Adapt walkman headphones to line level source?

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

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.

Thanks much!

Gary Watson

But sometimes you get lucky. Some line-level outputs have sufficient
power, and some headphones are sensitive enough to work directly.
Of course, volume control may be an issue.

Some AKG headphones are 600 ohm, and are designed for that, but usually the
easy way is to use a headphone amp.
