Step 1 Repairing Bose On-Ear headphones Wiring




• Here is the Bose Tricore OE headset. Slightly worn, it does not produce any sound to the right side driver

Step 3
• The first two screws are longer than the two from under the padding, so keep them separate.
• With the screws removed, the driver (speaker) can now simply removed by just folding it over.
• There is a small PCB to which the driver (speaker) mounts. Check the solder connections of the driver (speaker) to the board, as well as the components on this board. It consist of a few caps, resistors, and a coil.

Step 9
• Check the driver (speaker) the same way as on the left side.
• On this headset, both drivers worked while being tested, but not when the audio was connected to the audio jack. The jack needed to be replaced.
• Desolder the audio jack cable by using a soldering wick. Apply flux to the wick prior to unsoldering.
• Remove the old audio jack cable.

Step 10
• Here is the rubber boot that holds the audio jack cable in place.
• Insert the replacement cable as shown through the boot. Solder the new cable to the PCB.
• Reassemble the headphones after double checking the solder job. This one also received new ear pads (readily available at online auction sites) and works perfectly.
