Clean the Microphone Ports on the Marshall Monitor II A.N.C.

Follow these steps to remove obstructions from the external microphone ports to restore proper ANC functionality:

1. Power off the headphones completely to prevent accidental input during cleaning.
2. Inspect the small microphone apertures located on the exterior of the affected earcup for visible lint, dust, or debris.
3. Using a clean, dry, and soft-bristled brush (such as a clean soft toothbrush or a fine-tip artist brush), gently sweep the microphone port to dislodge any trapped particles.
4. If moisture or oils are present, use a dry, lint-free microfiber cloth to gently wipe the area. Do not use compressed air, liquids, or sharp objects, as these can damage the internal microphone diaphragm.
5. Once the port is clear, power on the headphones and enable A.N.C. to verify that the wind-like noise has dissipated in a quiet environment.
