Will not play downloads, which came "free" with the purchase.

My husband and I purchased matching lyric mp3 players from F.Y.E. for Christmas for each other. My Mp3 player works just fine. It plays the downloaded music and all my music from my cd collection. I went to the emusic website and signed up for the "35 free song" downloads. Downloaded what I liked to my cumputer and then synched them to each of the players. Mine play with my earphones or via the computer. His player will only play them if it is hooked up to the computer, not through the earphones. I have tried eveything short of returning the player to the store. Has anybody else had this problem? My name is Rita and am needing some help, badly!
