Connecting wireless headphones to Xiaomi Redmi via Bluetooth

Modern Xiaomi and Redmi smartphones are equipped with advanced wireless communication modules that make it easy to enjoy music or talk without unnecessary wires. However, users often have difficulties when pairing devices for the first time, when automatic search does not give the expected results. Understanding the basic principles of Bluetooth protocol on the MIUI or HyperOS platform will help avoid typical errors and save time.

In this article, we will take a closer look at the entire process, from activating visibility mode on the headset to fine-tuning audio codecs for maximum sound quality, and learn why the phone may not see new headphones and how to fix the situation if the connection was successful, but the sound is missing or not working correctly.

The process of synchronizing gadgets in the Xiaomi ecosystem usually takes no more than a minute, if all the conditions are met. We will consider both standard scenarios for Redmi AirDots models and the connection of third-party devices from Sony, JBL or Apple.

Preparation of headphones for pairing

The first and most critical step is to put the headset into detection mode. Many users make the mistake of just turning on the device, but for the first connection, this is not enough. Headphones must actively broadcast the signal so that the Xiaomi smartphone can “see” them in the list of available devices.

For most TWS (True Wireless Stereo) models, both earbuds must be removed from the case and the touch zones or physical buttons must be held for 3-5 seconds. The indicator must start flashing alternating colors, usually white and red, or quickly flashing blue, which means that the pairing mode is activated.

If you have a full-size headset, the algorithm may be different. Often you need to press the on button before the sound signal or voice message "Pairing" appears. Without this step, the Redmi smartphone will scan the airwaves, but will not find your device, as it is in sleep or standby mode.

• 🎧 Remove the headphones from the charging case or turn them on with the power button.
• 🔴 Hold the button or sensor until the indicator flashes quickly.
• 📶 Make sure the device is not automatically connected to another nearby gadget.
• 🔋 Check that the headphone battery is at least 20% for stable operation.

Activation of Bluetooth on the Xiaomi smartphone

Once the peripheral is ready, you need to configure the phone properly, and in the MIUI shell, the wireless modules are controlled in the top curtain of the notifications, but for the initial setup, you better use the full menu of parameters, which will avoid hidden restrictions or caching errors.

Open the Settings app and find the Bluetooth partition. Make sure the slider is activated. At this point, the phone will automatically search for devices. If you've previously connected many gadgets, it's recommended that you clear the list of old devices so that addressing conflicts don't arise.

💡

Turn on geolocation (GPS) before searching. In modern versions of Android and MIUI, it is a must for properly scanning Bluetooth devices, especially for low-power headphones.

It is important to note that in newer versions of the firmware, Xiaomi hides some system parameters. If standard search does not give results, try using advanced settings. Sometimes switching the visibility of the phone helps, although this is rarely required to connect headphones, since the initiative is usually shown by a smartphone.

The current Redmi supports standards 5.0, 5.2 and above, providing stable connection at a distance of up to 10-15 meters. Older headphone models will also work due to backward compatibility, but may have codec restrictions.

Process of connecting and pairing devices

When both devices are ready, the name of your headset should appear on the Xiaomi smartphone screen in the “Available Devices” section. Click on it to begin the mating procedure. The system can request code confirmation, although in 99% of cases for audio devices, pairing occurs automatically without input. PIN-code.

When you connect, you may see a pop-up asking permission to access your contacts and call log, and if you plan to use headphones for conversations, you must agree. For music, this permission is not critical, but it's convenient for managing calls.

Once you've successfully completed the process, you'll hear voice confirmation in your headphones or a distinctive beep. In MIUI, status will change to "Connected" with battery power if the headset supports this, and you can now run any media player.

If the connection is established but there is no sound, check the media settings. MIUI has a separate volume slider for Bluetooth devices that can be twisted to zero even if the overall volume of the system is maximum. Adjust the sound with buttons on the phone body after you connect.

Customization of sound and codecs in MIUI

For audiophiles and users who value quality, Xiaomi offers advanced settings in the developer menu.The standard SBC codec provides basic quality, but modern Redmi headphones and smartphones support more advanced compression formats such as AAC, aptX or even LDAC.

To access these settings, you need to activate the developer mode, you need to quickly click 7 times on the build number in the About Phone section, and after the message "You became a developer" appears, a new item will appear in the main settings menu.

In the developer section, look for the Bluetooth Audio Codec and choose the available one. Don't pick a codec that isn't supported by your headphones, in which case the connection may break or the sound will be distorted. Usually, the system itself offers the best option, but manual selection can improve the situation.

💡

Choosing the right codec can significantly improve sound quality and reduce latency in games, but requires support from both devices: both a smartphone and headphones.

Solving Visibility and Connection Problems

Despite the standardization of technology, Redmi users often face a situation where the phone does not see the headphones, which can be caused by a software glitch in the communication module or a crowded Bluetooth cache.

If the reboot didn’t work, reset your network settings. Note that this action will delete your stored Wi-Fi passwords and lists of all Bluetooth devices. After that, you’ll have to reset the pairing procedure. The path to reset: Settings → Connection and Sharing → Reset Wi-Fi, cellular networks and Bluetooth.

⚠️ Note: Before resetting your network settings, make sure to remember passwords from important Wi-Fi networks, as it will be impossible to recover them from your phone without root rights after resetting.

Another common cause is address conflict: If you've previously connected these headphones to another phone, they may try to connect to it automatically, ignoring a request from Xiaomi.

• 🔄 Reboot your smartphone and headphones completely.
• 🗑️ Remove the device from the list of “My devices” and find it again.
• 📡 Turn off Wi-Fi while pairing (sometimes frequencies conflict).
• 🔋 Charge headphones, low charge can block search mode.

Use of the Two Devices and Multipoint

Owners of the Xiaomi ecosystem often use multiple gadgets at once. Some advanced headphone models support Multipoint, which allows you to connect to two smartphones or a tablet and a phone at the same time. In MIUI, this feature works stably, but requires the right sequence of actions.

First, connect the headphones to the first device (like the Redmi Note), then turn off Bluetooth on it, but don't tear the pair. Put the headphones in pairing mode again and connect to a second device (like the Xiaomi Pad).

And you have to remember that when you play audio on one device, the other device will pause the media, and that's the normal behavior of the protocol, and to switch the sound source, you just have to start the track on the right device, and the headphones will automatically switch the stream.

⚠️ Warning: Simultaneous transmission of sound to two different Bluetooth devices (separation of audio stream) in standard firmware MIUI It's not supported. You can't stream music to two different pairs of headphones at once.
