A:AnswerHey there, your speakers have three stereo RCA audio inputs, three Coaxial digital audio inputs, one Optical digital audio input, one 3.5 mm for FM 75 ohm antenna, one Composite video input, and one S-video input for connecting to other devices.
A:AnswerWe listen to YouTube videos as well and are very pleased with the Bose. Our LG TV is about 9 years old and we just used the cable that came with the unit. The sound is great.
A:AnswerNot sure about headphone jack. You should connect your Bose to your TV via HDMI cable in the HDMI port labeled ARC on your TV (real important you use this specific HDMI port). If you do that, you should be able to pair the speaker to the Xfinity remote relatively easily.
A:AnswerHey you can use your dish or Direct TV remote to control your Sound Bar and TV, no need
to go out and buy a new. But as a reminder, keep it out of view from the Family Dog...
A:AnswerYes this speaker comes with two cables one is optical you can connect it that way or the other is HDMI and it would connect to the arc outlet on the back of the tv either way works.
And you can bluetooth your phone to the speaker to play music from it. We do this at night to play rain and thunder while we sleep
