How to synchronize wireless headphones Xiaomi Redmi Airdots Pro 2: full instruction

Xiaomi Redmi Airdots Pro 2 wireless headphones are popular because of their combination of price, sound quality and convenience. But even these proven gadgets sometimes have problems — for example, when one earphone stops connecting to another or works on its own. If your headphones are disconnected and do not sync with each other, do not rush to carry them into the service: in 90% of cases, the problem can be solved by yourself in a few minutes.

In this article, you will find step-by-step instructions on how to properly configure the Redmi Airdots Pro 2 among themselves, and we will also look at common user errors that lead to synchronization failures. We will look at both the standard way to connect and alternative methods in case the headphones “forgot” each other, plus a table decoding the LED indicators, which will help diagnose the problem by flashing light bulbs.

Warning: If the headphones are physically damaged (for example, after a fall or moisture), the software methods may not work, in which case repair or replacement will be required, but in most situations, the fault of the firmware or the wrong actions of the user is easily fixable.

Why Redmi Airdots Pro 2 headphones don’t sync with each other

Before you start connecting, it's important to understand the cause of the problem, and here are the most common scenarios where the headphones stop working in pairs:

• 🔋 The battery is discharged in one of the headphones (even if the second one is charged%.
• 📱 Wrong disconnection from the phone: if you take the headphones out of your ears and put them in the case at the same time, they can “forget” each other.
• 🔄 Failure of firmware after updating or abrupt power outage (for example, if the case is discharged during synchronization).
• 🎧 Mechanical damage to contacts in the case or on the headphones themselves (oxidation, pollution, bending of the "ears»).
• 📡 Interference with other Bluetooth devices: if there are active headphones, speakers or smartwatches nearby, they can interfere with the device.

Sometimes the problem is that the firmware is incompatible, for example, if one headphone is updated through the Mi Home app and the other one is not, they may lose communication, and it is also worth checking whether the phone is activated in Power Saving mode - it often blocks the background work of Bluetooth, which prevents stable synchronization.

⚠️ Note: If the headphones have never worked together (e.g., you bought them separately or after repairs), the standard instruction may not work.

Preparing for synchronization: what to do before the connection

Before you connect your headphones, follow the preparatory steps, which will increase the chances of successful synchronization and save time:

1. Charge the case and headphones to 100%. Even if the indicator shows a charge, connect the case to the network for 10-15 minutes - sometimes the power controller gives the wrong reading.
2. Clean the contacts on the headphones and in the case with a dry cotton swab. Oxidation or dirt can interfere with charging and synchronization.
3. Turn off Bluetooth on all devices nearby (phone, laptop, smartwatch), except the one with which you will configure the headphones.
4. Remove Redmi Airdots Pro 2 from the list of conjugate devices on your phone (if there are any). → Bluetooth → ⚙️ headphone-on → Forget the device.

If you have an Android smartphone, turn off the power saving mode and adaptive battery for the Mi Home app (if installed). On your iPhone, check that Settings → Bluetooth does not have active connections to other audio devices.

Also make sure you use the original cable to charge the case, because cheap ones may not provide enough current, which causes the headphones to not fully charge, which leads to synchronization failures.

The standard way to connect Redmi Airdots Pro 2 to each other

If the headphones used to work together but suddenly disconnected, try the standard sync method. It works 80% of the time and doesn't require resetting.

Here's the step-by-step instruction:

1. Place both earbuds in the case and close the lid. Wait 10 seconds, they should automatically turn off.
2. Open the case cover and wait until the headphone indicators start flashing white (this means they are turned on).
3. Take both earbuds out of the case and wait 15 to 20 seconds, and they should sync automatically, as signaled by the simultaneous flashing of white light.
4. Connect to the headphones from your phone. The list of Bluetooth devices should show the item Redmi Airdots Pro 2 (or Mi True Wireless Earphones 2).

If after 30 seconds the synchronization has not occurred (the indicators flash separately or one earphone does not respond), move to the next section with alternative methods.

💡

If one earphone does not blink after being removed from the case, try tapping your finger lightly on it - sometimes it helps to "wake up" the motion sensor.

Alternative synchronization methods if the standard one does not work

If the headphones are stubbornly reluctant to connect, try one of the alternatives, which is a little more complicated, but often helps in the "severe" cases.

