Connecting Xiaomi wireless headphones to Samsung Galaxy A51: full instructions with tips

Xiaomi wireless headphones are a popular accessory among Android users, but connecting them to smartphones from other brands, such as the Samsung Galaxy A51, sometimes raises questions. Although both devices are Bluetooth-based, the nuances of pairing protocols and software features can be difficult. In this article, we will discuss not only the standard connection procedure, but also the typical errors, how to fix them, and give recommendations for optimizing sound for a better user experience.

It is important to understand that the Galaxy A51 supports modern versions of Bluetooth 5.0, which should theoretically provide stable connection with most Xiaomi headphone models (including Redmi AirDots, Mi True Wireless Earbuds and others). However, in practice, users face problems due to conflicts of A2DP profiles or, codec incompatibility (SBC, AAC, ), and the features of energy-saving modes of both devices.

1. Preparation of devices for coupling

Before you start connecting, make sure both devices are ready to interact. Let’s start with the Samsung Galaxy A51:

• 📱 Update the firmware: Go to Settings → Update the software and install the latest updates. This will eliminate possible bugs in the Bluetooth module.
• 🔋 Turn off the power saving mode: In Settings → Caring for the device → Battery → Power Saving Mode Turn Off This Option as It May Limit Bluetooth.
• 🎧 Reset network settings (if necessary): If you have previously had problems connecting other devices, reset to Settings → General settings → Reset → Reset the network settings.

Now prepare the headphones Xiaomi:

• 🔄 Reset the headphones to factory settings: For most models, this is done by holding the button on the case of the charging case for 10-15 seconds (until the indicator flashes in red/white).
• 🔋 Charge headphones and case: The charge level should be at least 30%, otherwise the pairing process may be interrupted.
• 📦 Check if your model supports Xiaomi protocol or higher (this is a requirement for Galaxy) A51).

3. Solving typical connection problems

If Xiaomi’s headphones don’t connect to the Galaxy A51, the reasons can range from software failures to hardware limitations.

If neither of these methods worked, try an alternative method of connecting via the Mi Home app or Xiaomi Wear (if it supports your headphone model).These apps sometimes let you bypass the limitations of a standard Android Bluetooth stack.

⚠️ Note: Some Samsung firmware (especially custom ones) may have Hands-Free Profile support turned off, resulting in no microphone in the headphones, in which case only flashing the phone or using headphones in mode will help. A2DP (sound-only).

4. Sound optimization and Bluetooth settings

For models with touch-enabled controls (such as Redmi AirDots 3 Pro), check the gesture assignment in the official Xiaomi Wear app. On Samsung, some features (such as calling a voice assistant) may not work properly due to the limitations of One UI.

6. Alternative ways of connecting

If standard Bluetooth pairing doesn’t work, consider alternative methods:

• 📱 Xiaomi Wear app: Install it from Google Play and follow the instructions for connecting the headphones.The app can offer a headphone firmware update that will solve compatibility issues.
• 🔌 Adapter usage: For older Xiaomi models (such as Mi Bluetooth Audio Receiver) you can connect via 3.5mm audio output on the Galaxy A51 (You'll need an adapter USB-C → 3.5 mm).
• 💻 PC Connection: In rare cases, pairing headphones with a computer and then “transmitting” them to the phone via Bluetooth Hand-over (available on some firmware) helps).

For dual-connection models (such as the Mi Earbuds 3 Pro), you can connect them to the Galaxy A51 and another device (such as a laptop).

1. Connect the headphones to the first device.
2. Activate the pairing mode on the headphones (hold the touch panel for 2 seconds).
3. Connect the second device via Bluetooth.

⚠️ Note: When dually connected to Samsung and an iOS device (such as an iPhone), profile conflicts may occur.

7. Update to Xiaomi headphone firmware

Outdated headphone firmware may be causing an unstable connection to the Galaxy A51.

1. Install the official Xiaomi Wear or Mi Home app from Google Play.
2. Connect the headphones to the phone via Bluetooth.
3. Open the app and go to the headphone management section.
4. If an update is available, follow the instructions on the screen. Do not interrupt the process, as this may cause the headphones to crash.

For some models (e.g. Redmi AirDots 2), the firmware update requires you to connect to Mi Account. If you don’t have a Xiaomi account, create it in advance. The update process takes 5-10 minutes, after which the headphones will automatically restart.

💡

Updating the firmware headphones can solve connectivity issues, improve sound quality, and add new features (like AAC codec support for Samsung).
