I ripped off the wires from the control panel of my usb headphones and now i am completely lost especially at the input points of the control panel which takes the input from a wire which goes in the usb port of a computer.At the output i can see R=RIGHT L=LEFT GND=COMMON don't know about the other two M+ and M- and at the input side of the boad nothing is written where to connect which wire i don't understand please tell me how to connect these coloured wires on the input and the output of the CONTROL PANEL BOARD.I AM LOST!.

That looks like a digital signal processor DSP because of the crystal.

From the USB there is a ground, +5VDC and two high speed digital lines.

At the output each ear piece is two wires and a fifth wire, probably green, is an electrostatic shield.

Use an ohm meter to locate a pair of ear phone wires that have 1K to 25K resistance. To ID left / right put them on and touch wires with ohm meter and you will hear a faint pop in one ear.

USB pin out can be found on the web. A volt meter can ID the ground and +5 VDC which leaves two directional digital signal wires. Without a scope you don't know which is which. Maybe the web can pinpoint which is which or color or guess twice very briefly.

Do you know how to mark the best answer ?
