Could a failing Bose Music App Firmware Update cause the BOSE QUIETCOMFORT 45 to have symptom: Noise Cancelling Wind Noise?

The QC45's default 'Quiet' mode lacks the specific high-pass filtering required to distinguish between ambient noise and wind-induced pressure on the mic diaphragm. A firmware update (v3.0+) provides the 'Wind Block' custom mode, which re-tunes the DSP to suppress the specific frequency range associated with aerodynamic turbulence.

Could a failing Replacement Ear Cushions cause the BOSE QUIETCOMFORT 45 to have symptom: Noise Cancelling Wind Noise?

Degraded or improperly seated cushions compromise the acoustic seal of the earcup. This allows external air pressure to reach the internal feedback microphone, causing the ANC system to over-compensate and generate a rushing sound that mimics wind noise.

The 'wind noise' is a non-destructive byproduct of the headphones' Active Noise Cancellation (ANC) physics. External feed-forward microphones detect the pressure fluctuations of moving air as ambient noise; the system then generates an 'anti-noise' signal to cancel it. In high-flow environments, the amplitude of this turbulence exceeds the DSP's standard threshold, resulting in an audible rushing sound. This is an inherent limitation of the 'Quiet' and 'Aware' presets rather than a component failure.

NO REPAIR ACTION REQUIRED. PHYSICS CHECK CONFIRMED.
