This very brief guide will explain how I mended my Bose headphones but will refer to the other two guides here for images as I have none.

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.
-
-
-
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.

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.
-
-
-
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.

Refer to the other guides on how to disassemble the left side headphone which the headphone jack is inserted into. Once you have removed the headphone socket use a thin ended tool to bend the metal contacts at the end of the chamber (where the tip of the jack would sit). You can test if it’s making contact by inserting the jack whilst disassembled.
