4. Care and Maintenance

Proper care and maintenance will extend the lifespan and preserve the performance of your Superlux HD 660PRO headphones.

• Cleaning Ear Pads: The velvet ear pads can accumulate dust and oils. Gently wipe them with a soft, dry, lint-free cloth. For deeper cleaning, lightly dampen the cloth with a small amount of mild soap and water, then wipe and allow to air dry completely before use. Avoid excessive moisture.
• Cleaning Headband: The leather headband can be wiped with a soft, slightly damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Cable Care: Avoid sharp bends, kinks, or excessive pulling on the cable. Store the cable neatly to prevent tangling. The cable is durable but not designed to be detachable from the headphones themselves.
• Storage: When not in use, store your headphones in the included storage pouch to protect them from dust and scratches. Avoid storing them in extreme temperatures or high humidity.
• Avoid Drops: While built from rugged materials, dropping the headphones can damage internal components or the housing. Handle with care.
