Xiaomi Air 2 wireless headphones (TWS Earbuds Basic 2 and AirDots 2) receive firmware updates to improve sound, connectivity stability and run time. However, the process of upgrading the firmware often raises questions: where to download official files, how to avoid a device "brick" and what to do if the update is suspended. In this article, current ways to update for 2026, including manual method through Mi Home and alternative tools for power users.
It is important to understand that the firmware for Air 2 is different from firmware for other Xiaomi models (for example, Air 2 Pro or Air 2S). Using incompatible files can lead to loss of functionality of the headphones. We will understand how to check the current version of the software, where to find official and custom firmware, and what to do if after the update the headphones stopped connecting or emit foreign sounds.
Why you need to update the firmware on Xiaomi Air 2
The manufacturer releases firmware updates for Xiaomi Air 2 with specific goals:
- 🎵 Improvement of sound: frequency response correction, reduction of distortion at high volumes, support for new codecs (for example, AAC or aptX for some regions).
- 🔋 Optimizing power consumption: increasing the operating time to 4-5 hours on a single charge (instead of 3-4 hours in older versions).
- 📶 Connection stability: Correction of communication interruption bugs at a distance of more than 10 meters or in the presence of interference from other devices.
- 🛠️ New features: add support for dual connectivity (to two devices at once) or control gestures (for example, triple tapping to call a voice assistant).
According to user tests, after updating from version 1.4.0.9 to 1.7.1.0, battery life increased by 15-20%, and the number of artifacts when listening to music in FLAC format decreased by 2 times. However, not all updates are equally useful: some users complain of deterioration of the microphone after upgrading to the latest versions.
⚠️ Note: If your headphones are stable and sound-friendly, firmware updates are not necessary.In some cases, newer versions of firmware may introduce incompatibility with older smartphones (for example, on Android 8 and below).
How to check the current version of the firmware

- Through the Mi Home app: Connect your headphones to your smartphone via Bluetooth. Open Mi Home → Go to the Profile section → My devices. Choose Xiaomi Air 2. → Settings (⚙️) → About the program: The firmware version bar will indicate the current number (e.g., 1.5.0.7).
If the firmware version is below 1.4.0.0, it is recommended to update - old firmware has critical bugs that automatically turn off one of the headphones during a conversation. Versions above 1.7.0.0 are considered stable, but may require resetting after installation.
