GE 98971 Headphones have a single cord extending from left ear piece to a power/volume-control device, then splitting into two separate cords: 1.) ends w/ yellow jack, 2.) ends w/ pink jack. The product manual does not describe these two jacks. Is there some industry-standard color guide for audio accessories that describes these two jacks? Which computer outlet port (e.g., mic or headphone ports) should I plug the jacks into? MATTHEW BLANCHARD http://gplus.to/matthewblanchard
