Hello!
I have an aviation active noise cancelling headset Sennheiser HMEC 26-2. Recently I had an accident with this headset. While getting of the seat and out of the cockpit the cable was wrapped around my leg. When I stepped out the whole right speaker seperated from the rest of the headset and the wires got seperated from the solder joints.
I know how to solder but the wires are very thin so I plan to give the headset to some soldering specialist. Luckily all the plastic parts are intact and there is no structural damage. All that has to be done is to resolder those 5 wires.
I disassembled the right side (speaker). But there is the problem - there are no markings on the PCB solder pads (I checked the both sides of the PCB) and I know almost nothing about audio equipment. There are 5 wires - black, red, yellow, blue and green. I think these wires connect the left and right side of the headset. Does anyone know where can I get the wiring diagrams? Should I open the left side of the headset and check how the wires are soldered? Do you think the wires in the left side are soldered to the same pads as the wires in the right side?
There is also a short wire with green isolation soldered to one of the pads. It also has no signs of solder on the other end. I think this solder pad and the wire serve no purpose on this side of the headset.
Any help will be greatly appreciated!
