A:AnswerHi David ,
It's the same technology as your cellphone . As long as you connect the earphones it's disconnects the tv speakers because the system is recognizing the need to connect earphones. If you want you can buy a splitter and connect your headphones and an external speaker/soundbar.
Hope I have answered your question.
Thank you

A:AnswerI bought mine from the weekly ad a few weeks ago. It was relatively low stock at that time. I haven't seen it in the newer ads and presumably they are out of stock. Typically they come back in again and would go on sale at some point.
