ANC issues during sudden outburst of any noise.

Hi there. I just got the Earfun Air Pro 4+. The sound quality is good but I am having some issues with the ANC. While it's great against wind, whenever a sudden outburst of sound happens (like a bus honking once or a group of people shouting in celebration within an area), the ANC stops for like 2-5s and starts working again. This wasn't the case with my previous earbuds from other brand. I hope Earfun fixes it via a firmware update.
