They are pretty much the most amazing sounding headphones ever, and they have this weird soft rubber earpiece that blocks out alot of outside sound and they stay in pretty well.

They're reasonably priced too: $15.00
Places like Target, Staples, and FYE sell them

In the wire for headphones...red, yellow, and white stand for right, left, and common.?

I dont know which is which thhough


Answer
I assume you have a headphone only. No microphone, nothing to do with video, etc. There are unwritten common colors, but depending on where it is made these may not be adhered to. I assume you have three wires and want to determine how they are wired. If you cannot get to where the wires connect to the driver in the headphone, you can take a battery, say an AA (1.5v) and drive what you think are the left two with the voltage going through a resistor. If you are correct in selecting a proper pair, you will hear a scratching sound in the correct side.

The proper way to determine the resistor is to determine the sensitivity of the headphones (usually listed in mV), and devide the battery voltage by half that level (half for additional safety). If you do not know what the sensitivity is, start with a 1k resistor.

So you would go positive side battery to red, negative battery through resistor to other color (I would try yellow first), while listening to the headphones. If you do not hear anything try white instead of yellow. If you still do not hear anything, reduce the value of the resistor. Note it will only make noise when you touch the wires. Do not touch and hold the power on. Headphones only make noise on change of voltage so you need to keep making and breaking contact in the wires. If you hold the power on continuously you may overheat and ruin you headphones.
