The process of activating the Xiaomi Air 2 SE wireless headphones (model BHR4272GL) is usually easy, since the device is designed with the expectation of instant start. However, new users often have questions about how to activate pairing mode for the first time or how to make the gadget work after a long idle. Understanding the logic of the case and the headphones themselves is key to successful operation.
Unlike wired acoustics, there is no physical power button on the case, as automatic activation occurs when removed from the charging case. It is important to distinguish between turning on the headphones themselves and turning on the search mode for Bluetooth devices, since these processes can occur automatically or require manual intervention depending on the history of the device. Below we will discuss in detail all the nuances of launch.
You don't need any sophisticated tools or special applications to get started, although using Xiaomi Earbuds (or Mi Buds M) greatly expands the functionality. Just remove the devices from the case and they have to go into active state, which is signaled by the lights, and if this does not happen, then you need to perform a number of additional diagnostic actions.
Primary activation and preparation for work
Immediately after being removed from the factory packaging, the Xiaomi Air 2 SE can be in deep energy-saving mode or completely discharged. The first step should always be to check the charge level. Even if the case indicator is lighted, it is recommended to charge the device for at least 15-20 minutes before the first attempt to turn on, in order to activate the chemical processes in lithium polymer batteries.
💡
Before first use, fully charge the case and headphones to calibrate the battery indicators and avoid false discharge readings.
The initial switching process is mechanical. When you open the case, the headphones are out of sleep, but the connection to the phone is not established until it's the first turn on. The internal logic of TWS (True Wireless Stereo) is that the right earpiece usually acts as the master, and the left one connects to it, creating a single stereo pair.
If you open the case and the lights don't light up, check the protective films on the charging contacts. New devices often have microscopic insulators that block the current supply. Make sure the magnets hold the headphones tightly in the sockets -- only when contact is made, automatic synchronization and charging occurs.
☑️ Pre-insertion check
Automatic on and on-line entry
The main use case involves the Xiaomi Air 2 SE turning on automatically when removed from the case. Once you pull out the headphones, they go into a standby mode. If the device was not previously associated with your smartphone, it automatically goes into Bluetooth visibility mode, waiting for an external gadget to search.
Importantly, the pairing mode may not be activated immediately if the headphones are removed at the same time, in some cases, you need to remove one headphone (usually the right one), wait for the signal, and then the second one, which provides the correct hierarchy of connection, where you first establish a link between the headphones themselves, and then with the phone.
⚠️ Warning: If the headphones are flashing white quickly and continuously, this means pairing mode. If they are flashing slowly or not at all, the device may already be connected to another gadget nearby.
To force the search mode to go, if the automatic one doesn't work, touch control is used, you need to put both headphones back into the case without closing the lid, and press the touch areas of both headphones simultaneously, holding your fingers for 5-7 seconds will cause the current connection to reset and trigger detection mode.
How does the connection priority work?
Connection with Android and iOS devices
The process of connecting to the smartphone depends on the operating system, although the basic Bluetooth protocol remains the same. For Android users, especially owners of Xiaomi, Redmi and Poco smartphones, the feature of quick pairing through the pop-up (Mi Pop-up) is available.
If the automatic window does not appear, you need to go to the system settings. The path usually looks like: Settings → Bluetooth → Device Search. The name Xiaomi Air 2 SE or Air2 SE should appear in the list of available devices.
For iOS (iPhone) owners, the procedure is standard for any Bluetooth headphones. Once you activate the pairing mode on your headphones, go to Settings → Bluetooth on your iPhone. Find the device in the Other Devices list and click on it. Note that some features, such as checking the charge of each headphone separately, may not be available without installing third-party apps from the App Store.
And you have to consider that when you first connect, the headphones can ask for permission to access contacts or call logs, and that's what you need to do to properly display the name of the caller, and if you don't, the headphones will work like a normal headset, but without displaying the name of the caller.
Use the Mi Buds M app to customize
While basic inclusion is possible without additional software, for full operation Xiaomi Air 2 SE is strongly recommended to install the application Mi Buds M (formerly known as Xiaomi Earbuds).This tool allows you not only to see the exact percentage of charge, but also to adjust the touch control, which by default may not be optimal for all users.
The app has a headphone search feature, which is extremely useful if you lost one at home, and you can also update your headphone firmware through the software, and manufacturers often release updates that improve the stability of the connection and the quality of the microphone noise reduction during conversations.
The application interface allows you to reassign actions when you touch double or triple. For example, you can set the left earphone to call the voice assistant and the right earphone to switch tracks. Without the application, these settings are often locked or have a standard, unalterable look.
💡
The Mi Buds M app is a must-have tool for firmware updates, which often solves problems with sound desynchronization and communication breaks.
Diagnosis: what to do if the headphones are not turned on
When Xiaomi Air 2 SE does not respond to the extraction from the case, it is rare, but requires a systematic approach to the solution. The first and most common cause is oxidation or contamination of contact areas, which can get earwax, dust or moisture, which creates an insulating layer.
To clean, use a cotton swab slightly soaked in alcohol or a special electronics cleaner. Gently wipe the contacts on the headphones themselves and inside the case. Allow the alcohol to evaporate completely before re-installing the headphones into the charging case.
If the cleaning didn't work, there may have been a software failure, and the headphones are stuck in deep sleep, in which case you need to perform a forced reset. Put the headphones in the case, open the lid and press the touch zones on both headphones simultaneously. Hold them for about 20-30 seconds until the indicators light up red and then start flashing white.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The indicators don't burn. | Case or headphones discharged | Put it on 30 minutes charge. |
| There's only one on fire. | Contact or dissynchronization is broken | Clean contacts, make a reset |
| Blinking red | Critically low charge | I need you to charge. |
| Not visible in Bluetooth. | The pairing mode is inactive. | Hold sensors 5-7 seconds |
⚠️ Warning: Do not use sharp metal objects (needles, scissors) to clean contacts inside the case.This can short-circuit and irreversible damage to the electronics of the charger.
Management and core teams after inclusion
Once successfully switched on and connected, the main interaction tool remains the touch panels located on the leg of each earpiece, which respond to light touches, but do not support volume control by compressing the leg, since the Air 2 SE uses capacitive rather than mechanical sensors.
The standard configuration includes playback/pause with double touch, activation of the voice assistant with triple, and acceptance/completion of a call with single touch during an incoming call.
For users who want to change standard behavior, once again, without the Mi Buds M app, the options are limited, but even in basic mode, the voice assistant (Google Assistant or Siri) allows voice playback and calls to be controlled, which makes up for the lack of physical buttons.
