Maintenance
Proper care will extend the life of your ZizoAmp Pulse Z3 headphones.

Gently wipe the earbud bodies with a dry or slightly damp cloth. Do not use harsh chemicals or abrasive materials.
- Storage: When not in use, store your headphones in a clean, dry place, away from extreme temperatures and direct sunlight. Avoid tangling the cable by coiling it neatly.
- Water Resistance: The headphones are water-resistant, meaning they can withstand splashes and light rain. They are not designed for submersion in water. Avoid exposing them to excessive moisture or liquids.
- Cable Care: The cable is designed to be tangle-free. Avoid sharp bends or excessive pulling on the cable, especially near the jack and earbud connections, to prevent internal wire damage.
