How to sync Xiaomi Basic 2 headphones with any device: instruction 2026

Xiaomi Basic 2 wireless headphones (TWSEJ04LS) have become a popular choice thanks to a combination of affordable price, high-quality sound and ease of use. However, even with such simple gadgets, users often have questions: how to connect them to a smartphone, why one ear does not work, or how to reset if synchronization is lost.

Unlike flagship models like Xiaomi Buds 4 Pro, Basic 2 doesn’t support advanced features like LDAC or anti-noise, but their main advantage is versatility: they are compatible not only with Xiaomi smartphones, but also with devices on Android, iOS, Windows and even macOS. However, the connection process can vary depending on the operating system. Next, we will analyze all possible scenarios from basic synchronization to solving rare problems.

Preparation of headphones Xiaomi Basic 2 for the first connection

Before you start syncing, make sure the headphones are ready to go.

• 🔋 Charge the case: Connect the case to the power source (use the cable) USB-C The indicator on the case should be red during charging and white at full charge. The minimum charge level for a successful connection is 20%.
• 🎧 Remove the headphones: Take both earphones out of the case - they should automatically turn on (blitzes white indicator).If this does not happen, press and hold the touchpad on either of the headphones for 3 seconds.
• 📱 Activate Bluetooth: On the device you plan to connect to, turn on Bluetooth (in Android: Settings) → Connections → Bluetooth, in iOS: Settings → Bluetooth).

If the headphones have already connected to another device before, they can automatically try to connect to it, in which case you either need to reset the settings (more on this below) or temporarily turn off Bluetooth on the previous device.

⚠️ Warning: Do not remove headphones from the case more than 10 cm from the smartphone when you first connect. Otherwise, they may not fall within the range of Bluetooth Low Energy (BLE), and synchronization ends in error.

Sync with Android smartphone (including Xiaomi, Redmi, POCO)

Connecting to Android devices is the easiest scenario, especially if you have a Xiaomi smartphone, and it automatically recognizes the headphones and offers additional settings through the Mi Earphones app (if installed).

1. Open the settings → Bluetooth on your smartphone.
2. Make sure that the Xiaomi Basic 2 headphones are in pairing mode (white-red flashing light). If not, return them to the case, then pull them out again.
3. In the list of available devices, find the Mi Basic 2 or TWSEJ04LS and tap it.
4. Confirm the connection (if you request access to contacts or microphone, allow).

After successful connection, the headphone icon will appear in the status bar, and the Bluetooth settings will display the charge level of the case and headphones (if supported by your version of Android). Xiaomi devices with MIUI 12+ also activate the Double Touch function to control playback.

If the headphones are connected, but the sound is only in one ear, check:

• 🔊 Sound balance in accessibility settings (Settings) → Special opportunities → Sound settings).
• 🔄 Monosound: Turn off mono mode in Bluetooth settings (sometimes automatically enabled).
• 🔋 Headphone charge: if one headphone is discharged, it may not connect.

Connection to iPhone or iPad (iOS)

While the Xiaomi Basic 2 isn’t certified for iOS (unlike the AirPods), it works perfectly with iPhones and iPads.

1. Open Settings → Bluetooth on your Apple device.
2. Take the headphones out of the case and wait until they start flashing white-red (pairing mode).
3. In the list of devices, find the TWSEJ04LS or Mi Basic 2 and tap it.
4. Wait 10-15 seconds – the connection can take longer than on Android.

iOS will not display headphone charge levels, and dual-touch functionality may not work smoothly, and it’s also worth considering that Apple limits some features to uncertified devices:

• 🎵 Codecs: will only be used AAC (no support for aptX or LDAC).
• 🔊 Microphone: Could be worse than Android due to AirPods optimization.
• 🔄 Autoconnect: Sometimes you need to re-pair after rebooting your iPhone.

⚠️ Attention: On iOS 16+ When you first connect, you might see a warning that says, "This device is not certified for iPhone." It can be ignored, because it doesn't affect functionality.

💡

If the headphones don’t connect to your iPhone, try connecting them to your Android device first, then reset and try again on iOS. This helps wake up the Bluetooth module.

Sync with Windows 10/11 or macOS

Connecting to computers is a little more complicated than smartphones, but it's also doable, and the main difference is that there are no specialized control applications, so you have to do all the settings manually.

