This issue is caused by wind noise changes when the car windows are open or by roaring sounds when the car drives over bumpy roads. These noises interfere with the ANC system. This problem will be resolved through an OTA update to the earbuds software. Please keep focus on the Xiaomi Earbuds APP update notifications and update when available.
Note:
This issue can occur with high-depth noise cancellation earbuds, particularly when driving at high speeds. Some earbuds reduce the noise cancellation effect to deal with this, while others simply adjust the noise cancellation algorithm to balance the wind noise.
