How to sync Xiaomi True Wireless headphones: full instruction with problem solving

Xiaomi True Wireless (TWS) wireless headphones have become an integral part of everyday life due to their convenience, compactness and high-quality sound. However, even such advanced devices sometimes have problems with synchronization — one earphone does not connect, only one sound comes in, or the gadget is not determined by the smartphone at all. If you encounter this situation, do not rush to bring the headphones into service: in 90% of cases, the problem can be solved by yourself in 5-10 minutes.

In this article, we will explore all possible ways to sync Xiaomi headphones, including models Redmi AirDots, Mi True Wireless Earphones, Buds and others. You will learn how to properly connect the device to Android and iOS, what to do when synchronization between the left and right earphones fails, and how to use proprietary applications for diagnosis.

Before you get to the instructions, check two key points: 1 Make sure the headphones are charged (the indicator on the case should burn white or green). 2 Disable other Bluetooth devices within a radius of 10 meters - they can cause interference.

If the problem persists, read on!

1. Standard connection Xiaomi TWS to the smartphone

Let's start with the basic method that works for most models: Redmi AirDots (2/3/Pro), Mi True Wireless Earphones 2/3, Xiaomi Buds 4 and others. The algorithm is the same for Android and iOS, but there are nuances.

Here's the step-by-step instruction:

1. Get the headphones out of the case. They should turn on automatically (white light flashes).
2. Activate the pairing mode: 🔄 For Redmi AirDots 2/3: Hold the button on the case. 3–5 seconds until the indicator flashes red and white. 🔄 For Mi True Wireless Earphones 2: touch the touchpad on both headphones at the same time on 2 seconds. 🔄 For Xiaomi Buds 4 Pro: Open the case cover – headphones will automatically go into search mode.

If the headphones are connected, but the sound is only in one, try rebooting them: put them back in the case, close the lid for 10 seconds, then pull out and reconnect.

2. synchronization of the left and right earphones between each other

One of the most common problems is when a smartphone sees only one headphone and the other doesn't connect or stay silent, because of a loss of synchronization between the left (L) and right (R) modules, and it solves the problem in several ways:

Method 1: Forced discharge

• 🔋 Put both headphones in the case and close the lid.
• 🔄 Hold the button on the case (or touchpad on headphones) for 15-20 seconds until the indicator starts flashing red and white alternately (this is a reset signal).
• 📱 Reconnect the headphones to the phone via Bluetooth.

Method 2: Manual synchronization (for touch-controlled models):

1. Get both earphones out of the case.
2. Touch the touchpad on the right earphone 3 times (for Mi True Wireless 2) or hold for 5 seconds (for Buds 4).
3. Repeat the same thing on your left earpiece.
4. Wait 10-15 seconds – the indicators should light up in synchronous white.

Method 3: Through the Mi Home app (Android only):

• 📱 Install the Mi Home app.
• 🔍 In the Devices section → Add the device select your headphone model.
• 🔄 Follow the instructions on the screen to re-synchronize.

4. Solving problems with connecting to different devices

Xiaomi TWS headphones can behave differently when connecting to Android, iOS, Windows or even Smart TV. Consider typical scenarios and their solutions.

Features of connecting to iOS:

• 🍎 On iPhone headphones Xiaomi can display as LE-... (Low energy. That's okay.
• 🔊 If the sound is only in one headphone, go to Settings → Bluetooth → (i) next to the headphones → Forget this device, then plug it back in.
• 📱 Buds 4 Pro models may need to turn off Automatic Sound Switching in AirPods settings.

💡

If the headphones are not connected to Windows, try removing all devices called LE-... in the Bluetooth Manager and repeat pairing.

5. Hardware problems and their elimination

If the software methods didn't work, the reason could be hardware malfunctions, and here are the most common cases and ways to diagnose them:

Problem 1: One earphone is not working.

• 🔌 Check the contacts in the case, they may have oxidized or contaminated.
• 🔋 Try charging the headphone separately: put it in the case and close the lid for 30 minutes.
• 🔊 If the headphone does not make any sounds (even system), the speaker or battery may have failed.

Problem 2: Headphones are not charged

• 🔌 Check the cable and power supply - try charging the case from another source.
• 🔋 If the indicator on the case does not burn, the charging controller may have broken.
• 🔧 Redmi AirDots 3 Pro models have a Quick Charging feature – make sure it’s enabled in the settings.

Issue 3: Persistent communication breakdowns

• 📶 Interference can create other Bluetooth devices (fitness bracelets, wireless mice.
• 🔄 Update the headphone firmware through Mi Home.
• 📱 On Android, turn on High Sound Quality Mode in Bluetooth Settings (can increase stability).

💡

If the headphones fall into water or are exposed to extreme humidity, immediately remove the batteries (if possible) and dry the device in rice or silica gel for at least 24 hours.

6. Hidden features and life hacks for Xiaomi TWS

Beyond the basic features, Xiaomi headphones have a few hidden features that few people know about, which can make it easier to use and even solve synchronization problems.

🎵 Game Mode (Low Delay)

💡

If the Xiaomi Buds 4 Pro headphones do not support LDAC (high resolution codec), update the firmware through Mi Home – in the latest versions this feature is added.

7. Frequent User Errors and How to Avoid Them

Many synchronization problems are caused by users' incorrect actions, and here are the most common errors and ways to prevent them:

❌ Error 1: Connecting headphones in a discharged state

⚠️ Attention! If the charge level of the case or headphones is below 10%, they may not sync or connect with interruptions.

❌ Mistake 2: Using a non-original charging cable

• 🔌 Cheap cables may not provide sufficient current, which is why the case is not fully charged.
• 🔋 Use a Quick Charge 3.0 Cable (for Buds 4 Pro models).

❌ Error 3: Connecting to multiple devices simultaneously

⚠️ Attention! If the headphones are connected to the smartphone and laptop at the same time, they can "forget" the main device.

❌ Error 4: Ignoring firmware updates

• 🔄 Updates often fix sync bugs. Check them in Mi Home every 1-2 months.
• 📱 On iOS updates may come less often – use Android device for update.

❌ Mistake 5: Storing headphones outside the case

• 📦 Long-term storage of headphones in the open air discharges the battery and knocks down the settings.
• 🔋 If you do not use headphones for more than a day, put them in a case - this prolongs the battery life.
