I should have read the description more carefully and not just the illustration. When I ordered this connection kit I was expecting some kind of simple docking device for the iPod into which the leads connected, using the line-out connection from the docking connector. But the kit contains just standard jack-to-phono leads which plug into the headphone socket, the docking unit shown in the picture is not included. That said, they work fine and for the price I'm not complaining. To get an appropriate level of signal to your stereo system you will probably need to increase the volume limit settings of the iPod - this will increase the maximum sound level in the earphones also.
