Using these balance lead extension cables is a breeze. Just connect the male connector at one end to your device that needs the connection, and plug the female connector into the corresponding part. It's very simple and can be done quickly. When using, make sure the connection is firm to avoid loose connections that could cause problems. As for maintenance, keep the cables in a dry and clean place. Don't bend them sharply or pull them too hard, as this can damage the internal wires. If you notice any signs of wear or damage, it's best to replace the cable to ensure safety and proper functioning.
