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!

Line level outputs generally don't provide enough power to drive headphones.
Headphones vary tremendously in sensitivity and impedance, so you might find
some that work in some applications. The best way to do what you want to do
is to purchase or build a headphone amplifier. They range in price from
probably under $10.00 for el-cheapo, to ca. $100.00 for a good quality unit,
or $1000.00 for audiophile gear. You might want to pay a visit to HeadRoom
(http://www.headphone.com/layout.php?...&subTopicID=27). They cater to
the headphone enthusiast.

Line level outputs generally don't provide enough power to drive
headphones.

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.

Usually you'd buy a headphone amp.

Sometimes you can find high impedance headphones too. 32 Ohms is common
and 64 Ohms may exist. Some line level outputs have 100 Ohm impedance,
which could drive 32+ Ohm headphones with a usable volume.

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