I updated my CMF buds 2a a few days ago to firmware version 1.0.1.60. After the update I noticed than I can hear some sound from surrounding even when the ANC is on. It was not happening before the update. Before if I turned the ANC on it would instantly silence the surroundings. So I’m asking NOTHING to solve this issue. I’ve tried everything I could including resetting the earbuds, re-pairing with my mobile. Still nothing happend. Can anyone help me?
