A:AnswerIf I understand your question,the transmitter for these headphones is powered by AC. I have both the TV and transmitter plugged into a surge protector.
All the cables and adapters needed to connect the transmitter to the TV are provided with the unit.
A:AnswerWe have an LG smart TV that doesn't have audio output Jack's. So,we can't hook up our headphones. Why they make such an expensive TV with no audio output is kind of unbelievable. We do have a tivoli that does have audio output so anything coming thru it we can use headset. Unfortunately,that excludes all over the air broadcast channels.
A:AnswerAs seen in the picture, these headphones cover the ears. The headphones don’t go above or behind but, like an overcoat, they fit over the ears.
