Why Xiaomi Headphones Don’t Connect to Each Other: A Complete Diagnostics and Repair Guide

Have you pulled Xiaomi headphones out of your case, but they stubbornly refuse to connect to each other? One earphone is working and the other is silent or flashing red? This problem is familiar to many owners of the brand's wireless headphones - from the budget Redmi AirDots to the flagship Xiaomi FlipBuds Pro. In 80% of cases, the malfunction is not due to a breakdown, but to software failures or the wrong sequence of actions.

In this article, we’ll look at all the possible reasons Xiaomi headphones don’t sync with each other, from the banal (discharged case) to the complex (damage to the Bluetooth module), you’ll learn how to reset the headphones to the factory without losing functionality, what manipulations with the smartphone will help restore communication, and when to contact the service center, and also – why the problem often occurs after updating the firmware and how to avoid it.

1. The main reasons why Xiaomi headphones do not connect to each other

Before you rush to refashion the device or carry it for repair, check the most common causes of malfunction. In most cases, the problem is solved in 5 minutes without special skills.

• 🔋 A dead battery case or headphones, and even if the light is green, the voltage could drop below the critical level for synchronization.
• 📱 Bluetooth conflict on a smartphone, especially for devices on a smartphone MIUI older than the 12th version, where the pairing settings are often confused.
• 🔄 Failure of the firmware of the headphones. Occurs after an interrupted update or improper disconnection from power.
• 🎧 Mechanical damage to the contacts: Oxidation or contamination of the connectors in the case or on the headphones themselves.
• 🔗 The headphones are tied to another device, and if they've previously connected to a tablet or laptop, you may need to manually reset.

According to statistics of service centers, in 60% of cases, a discharged case is to blame - users forget that it not only stores headphones, but also charges them. If the indicator on the case flashes red or does not burn at all, first connect it to charging for 15-20 minutes, and then try to synchronize the headphones again.

2. Step-by-step instructions: how to reset Xiaomi headphones to factory settings

If the headphones don't connect to each other even after charging, the first thing you do is perform a hard reset, which removes all the stored pairing settings and returns the device to the "out of the box" state. The instructions are suitable for most Xiaomi models, including the Redmi AirDots 2/3, Mi True Wireless Earphones 2 and FlipBuds Pro.

Put both headphones in the case and close the cover | Hold the button on the case (or touchpad on the headphones) for 10-15 seconds | Wait for the white / red indicator to flash 3 times | Get the headphones out of the case - they must automatically turn on the pairing mode-->

For touch-controlled models (such as the Xiaomi Buds 3 Pro), the algorithm is slightly different:

1. Get the headphones out of the case.
2. Touch and hold both touch panels simultaneously for 10 seconds.
3. The indicators on the headphones will start flashing red and white – this is a signal of a successful reset.
4. Put the headphones back in the case, close the lid and wait 30 seconds.

After reset, the headphones should automatically sync with each other and go to search mode (Mi True Wireless or a similar name will appear in the list of Bluetooth devices).

⚠️ Warning: Don't interrupt the reset process even if the indicators have stopped flashing.FlipBuds Pro models may need up to 20 seconds of button holding.

3. Bluetooth problems on a smartphone: how to fix

Sometimes the problem isn't with the headphones, but with the Bluetooth settings on the phone, especially for Xiaomi smartphones, where the branded MIUI shell can block the connection of "non-usable" devices.

• 📵 Turn off Bluetooth and turn it back on. It's trivial, but it works 30 percent of the time.
• 🗑️ Remove the headphones from the list of associated devices. Go to Settings → Bluetooth, find your headphones, click on the gear and select "Forget the device".
• 🔄 Reset the network settings. → System system → Resetting settings → Resetting Wi-Fi, Mobile Network and Bluetooth.
• 📱 Update the firmware of your smartphone. MIUI (below 12.5) there are bugs with wireless headphones.

If you’re using an iPhone or a smartphone from another brand, check to see if Low Power is on, which limits Bluetooth, and try connecting your headphones to another device (tablet, laptop) to confirm that the phone is the problem.

💡

Before connecting your headphones to your new device, turn off Bluetooth on all other gadgets nearby. Sometimes the headphones try to automatically connect to the last device used, which blocks synchronization.

4. Hardware malfunctions: when without repairs can not do

If all software methods have been tried, but the headphones still don't connect to each other, the reason may be a hardware breakdown.

The most common hardware problem is the oxidation of contacts in the case or on headphones.

1. Take out your headphones and inspect metal contacts (usually gold) for green plaque or dark spots.
2. Take a cotton swab dipped in isopropyl alcohol (at least 70%) and gently wipe the contacts.
3. Let it dry for 10-15 minutes, then try to reconnect the headphones.

⚠️ Warning: Do not use acetone, vodka or other aggressive liquids to clean, as they can damage plastic. Also avoid mechanical stress (such as needles) so as not to scratch the contacts.

5. Features of different models: Redmi AirDots vs FlipBuds Pro

Synchronization and reset algorithms may vary depending on the headphone model. Let's look at the key features of the most popular lines:

Redmi AirDots (1/2/3 generation):

• 🔹 To reset, hold the button on the case (not on headphones!).
• 🔹 After reset, the indicator flashes red and white alternately.
• 🔹 Frequent problem: one earphone discharges faster than another due to uneven charging in the case.

Xiaomi FlipBuds Pro:

Xiaomi Buds 3/4 Pro:

• 🔹 Have automatic reconnection, but sometimes "forget" the second headphone after the update.
• 🔹 For diagnosis, use the official Xiaomi Earbuds app (shows the status of each headphone separately).
• 🔹 Supporting. LC3-Codecs that may not work properly with older smartphones.

6. Frequent User Errors and How to Avoid Them

Many of the problems with Xiaomi headphones are caused by the wrong actions of users, and here are the most common mistakes and ways to prevent them:

• 🚫 Ignoring charging instructions. The case needs to be charged at least 1 time every 2 weeks, even if you don't use headphones. The battery runs out over time, and this can block synchronization.
• 🚫 Interrupt the upgrade process. If the headphones are updated through the app, do not remove them from the case and do not turn off Bluetooth until the process is complete.
• 🚫 Use of non-original chargers, cheap cables may not provide enough current, which causes the case to not fully charge.
• 🚫 Storing the headphones outside the case, which causes the batteries to drain and synchronization to fail.

Another common mistake is trying to connect your headphones to multiple devices at once, for example, if you've been listening to music on your laptop and then trying to switch to your smartphone, you might have a pairing conflict.

1. Turn off Bluetooth on the first device.
2. Remove the headphones from the list of conjugated devices on both gadgets.
3. Reset your headphones (as described in Section 2).
4. Connect them again to the desired device.

💡

If Xiaomi headphones don't connect to each other after updating the smartphone firmware, try rolling back the MIUI version or wait for a patch. Often Bluetooth bugs are fixed in the next builds.

7. When to contact the service center

If you’ve tried all the methods in this article, but the headphones still don’t sync, it’s time to contact the experts.

• 🔥 The case does not charge even after replacing the cable and power supply.
• 🔊 One of the headphones is completely silent (no sound, the indicator does not burn).
• 💧 Visible traces of corrosion or moisture inside the cover or on the headphone board.
