Xiaomi Air 2: Complete Guide to Using Wireless Headphones

Why Xiaomi Air 2 is worth the attention

Wireless headphones Xiaomi Air 2 (model) TWSEJ04LS) It has become one of the most popular TWS-Mi Ecosystem offers a balance of price, sound quality and functionality, which supports Bluetooth 5.0 technology, provides up to 14 hours of battery life with the case, and features touch controls that many users find intuitive. However, even such a simple device has nuances that are worth exploring to use it at 100%.

In this article, we'll look at not only the basics of connecting to your smartphone or controlling your music, but also the hidden possibilities: how to activate low latency for gaming, why your headphones might not sync with each other, and how to properly care for them to extend their lifespan. If you've just unpacked the Air 2 or have been using it for a long time, but want to learn something new, this guide is for you.

Separately, we will focus on the typical problems faced by owners: from the loss of sound in one earphone to the difficulties with updating the firmware. All solutions are tested in practice and adapted to the latest versions of the software (at the time of 2026).

Package and first steps: what goes into the box

Before you start setting up, make sure that the box with Xiaomi Air 2 contains all the necessary elements.

• 🎧 Two wireless headphones (left and right, marked L and R)
• 🔋 Charging case with charge level indicator
• 🔌 Cable USB Type-C for case charging
• 📄 Short instructions in several languages (including Russian)
• 🔄 Two spare pairs of embushures (sizes S and L, by default set M)

If there is something missing in your box, check it for damage — sometimes items like the mounts may fall out during transportation. Also, look for the serial number that is usually printed on the inside of the case lid, which will be useful for checking the originality of the device on the Xiaomi website.

The first thing to do after unpacking is to charge the case and headphones. Despite the fact that the manufacturer claims a small initial charge, it is better to connect the case to the power source for 1-2 hours.

• 🔴 Red lights -- charging's coming.
• 🟢 Green light - charging complete
• 🟡 Blinking yellow – an error (e.g. short circuit)

💡

If the indicator doesn’t burn at all, try using another cable or power supply. Sometimes the headphones don’t respond to charging due to a weak current (less than 1A).

Connecting Xiaomi Air 2 to a smartphone: step-by-step instructions

The process of pairing the Air 2 with the phone is as simple as possible, but there are a few things that can be difficult, and consider two scenarios: first connection and re-pairing (for example, after resetting).

First connection

1. Remove both headphones from the case - they will automatically turn on and go into pairing mode (the indicators on the headphones will flash white and red).

2.On your smartphone, activate Bluetooth and find Mi True Wireless Earphones 2 (or Redmi AirDots 2 – depending on the region) in the list of devices.

3. Click on the device name and confirm pairing. PIN-code, enter 0000.

Once successfully connected, the headphones synchronize with each other (left will become the lead, right - the follow). If synchronization does not occur, return the headphones to the case, wait 10 seconds and repeat the process.

Reconnect and reset settings

If the headphones have already been paired with another device or have problems connecting, reset:

Put both headphones in the case|Close the cover and wait 5 seconds.|Open the lid and hold the touchpad on both headphones for 15 seconds.|Indicators flash red - reset performed|Put your headphones back on.-->

On Android smartphones (especially Xiaomi/Redmi/POCO), it is recommended to use the Mi Earphones proprietary application for advanced settings.

• 🎛️ Customize control gestures
• 🔊 Select sound profiles (bass, vocals, balanced)
• 📊 View the level of charge of each headphone
• 🔄 Update the firmware (if updates are available)

Headphone management: gestures and voice assistant

Xiaomi Air 2 supports touch controls that can be customized to your needs, with the following gestures available by default (for both headphones):

* No noise reduction (ANC) feature is available in Xiaomi Air 2, but some firmwares can activate the "Transparency" mode to improve the perception of surrounding sounds.

To change the purpose of the gestures:

1. Open the Mi Earphones app.
2. Go to the Touch Controls section.
3. Select a headphone (Left or Right) and assign a new action for each gesture.

If the gestures don't work:

• 🧼 Wipe the touch panels with an alcohol wipe (fat or sweat can interfere with recognition).
• 🔋 Check the charge level – at a discharge below 10%, the sensor may not work properly.
• 🔄 Reboot the headphones (return to the case for 10 seconds).

