It’s not cost-effective for anyone to try and repair these things. Have you recently changed headphones? I know on new units we hear this complaint a lot; the jack is extrememly tight and the plug usually isn’t inserted all the way. Sometimes you have to twist while pushing very hard to get it to seat completely.
If you have new phones (or if the Fuze is new), this might also be the case. If not, it sounds like the jack has a loose connection. Unfortunately, there’s not much you can do is a case like this.
