On the RS120, I think you are telling me that the charger is also a transmitter and that nothing else is required?

Correct. And you'll hear subtle sounds that you don't hear when listening to TV--even if you have a sound bar--when not using headset. I use the RS120 even when I don't need to, i.e., even when no one else is around.

These cancel out the TV speakers. What if I want to use TV speakers, must they be unplugged or is there a switch?

If your TV has an optical TOSLINK socket or coaxial output get this. https://www.amazon.com/gp/product/B00T3ZRI44/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1. No static, TV and headphone speakers both work. You can use the TV volume to control the TV and the volume and switch on the headset to control it.

can other people still hear the the tv if you are using the headphones with a Phillips tv

Our Toshiba TV has on-screen settings menus that allow cutting off the speakers while leaving the audio jacks active. But there are a few menu steps, which gets to be a nuisance when executed 5 - 10 times in an hour. So instead I plug the RS120 base transmitter into the Directv satellite receiver., which allows use of the headset with the TV speakers muted -- or even with the TV turned off. (One tiny issue with that arrangement: the receiver audio and the TV audio are not perfectly synchronized, so if you elect to use the headset while the TV speakers are on, you get an echo effect.)

Is the sound quality good when you have on the earphones and someone else is in the room watching the same program. Is there a time delay or feedback

The sound quality is very good, and there is no time delay or feedback. You can use it even when the TV is in mute mode, not like some other earphone is dependent on the TV sound level.
