Copies of popular wireless headphones, such as AirPods i12, have gained immense popularity due to their affordable price and external similarity to the original. However, owners of smartphones based on Android often have difficulties during initial synchronization, since these devices are initially optimized for the ecosystem. iOS. The pairing process is not automatic in the form in which it is presented by Apple, and requires a number of specific actions to activate all functions.
Unlike the original models, where the chip W1 or H1 provides instant connection, budget analogues use a standard protocol Bluetooth. This means that you will have to manually manage the connection and setup through the system menu of your gadget. The correct sequence of actions guarantees stable audio operation and correct display of the battery level.
In this guide we will analyze in detail all the stages: from preparing the case to fine-tuning the touch controls. You'll learn how to avoid common mistakes that can cause audio to drop out or only work in one earbud. Follow the instructions carefully to get the most out of your music listening experience.
Preparing the i12 headphones for the first pairing
Before attempting to connect devices, you must ensure that the accessories are fully ready for use. Often connection problems arise due to a discharged battery or protective films on the contacts. Take the case and open the lid, checking the status indicator.
If the indicator is off or flashing red, put the case on wireless charging or connect the cable Lightning to a power source. Make sure both earbuds are firmly seated in their sockets and that the magnets are holding them securely. The contact pads must be clean, free of oxidation or dust.
An important step is to reset the previous settings if the headphones were previously used with another phone. This will prevent address conflicts MAC and protocol errors. Completely initialize the device before attempting a new connection.
⚠️ Attention: If you have previously connected these headphones to another smartphone, be sure to remove them from the list of paired devices on the old phone before setting up the new one.
To reset the settings, press the touch zones on both headphones at the same time and hold them for 10-15 seconds, until the indicators start flashing white. After that, put them back in the case and close the lid for 10 seconds. Now i12 ready to find a new owner.
☑️ Ready to connect
The process of connecting to an Android smartphone
Now we move on to the most important stage - establishing a connection with your phone. Enable Bluetooth in the settings of your Android smartphone. Do not try to search for the device while the headphones are inside the closed case.
Open the lid of the charging case, but do not remove the headphones themselves. At this point they should automatically go into pairing mode. The name should appear on the phone screen in the list of available devices i12 TWS or simply i12.
Click on the name of the device in the list. The system will ask you to confirm pairing. After a successful connection, you will hear a characteristic sound signal in the headphones, and the indicator on the case will stop flashing quickly and begin to glow steadily or go out.
- 📱 Open the Bluetooth settings on your phone and make sure that the switch is active.
- 🎧 Open the lid of the case with the headphones inside without removing them.
- 🔍 Find the name i12 in the "Available devices" list and click on it.
- ✅ Wait for the "Connected" message and check the sound.
Sometimes the phone sees only one earphone or the name is displayed incorrectly. In this case, close the lid, wait 5 seconds and repeat the procedure. If the problem persists, try restarting the smartphone itself.
If the phone does not see the headphones, try turning on and off the "Air Flight" mode on the smartphone - this will restart the wireless modules and clear the search cache.
Configuring the operation of sensors and controlling functions
After successful connection, it is worth understanding the controls, since the standard scheme can different from the usual. The sensors on i12 react to touches, but the sensitivity and purpose of actions may vary depending on the batch and firmware.
Usually a single touch is responsible for pausing or playing a track. Double-tapping is often used to switch songs, and triple-tapping is often used to call up the voice assistant or change the volume. However, in cheap copies the logic may be inverted.
For fine tuning, it is recommended to test each action. If the standard commands don't work, you may need a special application. In the Play Market there are utilities like AndroPods or Material Podsthat allow you to reassign button functions.
⚠️ Attention: The sensors on i12 replicas may be too sensitive. An accidental touch while adjusting the earphone in your ear can pause the music.
To change the volume directly from the headphones, try holding the touchpad for 2-3 seconds. In some firmware versions, this action increases or decreases the sound level, which is very convenient when running or in transport.
Secret double-tap function
In some firmware, double-tapping on the right earpiece activates Siri or Google Assistant, even if the phone is locked. This can drain the battery faster if it happens accidentally.
Battery charge display features and widgets
One of the main problems when connecting copies to Android is the incorrect display of the charge level. Unlike the iPhone, where the animation appears automatically, on Android you need to make an effort to customize the widget.
