question on hooking up headphones help


I have an older set of Audio Technica electostatic headphones that plug into a little box that then plugs into your preamp. there are four wires coming out one white one red on black and one blue. what is the correct order to plug into my preamp? any helpers?

If I remember correctly those go to the speaker terminals on your power amp. Same color code as a phono cartridge.
Good Luck.
