A:AnswerThe transmitter has to be powered, 120v, and audio cable connected to source, assumed to be your tv. So, wherever your set, cable box, dvr, etc. is powered plug it in there and run audio connection between transmitter and audio source.
A:AnswerOnly if you have an optical out, head phone out, or RCA red and white outputs on tv. If only head phone out, you can buy splitter wire to RCA red and white lines.
A:AnswerI'm not sure that this can be done. I use some elasticized terry cloth headphone covers. They can be washed whenever. I found mine on an aviation website and they were too expensive, but they work.
