Connecting wireless headphones to Xiaomi smartphone via Bluetooth: full instruction with problem solving

Wireless headphones have become an integral part of everyday life – they free you from wires, allow you to listen to music in the gym or on a walk, and also take calls without unnecessary manipulation. However, even owners of Xiaomi, Redmi or POCO smartphones sometimes have difficulties connecting a headset via Bluetooth. Problems can lie in incompatibility of protocols, outdated firmware, conflicts with other devices or banal user errors.

In this article, we will analyze not only the basic pairing algorithm, but also nuances that the manufacturer rarely mentions in official instructions. For example, why Mi True Wireless Earbuds can connect to only one earbud, how to reset the headset to the factory if it is “not visible” by the phone, and what code (AAC, aptX, LDAC) We'll focus on diagnosing common errors, from flashing indicators on headphones to malfunctions. MIUI.

1. Preparation of headphones and telephone for pairing

Before you start connecting, make sure both devices are ready to interact.

• 🔋 Charging: Most wireless headsets (including Xiaomi AirDots, Redmi Buds or Haylou) GT1) They require a minimum charge level to activate the pairing mode. If the indicator on the case flashes red, charge the device first.
• 📦 Case extraction: Many models (e.g. Mi True Wireless Earbuds 3) automatically turn on when removed from the case).
• 🔄 Reset: If the headset was previously connected to another device, you may need to reset. To do this, hold the button on the case (or the touchpad on the headphone) for 10-15 seconds until the indicator flashes red and white alternately.

Now check out the Xiaomi smartphone:

• 📱 Update: Go to Settings → The phone. → Update the system and install the latest patches. MIUI 13/14 Fixed errors with Bluetooth connection 5.2/5.3.
• 🔍 Turn off other devices: If your phone already has a speaker, fitness bracelet or car radio, they may cause interference. Turn them off in Settings → Bluetooth.
• 🛠️ Reset Bluetooth module: in Settings → Connections → Bluetooth → Select "Reset settings" to clear the cache of the coupled devices.

2. Step-by-step connection instruction

The pairing algorithm depends on the headphone model, but the overall scheme is the same for most devices. Consider the process with the example of Xiaomi Mi True Wireless Earbuds 2:

1. Activate Search Mode on Headphones: Remove both earbuds from the case. They will automatically turn on and go into pairing mode (indicators flash white). If this does not happen, press and hold the touchpad on both earbuds for 3 seconds.
2. Turn on Bluetooth on your phone: Open Settings → Connections → Bluetooth and move the slider to the “On” position. Alternatively, swipe down the screen and hold the Bluetooth icon in the notification panel.
3. Search and select your device: Find the name of your headphones in the list of available devices (e.g. Mi True Wireless Earbuds 2). Click on it and the pairing process begins. What to do if the headphones are not displayed in the list?Try to turn off/on Bluetooth on your phone, restart the headphones (put them in the case for 10 seconds and pull them out again) or reset the headset (see section 1).
4. Confirmation of connection: After successful pairing, the headphones will stop flashing and light up blue (or go out). the phone will display a notification "Connected to [headphone name]".

For dual-connection models (such as the Xiaomi FlipBuds Pro) after the first pairing, the headphones will automatically connect to the phone when removed from the case. If this does not happen, check the settings in the Mi Earphones app (available on Google Play).

3. Customize sound and codecs for optimal quality

Xiaomi uses SBC by default, which is the most versatile, but not the best, and if your headphones support AAC, aptX, or LDAC, you can manually turn them on:

1. Open Settings → Sound → Bluetooth sound quality.
2. Select the connected headphones from the list.
3. In the "Code" section, select the priority option: 🎵 AAC — Balanced quality for music (recommended for Apple Music and YouTube). 🎧 aptX/aptX HD — Low latency, ideal for games and video. 🎛️ LDAC — maximum quality (up to) 990 kbit/s), but may cause interference in weak signal conditions.

Important: The LDAC codec can automatically lower bitrates to 330 kbps with a weak Bluetooth signal. To turn this off, set the Quality Priority setting in the sound settings (not available on all models).

💡

If the sound is interrupted after changing the codec, go back to SBC or AAC, the problem may be an unstable Bluetooth connection.

4. Common mistakes and their solutions

Even after successful pairing, Xiaomi users face typical problems.

🔴 The headphones only connect to one ear.

Reason: the synchronization failure between the right and left earphones.

1. Put both headphones in the case for 10 seconds, then pull out.
2. Press and hold the touchpad on the right earpiece for 15 seconds until the indicator flashes red.
3. Reconnect via Settings → Bluetooth.

🔴 Phone can't see headphones

Algorithm of action:

1. Reboot your phone and headphones (put them in your case for 20 seconds).
2. Remove the headphones from the list of conjugated devices in Settings → Bluetooth, then reconnect.
3. Update the headphone firmware through the Mi Earphones app (if available).
4. Check compatibility: Some Xiaomi budget models (like the Redmi 9A) don’t support Bluetooth 5.0+.

💡

If the headphones don't connect anyway, try pairing them with another phone. If the problem persists, the headset is faulty (call the service).

5. Additional settings in MIUI to improve the work

MIUI offers hidden features that will help optimize the performance of wireless headphones.

• 🎚️ Equator: Go to Settings → Sound. → Equalizer and select preset (e.g. Bass or Jazz). Use manual mode for fine tuning.
