You'll use this cable to connect your iPhone, iPod, MP3 player, iPad, laptop all kinds of devices with headphone jacks or line-out jacks to the AUX-in port of your car stereo, the mic jack in your home entertainment system, and all kinds of audio jacks, everywhere.
After reading the reviews on a couple of stereo cables, I decided to purchase this one. I like the flat design-stores compactly. The sound was good. I have no complaints. The product arrived quickly and not to mention the (sale) price was a steal.
