After Apple released the 4E71 AirPods Max embroidery update in May of this year, users began to complain about the deterioration of the active headphone noise function.
– reported one of Reddit's users to another user.
The owners of AirPods Max had previously encountered how the headphone battery had poorly held the charge, but the problem had been eliminated. The deterioration of the noise control function was a completely new problem. Journalist Umar Shakir reported that he had discovered that it had occurred after the automatic upgrade of the AirPods Max embroidery had taken place.
As noted by the 9to5Mac resource, there is currently no way to improve the ANC on AirPods Max. But there is good news. It has become known that Apple has been testing a new upgrade for AirPods Max for several months now. In particular, it is reported that earphones will receive new LC3 codes to improve audio calls. It is hoped that the ANC problem will also be corrected.
