Einleitung

This is truly a quick and dirty guide to the repair of the wiring. This Bose headset is pretty straight forward. Of course, I will clean it up and make it a bit more presentable.

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

    • Remove the ear pads by simply applying a bit of force between the ear pads and the housing. The ear pad will simply snap off

    • This shows the snaps that attach the ear pad to the case.

    • With the ear pad removed, the Phillips screws that hold the drive to the case, are now visible.

    • Remove the two screws on top

    • There are two more under the padding on the bottom. Remove those as well.

    • 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.

    • Since both driver (speaker) wiring will be checked, remove the left ear pad as well.

    • Same screw configuration. Two screws on top,

    • two screws under the bottom pad,

    • The Phillips screws are identical and do not need to be separated

    • Remove the driver from the case by simply flipping it to the side.

    • Same PCB on both sides. Check the solder connections from the driver (speaker) to the PCB.

    • Here is the PCB of the right side driver (speaker)

    • Simple setup to test the driver (speaker) Two leads with alligator clips, connect those to an 3.5mm audio jack extension.

    • Use those leads and touch the connector of the driver (speaker) on the PCB. There will be sound if the driver (speaker) is working.

    • Remove the driver (speaker) from the case

    • Make note off how the audio jack cable is fastened.

    • Remove the audio jack cable from the case. It is simply a rubber plug that is pressed into the case.

    • 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.

    • 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.

Hi - Thanks for the guide. I have a left earphone not working, what can I deduce from that? everything looks ok on the right side. Guess it can be the audi jack cable?
