I have a 20 gig nomad zen jukebox with a faulty headphone jack. Sound comes from one side only. If you wiggle or move the plug a little, it will change to the otherside, but not both sides. If you push the plug a little to one side sometimes you can get sound from both sides, but when you let go of the plug and not push, it goes back to one side only.
Thanks, Bob
