Internal Feedback Microphone Array
The hissing is typically caused by a malfunctioning MEMS feedback microphone inside the earcup. These microphones monitor the sound reaching the ear to generate 'anti-noise'; if the microphone's signal-to-noise ratio degrades due to moisture or component failure, it generates a constant high-frequency hiss. Replacing the internal mic array or cleaning the acoustic port resolves the feedback loop error.
