Using this Prolink audio cable is a breeze. First, plug the 3.5mm stereo plug into your 3.5mm stereo mini speaker or other audio input device. Then, connect the iDock plug to your Apple device like an iPad, iTouch, iPhone, or iPod. You'll start enjoying high-quality stereo audio right away. As for maintenance, keep the cable away from sharp objects to avoid cuts. Also, don't bend it too sharply as it may damage the internal conductors. If the cable gets dirty, you can gently wipe it with a soft, dry cloth. When not in use, store it in a cool, dry place. And remember, this cable is specifically designed for Apple devices with an iDock and 3.5mm audio inputs, so use it only with compatible devices.
