Why is the adaptive noise cancellation function of the Redmi Buds 6 Pro not working?

There are several potential reasons for this issue:
1. First, ensure that the earbuds are correctly worn. The adaptive noise cancellation function can not activate if the earbuds are not properly positioned in your ears;
2. Check the current noise cancellation settings in the Bluetooth settings interface or the Xiaomi Earbuds APP on your phone to confirm whether noise cancellation is turned on and if it is set to automatic;
3. The adaptive noise cancellation function is activated when there are significant changes in the surrounding environment noise. In quieter settings, the earbuds can reduce the noise cancellation intensity to enhance comfort.
