We have a Digital HDTV that has no headphone jack, but I want to use headphones. The TV does have a single audio output jack. Would the output be compatible with Bose Headphones? How can the volume be controlled? The TV speaker needs to be off when using the headphones.
The RCA type jack that you are talking about on your TV is called a Coaxial Digital Audio Output Jack. In order to use your Bose Headphones on this TV you are first going to have to convert the Digital Audio to Analog Audio by using a Digital Audio To Analog Audio Converter/Decoder.
Since I do not know what brand TV you have I cannot tell you exactly how to shut off your TV speakers. Usually in the built in menu system of the TV there is an option to shut off the internal speakers and output digital audio. In other cases there is an actual switch on the TV that can be used to shut off the speakers.
Another alternative that would also improve the sound of your TV when you are not using headphones would be to use a Soundbar System or Home Theater System. Some of these systems also have built in headphone jacks.
The other advantage of these systems is that they will actually use the digital signals from your TV and convert them to the proper surround sound format which will enhance your sound experience when not using headphones.