Sound modes and low latency for games

One of the key features of the Xiaomi Air 2 is its support for Low Latency Mode, which reduces lag when watching videos or games.

1. Make sure the headphones are connected to the smartphone.
2. Open Mi Earphones and go to Sound Effects.
3. Activate the Low Latency Mode option.

In this mode, the sound delay is reduced to 80-100 ms (versus 150-200 ms in standard mode).

• 🎮 The mode only works with supported applications (for example, PUBG Mobile, Call of Duty, YouTube).
• 🔋 The autonomy of headphones is reduced by 10-15%.
• 📱 On iPhone, this mode may not work due to the limitations of iOS.

To improve the sound quality in the application, three pre-installed profiles are available:

• 🎵 Balanced – Balanced sound (by default).
• 🎶 Bass Boost - Higher Low Frequency.
• 🎤 Vocal Enhance – Emphasis on vocals (useful for podcasts).

💡

Low latency automatically turns off when talking on the phone or using a voice assistant.

Typical problems and their solutions

Even proven devices like the Xiaomi Air 2 can have problems, and let’s look at the most common ones and how to fix them.

The sound was missing in one earphone.

If one of the headphones does not play the sound:

1. Return both headphones to the case, close the lid for 10 seconds, then pull them out again.
2. Check if the speaker grille is contaminated (clean with a soft brush).
3. Reset the settings (see section above) and connect again.
4. If the problem persists, check the sound balance in your smartphone settings (Settings → Sound → Stereo Balance).

Headphones are discharged quickly

Standard operating time of Air 2:

• 🎧 Headphones: up to 4 hours on a single charge.
• 🔋 Case: Up to 14 hours with recharging.

If the autonomy is noticeably lower:

• 🔌 Use the original cable USB Type-C for case charging.
• 🌡️ Avoid overheating (do not leave headphones under direct sunlight).
• 🔇 Turn off low delay mode if you don’t need it.
• 📱 Update the firmware through Mi Earphones.

💡

To check the actual charge level of each headphone, use the Mi Earphones app or the Battery widget on iOS. The standard Bluetooth menu displays only the overall charge of the case.

Headphones are not synchronized

If the left and right headphones are connected separately or the sound is only in one:

1. Put both earphones back in the case.
2. Hold the button on the case (near the indicator) for 10 seconds until the indicator flashes red and white.
3. Take out the headphones and wait 20 seconds – they should sync automatically.

Firmware update: why and how

The manufacturer periodically releases firmware updates for Xiaomi Air 2, which fix bugs, improve connection stability and add new features (such as support for additional codecs).

1. Install the latest version of the Mi Earphones app from Google Play or the App Store.
2. Connect the headphones to your smartphone.
3. Open the app and go to the Firmware Update section.
4. If an update is available, press Update Now and wait for the process to be completed (the headphones will reboot).

Important points:

• 🔋 Make sure the charge level of the headphones and case exceeds 50%.
• 📶 Connect your smartphone to Wi-Fi – firmware files can weigh up to 10 MB.
• ⚠️ Do not interrupt the upgrade process – this can lead to loss of functionality of the headphones.

💡

Once the firmware update is done, all user settings (such as gesture assignments) are reset to factory settings, and they will have to be reconfigured.

Care and storage: how to extend the life of headphones

Xiaomi Air 2 has IPX4 protection, which means resistance to water splashes and sweat, but that doesn't mean it can be submerged in water or used in the rain.

• 🚿 After training, wipe your headphones and case with a dry soft cloth (do not use alcohol or abrasive materials).
• 🌡️ Do not leave your device in high temperature areas (such as on the dashboard of a car in summer).
• 🔋 Charge the case at least once a month, even if you do not use headphones (this prevents the battery from draining to a critical level).
• 🎧 Keep your headphones in a case – this protects them from dust and mechanical damage.

If the headphones have not been used for a long time and are discharged "to zero", it may be necessary to reanimate the battery:

1. Place the headphones in the case and connect it to the charger.
2. Leave at least 2-3 hours on charging, even if the indicator does not burn.
3. Try removing the headphones – if they don’t turn on, repeat the process.

💡

To clean the speaker grilles, use a toothpick with a cotton tip soaked in a weak soap solution. Do not use metal objects!
