Hello. For my HDTV, I have Sony's HT-SS370 surround sound system. Unfortunately, it doesn't have a headphone jack. I would like one so that I can listen to music on my phone, computer, or anything else that uses 3.5mm headphone jacks. What cable do I need to accomplish this? Here is a picture of the back: http://www.mcmelectronics.com/content/productimages/s4/ht-ss370_2.jpg In words, see page 2 here: http://www.docs.sony.com/reflib/docget.asp?manualid=1076784&template_id=1®ion_id=1&DL= Is this an option?: For only $0.65 each when QTY 50+ purchased - 3.5mm Stereo Plug/2 RCA Plug Cable - 6ft | 3.5mm/RCA Audio Cables Thank you all!!!
