How to connect Sony wireless headphones to Xiaomi phone via Bluetooth

Xiaomi’s current smartphones, whether the flagship Mi series or the affordable Redmi and POCO lines, come with advanced wireless connectivity modules. However, users often face nuances when trying to pair them with high-quality acoustics from Japanese giant Sony. Simply turning on Bluetooth doesn’t always guarantee stable performance or activation of advanced audio codecs like LDAC, which are critical to unlocking the potential of sound.

The pairing process may vary depending on the version of the MIUI or HyperOS operating system, as well as the headset model. In this article, we will discuss in detail all the stages of configuration, from basic connection to fine-tuning the parameters for audiophiles, you will learn how to avoid typical errors and ensure maximum quality of audio transmission between devices.

Before you get to the technical steps, make sure your Sony headphones (whether popular WH-1000XM4, WF-1000XM5 or more affordable models) are fully charged. Low battery power often leads to intermittent signal or inability to enter pairing mode. Also check that your Xiaomi has Bluetooth module on and is visible to other devices.

Preparation of devices for the first pairing

The first step in the setup process is to put Sony headphones into detection mode. For most headband models, you need to press the power button for 7 seconds before the flashing blue indicator appears. For fully wireless models, the procedure may be different: you often need to remove headphones from the case and hold the touch panels or mechanical buttons for 5-10 seconds.

On the Xiaomi smartphone side, it's important not just to turn on Bluetooth, but also to check your visibility settings. Go to Settings → Bluetooth and make sure the switch is activated. If you've previously connected these headphones to another device that's nearby, they can automatically connect to it, ignoring the phone, in which case temporarily turn off Bluetooth on other gadgets.

It is worth noting that the MIUI-based Android operating system has its own power management features. Sometimes aggressive battery optimization can prevent the rapid detection of new devices, so it is recommended to close background applications that actively use the audio stream or network connection before starting the procedure.

⚠️ Note: If the headphone light flashes red and blue, but the phone can’t see them, try to move the headphones away from the Wi-Fi router. Working at 2.4 GHz can interfere with the initial handshake of devices.

To start the process successfully, make sure you follow the following steps:

• 🔋 Headphones charged at least 30% for stable operation of the communication module.
• 📱 Xiaomi phone has geolocation enabled (required for Bluetooth scanner in new versions of Android).
• 🎧 Headphones are in pairing mode (fast flashing of the indicator).
• 🚫 Distance between devices does not exceed 1 meter during the first connection.

Step-by-step connection instruction via Bluetooth menu

Once the hardware is ready, we'll go directly to pairing. Open the Settings menu on your Xiaomi smartphone and select the Bluetooth partition. The system will automatically start scanning available devices within range. The Available Devices list should show the name of your model, such as WH-1000XM4 or WF-C500.

Tap the name of the device in the list. On the screen of the smartphone you may see a request for confirmation of pairing or input PIN-In 99% of cases, Sony does not require code or is standard (0000 or 1234), but modern Android models conduct pairing without user participation using a secure key exchange protocol.

After the successful connection, the status will change to Connected. However, for full operation and access to the equalizer, noise reduction and codec settings, it is strongly recommended to install the Sony | Headphones Connect app from the Google Play store. Without it, many headphone functions will remain unavailable or will work in basic mode.

If the connection is successful, you will hear voice confirmation "Bluetooth connected" or a similar phrase in the headphones. In the notification curtain Xiaomi will appear the icon of the battery headphones, if the model supports the transmission of this setting. Now you can play the test track to make sure that there is sound.

Use the Sony Headphone Connect app on Xiaomi

The standard Bluetooth settings in MIUI are limited to basic features. To get the most out of your acoustics, Sony | Headphones Connect is a must-have tool. Once installed and first launched, the app will automatically find the connected headphones and prompt them to update their software. The firmware update is a critical step, as it often fixes compatibility errors with Qualcomm chipsets used in Xiaomi phones.

In the application interface, you can configure noise reduction modes (ANC), which is especially important for public transport, and there is also an Adaptive Sound Control feature that changes the sound settings depending on your activity (walking, waiting, running). For Xiaomi owners, it is important to check the settings in the System section inside the application and allow work in the background so that the smartphone does not “kill” the process of managing the headphones.

