How to clean

Short answer

Unplug any cables and remove the ear cushions. Clean them and the headphones with a damp, lint-free cloth. Avoid getting moisture in any openings.

Headphones come in close contact with your skin frequently and sometimes for long periods of time. This may over time cause build-up of dirt and grease that can affect performance and cause skin irritation. Clean your headphones regularly to keep them fresh and make them last longer.

Unplug any cables before cleaning the headphones.
Remove the ear cushions by turning them anticlockwise and clean them separately. To put back the ear cushions, place them on the earcups tilted at a slight angle, and turn them clockwise to lock them in place.
Gently clean the headphones, headband, ear cushions and cables with a lint-free cloth, slightly damp with either water, 70% isopropyl alcohol, or 75% ethyl alcohol. Avoid getting moisture in any openings or in the speaker mesh. Carefully clean those areas with a dry and soft brush, or a cotton swab.
Make sure everything is completely dry before charging the batteries, plugging in any cables, or using the headphones.
Do not use any sharp objects.
Do not use compressed air.
Do not use products containing bleach or hydrogen peroxide.
Do not submerge the headphones in any cleaning agents.
Do not rinse the headphones under running water.
