Using your Prolink Curly Audio Cable is easy. First, check the 3.5mm stereo plugs at both ends of the cable. Plug one end into the audio output jack of your device, like your portable CD player or iPad. Then, plug the other end into the audio input of your speaker or other audio device. When you're done using it, you can gently coil the cable back up. As for maintenance, keep the cable away from sharp objects that could cut the outer PVC jacket. Also, avoid bending the cable too sharply as it might damage the inner conductors. If the connectors get dirty, you can use a soft, dry cloth to gently wipe them. That's it! With proper use and care, your cable will last a long time and keep delivering great audio.
