Care and Maintenance
Cleaning
Gently wipe the earcups and headband with a soft, dry, lint-free cloth. Do not use liquid cleaners or solvents. Avoid getting moisture into the headphone openings.
Storage
When not in use, store your headphones in a cool, dry place. Avoid extreme temperatures and direct sunlight. Do not store heavy objects on top of the headphones.
Cable Care
To prevent damage, avoid sharply bending or twisting the audio cable. Always grasp the plug, not the cable, when disconnecting.
