones aren’t synced, try holding the buttons on both headphones simultaneously for 10 seconds.

Method 3: Resetting and re-pairing

The most radical, but effective method is a complete reset:

1. Put the headphones in the case and close the lid.
2. Press and hold the button on the case (if any) for 15 seconds. For models without a button on the case, use the touch panels on the headphones themselves (hold 20 seconds).
3. Once reset, the headphones will flash red, and you take them out of the case, and they'll automatically hide.
4. If this does not happen, repeat Method 2 (manual synchronization).

💡

If the headphones don't pair after reset, try connecting them to another device (tablet or second smartphone), sometimes the problem lies in the Bluetooth cache on the main gadget.

Table of compatibility of models and methods of interface

If your model is not listed in the table, try a universal algorithm: reset → automatic case synchronization → manual pairing. For models that support Xiaomi Wear (for example, Mi AirDots Pro 2), first update the firmware, then reset.

Frequent Mistakes and How to Avoid Them

Even after successful pairing, the headphones can "unconnect" again. Here are typical user errors and ways to prevent them:

• 🔌 Use of a non-original charger, power supply units with output current >1A You can damage the headphone controller. Always use a charger with settings. 5V/1A.
• 📴 Interrupt the pairing process. If you start syncing, do not put the headphones back in the case until the process is complete (sound signal).
• 🔊 Ignoring audio cues. Xiaomi Airdots emit different signals: one squeak to turn on, two squeaks to successfully pair, three squeaks to make a mistake.
• 📱 Connecting to multiple devices at once. Multithreaded mode (like a smartphone and a laptop) can disrupt synchronization.

⚠️ Note: If after pairing the sound is only in one headphone, check the audio balance in the settings of the smartphone (Settings) → Sound. → Stereo balance. Sometimes Bluetooth crashes down this parameter.

Software solutions: applications for diagnostics

If manual methods do not help, use the official utilities from Xiaomi:

• 📱 Xiaomi Wear – allows you to update the firmware, check battery power and reset the headphone settings. Suitable for Mi AirDots Pro, Mi True Wireless Earphones 2 and later.
• 🔧 Mi Home – in some regions supports Redmi Airdots diagnostics. To do this, add headphones as a new device and select "Update firmware".
• 🎛️ Bluetooth Auto Connect (third-party app) - helps to automatically connect headphones and fix pairing errors. Available on Google Play.

To use Xiaomi Wear:

1. Install the app from Google Play or the App Store.
2. Turn on Bluetooth on your smartphone and open Xiaomi Wear.
3. Click "Add device" and select your Airdots model.
4. Follow the instructions on the screen. If the app suggests updating the firmware, you can agree.

If the app doesn't see headphones, try:

• Reboot the smartphone.
• Disable VPN or firewall (they can block the connection).
• Use another smartphone for diagnosis.

💡

Updating your firmware through Xiaomi Wear solves the sync problem 70% of the time, and if the app doesn’t offer an update, you already have the latest version installed.

Hardware malfunctions: when you need help from the service

If none of these methods worked, it may be the hardware that's the problem, and here are some signs you should go to the service center.

• 🔴 One of the headphones does not turn on (does not respond to pressing, does not flash the indicator).
• 💧 Headphones were filled with liquid or subjected to severe humidity.
• 🔊 The sound is distorted or absent even after pairing (may indicate damage to the speaker).
• ⚡ Headphones are not charged (the indicator does not burn when placed in the case).

The average cost of repairing Xiaomi Airdots in service centers:

Before visiting the service, check if the warranty period has expired (usually 12 months from the date of purchase).
