Subject: Connecting Headphones to RCA OUTPUTS?

Thanx Art, but as a matter of fact, looked at a few of
these
on the web (eventually did buy a decent Sennheiser to
use
only for my cd player and stereo system) but all I found
used a pin headphone jack on the charging unit to plug
into
the output from the electronic equipment desired--IOW,
just
what I lack on my tv and vcrs. I suppose, if I
understand
what you're saying, then is all I should need maybe is a
proper adaptor to connect the female L/R RCA output
jacks on
tv or vcr to the male pin plug on the charger unit ...
huh?
Or do I have the voltage/current spec mismatch
backwards.
(Also, then there's only the volume adjust on the
headphones
to control any voltage/current mismatch, which sounds ok
I
guess, right?) If so, will have to talk to Radioshack
guys
to find if such is available--I don't readily see any
such
type of adaptor at the RS web site, but their search
engine
is terrible. Thanx again, ...tonyC


First, I from your post, I cannot tell if the input to the
wireless
headphones is 1/8" male or 1/8" female. If it's 1/8"
female, an adapter is
widely available.

Yes, I saw that adaptor, but unfortunately, my input to the
WH is a miniPhono, I guess 1/8", but it is male--which is
what is throwing me for a while.

It is sold as a 1/8" to RCA cable -
often used (or
marketed) to connect a portable device (ie CD player, MP3
player) to a home
stereo system. The 1/8" connector is used to connect to
the CD player and
the RCA to the amplifier. In your case, the 1/8"
connector connects to the
input of the headphones and the RCA to the amplifier.
When you go to the
store, just ask for a cable to connect your portable
device to the
amplifier. (Cables are bi-directional, so 'sound' can
'flow' from A to B
and also from B to A).

Thanx--I thought that would work but wasn't sure. Now I just
need the right adaptor(s) as you note below. Sometimes ya
just can't find stuff like that in the web site search--pays
to mosey down to Radio Shack and ask for it...which I'll do
ASAP.

If the input to the wireless headphones is male, you will
have to do some
searching for approprate connectors. (None come to mind
right now) It may
take a combination of a few different connectors.

The volume control of the headphones does not control the
input
voltage/current. The controls on the headphones only
change 'stuff' that's
in the headphones. Since the wires are not connected to
the headphones,
this control doesn't affect the input signal. It does
affect the volume
though, so you would use these to control the volume.You
should be fine with
the voltage/current ratings however the headphones might
have a low input
impedance which would load the VCR(was it?). But this
shouldn't be too big
of a problem.

Yes, thanx for clearing that up--it's been much too long
since I tried studying electronics.

If you already own a pair of wireless headphones, use them
as you don't have
to worry about being teathered to the equpment.

Yep--this will be a great way to go... if'n I can only get
that
@##$%^&_!@ adaptor! At least I understand the options now
and what I'm doing. Thanx again Jeff and y'all here for your
help! ...tonyC
