If you go and buy yourself a cheap set of earphones, you can cut off 1 of the earpieces and strip the wires. It can be a little difficult as the 2 wires are usually very thin. You may be able to hook up the 2 wires to the violet/slate pair directly, but I find it easier to splice some jumper wire onto it and tape it up. Use the jumper wire to connect to your pins. Then just plug it into the headphone jack of your CD player and program music on hold, and background music if you want it to come through the telephones. Remember too, that the pins you hook up to vary from system to system. If you have an 8X24 that`s ok, but if it`s a different norstar system, let us know and we`ll tell you what pins to use.
