Using the Ernie Ball Combo Cable is super easy. Just connect it between your instrument and your headphones or in - ear monitors. Whether you're on stage or at home, it'll work great. When using it, make sure the connections are secure to avoid any sound issues. As for maintenance, keep it away from sharp objects to prevent cuts. After use, coil it up gently as the housing is designed to be easy to coil. Don't tug on it too hard as this could damage the internal wiring. Store it in a dry place to keep it in good condition.
