A:AnswerThere is no bluetooth connectivity for this tv. You could buy a roku and use that for streaming services and use the roku app on your phone to connect to wireless headphones. But there is no way to connect directly to the tv itself.
A:AnswerYes. We have plugged in our Prime Stick and my husband uses that one. So fewer buttons to deal with. All you do is hit the Source button on the new tv remote (top right hand corner) and pick whichever HDMI plug you used and you will now have to use the Alexa remote.
A:AnswerI believe the remote control sensor is located bottom middle area of the screen , there is a red led light under the tv that glows when tv is powered off . By the way the volume is super loud on this tv compared to the lg led tv we owned previously.
A:AnswerYes, you could use a Roku on the tv instead of the apps but that kind of defeats the purpose of a smart tv. You could probably find one that isn’t a smart tv, install your roku and save a few dollars.
