My Sennheiser HD25-1 ii have developed the problem where the speaker connectors need to be jiggled or plugged in a few times to get a good connection. This was becoming so bad that in the end I couldn't even get the left headphone working properly at all.
I decided to open them up to check if I could tighten the spring inside or maybe just solder the wires in and discard the plug altogether.
Well now the soldering has become a must as I broke one of the voice coil wires..very good explanation of what has happened here:
So any suggestions for soldering the voice coil wire in?
Seems the voice coil is aluminium...which might mean soldering isn't even an option...
Any help greatly appreciated!
