I don’t have a new player suggestion but to revive your old player. TYou said the headpjone jack wasn’t working. Get a Q tip and some Iscypropal rubbing alchohol remove about have the cotton from one end of the Q tip and shove it in the jack and give it a good scrub then try it and see if it works.
Because hey why buy a new MP3 player when you can fix the old one and spend the money on something else.
