A:AnswerMy son just purchased this TV. He really likes the quality of the picture, but he can't use his wired headphones because there is no jack for plugging them in. His Bluetooth headphones do work with it just fine, but he doesn't like to have to keep recharging them. He will probably purchase an adapter so that he can plug in his wired headphones.
A:AnswerIt does come with wall mount, almost all new tv's do. The cable is a few feet long. It should be able to reach an outlet (since most tv's are placed in a room near an outlet anyways).
