A:AnswerIf there is a headphone jack…yes you should be able to plug them into your tv. You may need to change the tv’s output settings to hear via headphone. And cord length may or may not be an issue depending on how far away from the tv you plan to listen from.
A:AnswerI don't see any hole for a jack on my iPhone. I am not certain but I strongly suspect that Apple declines to design their products for universal power supplies or audio sets and the like.