For Windows 10/11:

1. Press Win + I, select Devices → Bluetooth and other devices.
2. Click Add Add the device → Bluetooth.
3. Take the headphones out of the case and wait until they appear on the list as TWSEJ04LS.
4. Select them and wait for the connection to complete.

If the headphones are connected, but the sound is not:

• 🔊 Check if they are selected as the default playback device (control panel) → Sound).
• 🔄 Reboot the Bluetooth adapter (in Device Manager).

For macOS:

1. Open System settings → Bluetooth.
2. Make sure the headphones are in pairing mode (flashing white-red).
3. Find Mi Basic 2 in the list and click Connect.

On macOS, you may need to further configure the output device to System Settings → Sound. If the sound is interrupted, try turning off the Auto Switch to AirPods feature (if it is active).

Solving synchronization problems

If the Xiaomi Basic 2 headphones don’t connect or are unstable, the causes can range from software failures to hardware malfunctions. Here are the most common problems and solutions:

The headphones are not detected by the device

• 🔄 Reset settings: Put the headphones in the case, then press and hold the touchpad on both headphones for 10 seconds until the indicator starts flashing red and white.
• 📱 Reboot Bluetooth: Turn off and turn on Bluetooth again on the device you’re connecting to.
• 🔋 Check the charge: If the case charge level is below 10%, the headphones may not turn on.

The sound is interrupted or lagged

• 📶 Remove interference: Get away from Wi-Fi or microwave sources (they run at 2.4GHz, like Bluetooth).
• 🔄 Change the codec: In the Android Developer Settings (Settings) → The phone. → Assembly number (7 taps) → Developer settings → Bluetooth codec) select SBC instead AAC.
• 🎧 Check the density of fitting: If the headphones are sitting loose, a sensor in the ear may trigger that suspends playback.

One earpiece is down.

This is the most common problem, and the causes can be both software and hardware.

1. Return both headphones to the case, then pull them out again.
2. Check if the indicator is on a non-working headphone (if not, it is discharged or defective).
3. Reset the settings (see instructions above).
4. Connect the headphones to another device – if the problem remains, the earphone itself may be faulty.

⚠️ Warning: If one earphone still doesn't connect after reset, check if moisture has entered the charging socket inside the case. Xiaomi Basic 2 contacts are sensitive to oxidation - wipe them with alcohol and let them dry for 10 minutes.

Additional features and hidden capabilities

Despite the budget position, Xiaomi Basic 2 has a few hidden features that many users are unaware of:

• 🎵 Low Delay Mode: To reduce lag in games or videos, turn on Developer Mode → Minimize Bluetooth audio latency (on Android).
• 🔊 Equalizer setting: In the Mi Earphones app (available for Android), you can choose from three presets: Bass, Vocals or Balanced.
• 🔋 Fast charging: 10 minutes in a case gives up to 1.5 hours of playback (provided the case is charged).
• 🎧 Monosound for one ear: If you put one earpiece in the case, the second will continue to work independently.

It is also worth noting that Xiaomi Basic 2 supports dual connection (simultaneously to two devices), but only if both devices are running Android 10+ with Bluetooth 5.0 support.

1. Connect the headphones to the first device.
2. Activate Bluetooth on the second device and find Mi Basic 2 in the list.
3. Confirm Connection – Headphones will automatically switch between devices depending on the active sound source.

💡

For dual connectivity to work, both devices must support Bluetooth 5.0+. On the iPhone, this feature does not work.

Update of firmware (if available)

Unlike flagship models, Xiaomi Basic 2 rarely receive firmware updates. However, if your headphones are unstable, it is worth checking the relevance of the software.

1. Install the official Mi Earphones app from Google Play (no iOS app).
2. Connect the headphones to your smartphone and open the app.
3. If an update is available, a notice will appear "New firmware version is available."
4. Press Update and wait until the process is complete (3-5 minutes). Do not turn off Bluetooth or put your headphones in the case during the update!

The latest known firmware version for Xiaomi Basic 2 is V1.4.0.8 (released in 2023).

• 🎧 Automatically disabling one headphone.
• 🔊 Artifacts of sound at high volume.
• 🔋 Incorrect display of the charge level.

⚠️ Note: If during the update there is a failure (for example, the smartphone will run out), the headphones can stop turning on, in this case, only a complete reset (see section above) or contacting the service center will help.