Special attention should be paid to the section "Sound quality." This is where the LDAC codec is activated, which allows you to transmit audio stream with a bitrate of up to 990 kbit / s, which is three times more than the standard SBC. Without activating this item in the Sony app and in the settings of the developer Xiaomi (more on what follows), you will not hear the difference between expensive headphones and a regular headset.

⚠️ Warning: After updating the headphone firmware through the app, you may need to re-pair.Don't be alarmed if the device disappears from the Bluetooth list - this is a normal procedure for flashing the communication module.

The main functions available through the application:

• 🎚️ Accurate adjustment of the equalizer of sound.
• 🔇 Noise reduction management and transparency.
• 🗣️ Adjusting the assistant’s voice and volume of conversation.
• 🔋 Monitoring the battery status of each headphone separately.

Configure high-resolution codecs and developer

For Xiaomi users who value high-quality audio, the important step is to activate high-resolution codecs. By default, Android can choose a conservative SBC or AAC codec for maximum compatibility. To force LDAC or aptX Adaptive (if supported by both devices), you need to use the developer menu.

To enter the developer menu on MIUI/HyperOS, go to Settings → About Phone and click on MIUI Version (or OS Version) 7 times. Once you have the message "You are a developer", go back to the main settings menu, select Additional → For Developers. Find the Bluetooth Audio Codec section and select Sony LDAC.

Consider that using high-resolution codecs increases the power consumption of both smartphones and headphones. In addition, in conditions of severe radio interference (metro, crowded spaces), the connection can become unstable. In such situations, the system will automatically switch to a lower bitrate or codec, but you can manually choose the priority of "Sound quality" or "Stable connection" in the LDAC settings inside the Sony application.

Solution: Connection and sound problems

Despite the standardization of technology, Xiaomi and Sony users sometimes face problems. One of the frequent complaints is low volume or no sound after connecting. This is often solved by resetting Bluetooth settings in the Settings menu → Bluetooth → (three dots in the corner) → Reset settings. Also helps clear the cache of the Bluetooth service through the application menu.

Another common problem is desynchronizing audio and video (video ahead of sound), which is typical of high-resolution codecs, and the solution is to shift the priority in the LDAC settings to "Stable Connection" or temporarily disable the high-resolution codec when watching video content. Also check if Mono-audio mode is enabled in special Android features.

If Sony headphones can’t see a Xiaomi phone at all, try a full headphone reset. For most models, this is done by pressing the power button and the NC/AMBIENT button simultaneously for 7-10 seconds (until the indicator flashes 4 times blue).

💡

If the sound is interrupted only in the pockets of jeans, it may be due to the screening of the signal by the fabric or body.Try to move the phone to another pocket or use the clip to wear a smartphone on the belt for inspection.

Optimization of work and maintenance tips

To extend battery life and connectivity stability on Xiaomi devices, it is important to properly configure power management. Go to Settings → Apps → All apps → Sony | Headphones Connect and select No Limits under Activity Control. This will prevent background processes that are responsible for automatically switching noise modes from being turned off.

Also worth mentioning is the Multipoint connection feature available on new Sony models, which allows you to communicate with two devices at the same time, such as a Xiaomi smartphone and a laptop. However, activating this feature can slightly reduce the quality of the codec or increase latency. If you do not use switching between devices constantly, it is better to keep only one connection active for maximum performance.

Regularly clean the case charging contacts (for TWS models) and dynamic headphone mesh. The accumulation of sulfur or dust can impair not only sound, but also the operation of touch sensors, which will lead to false control alarms. Use soft dry fabric or special cleaning products for electronics.

⚠️ Note: Do not use Sony headphones in extremely low temperatures (below). -10°C) in winter: Lithium-ion batteries lose capacity dramatically in the cold, which can cause the device to suddenly shut down in the middle of a conversation or track.

Following these simple rules will allow you to enjoy quality sound for years.

• 🧹 Regularly update the firmware of headphones through the application.
• 🔋 Do not allow full battery discharge to zero during long-term storage.
• 📶 Avoid using powerful electromagnetic radiation in areas.
• 📲 Keep an eye on system updates MIUI/HyperOS, which often contain patches for Bluetooth.

💡

The sound quality on the Xiaomi + Sony bundle depends on the activation of the LDAC codec and the correct resolution of the background work of the Sony Headphones Connect application.