The standard Bluetooth menu often shows only the overall charge level or the charge of the case itself, ignoring individual headphones. To obtain detailed information, you need to install a third-party application from the store Google Play.
Popular apps, such as AssistantTrigger or PodsWidgetsemulate a pop-up window when opening the case. They read data through a protocol HID and output it in iOS style. This allows you to see the percentage of charge of the left and right headphones separately.
| Application | Functional | Requirements | Compatibility |
|---|---|---|---|
| Material Pods | Widget on the desktop, exact % | Android 8.0+ | High |
| AndroPods | Pop-up window, sensor settings | Android 7.0+ | Medium |
| PodsWidgets | Different widget styles, charge history | Android 9.0+ | High |
Please note that such applications work in background and may consume additional energy. If phone battery life is critical for you, use the standard Android battery widget by adding it to your home screen.
To accurately monitor the charge of each earphone, be sure to use third-party widgets, since the standard Android interface does not support the i12 battery detail protocol.
Problem solving: sound in only one earphone
The most common complaint from users is when music plays only in one ear, and the other is silent. This occurs due to desynchronization of the stereo channels between the left and right modules. They stop “communicating” with each other.
To fix this, you need to force the headphones into mono mode, and then combine them again into a stereo pair. Place both headphones in the case and make sure they are charging.
Take out both devices at the same time and quickly press the sensors 4-5 times in a row on each. The indicators should flash red and white, signaling a reset and search for a pair. Put them back in the case for 10 seconds.
- 🔄 Remove the i12 device from the list of paired ones in the Bluetooth settings.
- 🔌 Put the headphones in the case and close the lid.
- 🖐️ Press the sensors of both headphones 5 times (not taking them out).
- 📡 Perform the connection procedure again as for a new device.
If after these manipulations the problem is not solved, check the sound balance in the accessibility settings of your phone. Sometimes a failure occurs at the system level, and not at the headphones themselves.
⚠️ Attention: Do not try to disconnect the headphones one by one during use. Always take them out of the case at the same time or one at a time, but with a pause of 3 seconds so that they have time to synchronize.
Optimizing sound quality and codecs
The quality of music playback depends not only on the headphone drivers, but also on the codec settings in Android. By default, the system may use the old codec SBC, which gives average sound quality.
To improve the situation, you can activate more advanced codecs if your version of Android and headphone firmware support it. Go to Settings → For developers and find the section Bluetooth audio codec.
Try switching the value from SBC to AAC. This is the standard codec for Apple devices, and i12 copies often work best with it. The changes will take effect after reconnecting the headphones.
You can also change the bitrate and sampling frequency in the developer menu. Set to 48.0 kHz for clearer sound. However, remember that too high values can lead to audio delays in videos or games.
Settings → About phone → Build number (7 taps) → For developers → Bluetooth audio codec → AACExperiment with the equalizer settings in the music player. Budget i12 speakers often have low treble, so a little HF boost will make the sound more detailed.
Turn on the Absolute Volume feature in the developer menu to sync the volume of your phone and headphones. This will prevent a situation where the phone is at maximum, but the ears are quiet.
Frequently asked questions (FAQ)
Why do the i12 headphones not connect to the phone?
Most often the problem is that the headphones have not entered pairing mode. Make sure they are charged and perform a factory reset by pressing the sensors 5 times. Also check if they are connected to another device nearby.
Can one i12 earbud be used separately?
Yes, you can use the left or right earbud independently. Just take the one you need out of the case and leave the other one inside. To return to stereo mode, put both back in the case and close the lid.
How to check the authenticity or firmware version?
The i12 model does not have official authentication as it is a replica. The firmware version can only be found out through special engineering applications on Android, but for the average user this has no practical significance.
Why does the microphone work poorly during calls?
Microphones in budget copies are located inconveniently and are sensitive to wind. Try not to cover the microphone opening with your fingers and speak in quiet rooms. In noisy places, the quality of communication will be low due to the lack of active noise cancellation.
How long does it take to charge the case and headphones?
Usually, a full charge of the headphones themselves takes about 40-60 minutes. Charging the case from the mains takes approximately 1.5–2 hours. The operating time on a single charge is 3–4 hours of continuous listening.
