I have no clue what to call it, but I saved a plug from a trash circuit that allows you to plug a set of headphones into it ( a little help on the name would be awesome)

(please forgive me for any errors I'm a youngster)

As for how to connect it is a mystery. I have tested it every which way and I still cant seem to hook it up right. From what I have gathered so far is that two wires (carrying the signal) seem to hook up to one pin and the power/RL channels seem to connect to separate ones

(possibly mislabeled)

but then there are two pins that seem to do nothing.

 

Could that possibly be a 3.5mm audio connector? There are also 2.5mm or 1/4" in addition to the 3.5mm. For headphones, it would have to be a stereo connector.

 

Would it be possible to photograph the connector in question and attach the picture here?

Alright, I have added 3 pictures of it. (sorry for the size of the pictures, but I uploaded directly off my camera.)

 

That is normally called a jack, not a plug, and one pin is common ground, two are L, R and two are normally closed cancelling contacts; used as to disconnect speakers when an earphone is plugged in.
Probably taken from a stereo or PC audio card.

 

Well thanks, but that doesn't seem to answer what the other unkown pins are.

 

Sorry, poor typing.

One common, one L, one R, and two normally closed contacts to L, R, make five pins.

 

Thanks!

Now, can any one give me a basic audio circuit that is by-passable by a pair of headphones? (I have a hard time doing this)
