soundcore AeroFit 2 Pro features adaptive ANC adjustment by default, ensuring every user receives a personalized, optimal ANC experience. However, due to variations in leakage levels in different users, the adaptive adjustment process takes approximately 2 - 5 seconds. During the adjustment, you may notice the ANC effect gradually intensifying over time, which is normal. Please wait until the adjustment is complete to enjoy the best noise-cancelling experience.