Method 1: Forced resetting of one earpiece

This is a good way to do it if one earpiece is working and the other isn't (doesn't blink or flash red).

1. Put the working headphone in the case and close the lid.
2. Take out the non-working earphone and press the touch button on it for 15 seconds until the indicator starts flashing red and white alternately (this means that the reset is performed).
3. Put the dropped earpiece back in the case, then pull out both - they should sync automatically.

Method 2: Reset both headphones through the case

If both earphones are “glutching”, perform a full reset:

1. Put both headphones in the case and open the lid.
2. Press the button on the case (it is on the back side) for 20 seconds until the indicators on the headphones start flashing red.
3. Release the button, close the lid for 10 seconds, then open and pull out the headphones - they should sync.

Method 3: Connecting through the Mi Home app

If the headphones are synced but not connected to the phone, try using the official app:

1. Install Mi Home from Google Play or App Store.
2. Sign up or sign in to your Xiaomi account.
3. Click Add Device (+) → Headphones → Redmi Airdots Pro 2.
4. Follow the instructions on the screen (the application itself will suggest synchronizing the headphones).

⚠️ Warning: If the headphones stopped turning on after reset (don't blink, don't respond to buttons), this may indicate damage to the power controller.

Frequent User Mistakes and How to Avoid Them

Many of the problems with the Redmi Airdots Pro 2 are caused by the wrong connection, and here are the most common errors and how to avoid them:

• 🚫 You don't take your headphones out of the case at the same time. If you take one out and 10 seconds out of the other, they don't sync. Always take them out together!
• 🚫 Using the case while charging. Some users try to sync the headphones while the case is plugged in, which interferes with the process.
• 🚫 Press touch buttons during synchronization. Any touch can interrupt the process. Wait for the double blink, and then control the headphones.
• 🚫 Ignoring the indicators. If one earphone flashes red and you try to plug it in, it's useless. Solve the problem first (charge, reset).
• 🚫 Keeping headphones out of the case, if you leave them on a desk or in a bag, they will run out and "forget" each other. Always put them in the case after using them.

Another common mistake is using a non-original charging cable, because cheap cables may not provide stable voltage, which causes the case to not fully charge and the headphones to work incorrectly. Always use a cable from the kit or a certified USB-Type-C with Quick Charge support.

How to check if the headphones are successfully synchronized

It's not always obvious that the headphones are finally connected, but here are 3 ways to test a successful synchronization:

1. Indicators: After extraction from the case, both earbuds should flash white twice at the same time. If they blink separately, there is no synchronization.
2. Sound: When you connect to your phone, you're going to hear "Connected" on both headphones, and if you only have one, you're going to repeat the sync.
3. Stereo sound test: Play the song and check if it's going to both the left and right earphones, and if it's mono (only one), the headphones are not synchronized.

You can also go to Bluetooth Settings on your phone and see the status of the connection. If the headphones are synchronized, there will be one device displayed, Redmi Airdots Pro. 2. If two separate (Redmi Airdots Pro) 2_L and Redmi Airdots Pro 2_R) — So they work independently.

💡

If one earphone is turned off during listening after successful synchronization, the problem may be an unstable Bluetooth connection of the phone. Try connecting to another device (for example, a laptop) to check the performance of the headphones.

What to do if nothing helps: diagnosis and repair

If you've tried all the methods, but the headphones still don't sync, it might be a hardware problem.

• 🔧 Check the contacts in the case for oxidation or contamination. Carefully clean them with a wipe or an alcohol wipe.
• 🔋 Try charging the case with another cable (preferably original) and sometimes the problem is the damaged wire.
• 📱 Connect your headphones to another phone (like friends or family) if they work there, there's a problem with your smartphone.
• 🛠️ Contact the service center if the headphones are warranty.The failure of the Bluetooth controller or power can only be eliminated with soldering equipment.

If the headphones are no longer guaranteed, you can try self-repair:

• Disassemble the case and check the battery for swelling (if it is deformed - replace).
• Call the charging contacts with a multimeter - possibly a circuit break.
• Flash the headphones through the Mi Flash Tool (the instructions are on the profile forums, but it is risky!).

The cost of repair in the service is usually 500-1500 rubles, depending on the breakdown. If the headphones are older than 2 years, it is cheaper to buy new ones - the prices for Redmi Airdots Pro 2 start from 1,800 rubles.
