Headphone question

[r***@optonline.net]

Probably a stupid question to the more technically savvy here but I'm not one of
them.

I have a Sony Bravia TV to which I've had a pair of Senheisser heaphones hooked
up. That's about the only way I listen, as we live about 200 feet from an
Interstate and the noise, especially when the windows are open during the nice
weather, is not conducive to listening through the speakers. The headphones are
hard wired. And they're always on an end table at one end of my sofa.

I decided to get a second pair of headphones, also Senheisser, for the other end
of the sofa so if there's two of us watching TV.

I connected the two sets to a "Y" splitter which comes out of a cable I have
coming from the TV set.

I've noticed that now I have to turn the volume up higher using either set of
headphones. Is this because of two sets connected to the one cable?

Like I said, I'm not technically savvy, but I figured it's like the power in my
house. 110/120 volts in, and the same 110/120 out of any outlet in the place, no
drop in power. Am I wrong? Also, even at the same power level, the new
headphones seem to need a little extra volume than the originals. Is this usual?
Thanks.

The power line in your house has a very large amount of
power available. Hooking more things up to it doesn't
reduce the power available to each of them by a detectable
amount. The output of your TV has a limited amount of power.
So hooking 2 head sets up to it reduces the amount of power
available to each one by about half.

You have also lowered the impedance load presented to the amplifier,
which can change the amount of power it puts out.

Look for 'powered headphone splitter' or 'headphone amp'. There are lots
of little boxes that can plug into your headphone out on your TV, and
drive two or more sets of headphones. They will either have their own
power supply or use something like a 9v battery for power.

Thanks. You mean something like this:

Or this, although with this one it looks like I'd have to use adapters on the
plugs so theyd fit:
