Connecting TV to wireless headphones

Archived from groups: rec.audio.tech (More info?)

I need some information on buying a TV for someone who is hard of hearing
and wants to listen to the TV with wireless headphones (Sennheiser RS-120).
The TV needs to have the correct type of jack to plug in the headphones base
unit, but in reading specs of TV sets it isn't always clear whether they do
have the right jack, which is an RCA type. I have seen one or two that
specify RCA, but others will just say "Audio output" or "A/V output". I 'm
not clear if this is the same thing and would like some guidance on what to
look for.

What do you mean by the electrical spec?

Right. If the TV has a headphone (or line) output, the physical jack
does not matter as you can get an adapter to change it to what you
need.

I read the spec sheet and checked out the headphones in a store. They do
connect
to a standard headphone jack or an RCA jack. It seems that virtually no TV
set has an
RCA output and maybe half of them have headphone jacks, at least toward the
lower
end of the TV price spectrum. I'm quite surprised at how many TV sets aren't
equipped
for this kind of connection.
