Hi, All.

I would like to know what it takes to adapt your basic pair of
walkman
headphones to a line level audio source, like on the back of a stereo
or perhaps a satellite TV box. Is it just a matter of putting a
series
resistor in there, or are we talking about transformers, op amps, and
power supplies? Does anyone make a commercial product for this
application? Ideally, it would be very small, and capable of routing
one line input to both heaphones (mono) or two line outputs to their
respective headphone drivers (stereo), and have a volume control.

One approach is to pick some fairly sensitive, high impedance
headphones. Sennheiser HD 580, and 600s come to mind.
