💡

If the Mi Home app doesn’t show the firmware version, try reconnecting the headphones: remove them from the list of Bluetooth devices, reset (press both touchpads for 10 seconds) and reconnect.

Official update via Mi Home (recommended method)

The safest method is to use the Mi Home app, which is suitable for 90% of users and does not require technical skills.

Charge the case of headphones to 50% and above

Make sure your smartphone is connected to Wi-Fi (update weighs ~15-20MB)

Manual update via PC (for power users)

If the official method doesn’t work (e.g. due to regional restrictions), you can update the firmware manually through your computer, which requires more action, but gives you access to the latest versions of the software even before they are released to Mi Home.

You'll need:

If after the update, the headphones began to work worse (for example, wheezing in the sound or noise cancellation worsened), try to roll back to the previous version of the firmware.

1. Download the old version of the software (for example, 1.4.0.8).
2. Perform manual firmware via PC (instruction above).

How to check the success of the update

After the procedure is completed, it is important to make sure that the firmware is actually updated.

1. Open Mi Home and check the version of the software in the device information.
2. Listen to the test track (we recommend using audiocheck.net to check the frequencies).
3. Check the working hours: 🎵 Turn on the music at 50% volume and record the discharge time. 🔋 Compare with the stated characteristics (up to 5 hours on headphones and 24 hours with a case).
4. Test the stability of the connection: Step 10 meters away from the phone (with obstacles).

If you notice improvements after the update (for example, the headphones are less likely to turn off or the bass has become deeper), then the procedure was successful. If the problems remain, they may be related to hardware malfunctions - in this case, contact the Xiaomi service center.
