My headphone (Sennheiser HD 265) has a socketed connection between cable and headphone. The headphone cable had come loose, so I bought a new connector and soldered the headphone cable to it.
The connector looks like this:
Now, the soldering worked fine. However, I don't know how to mechanically secure the cable to the connector. I initially tried just soldering it and letting it leave the connector via the small plastic "tube" (strain relief) on the left side, but it turned out that the cable will be pulled and, worse, twisted when the headphone is in use, which causes it to come loose.
How can I secure the cable against pulling/twisting?
- squeezing the "tube" part of the connector so it holds the cable
- putting sticky tape across cable and connector
but that was not sufficient.
