Question about Sennheiser PXC 250 Consumer Headphones
I have the PXC 250 headphones and I'm reploacing the connector. It's not stereo. There's 3 wires: red, green and copper. which is left, right and ground and any special conditions when resoldering? thanks, Ray
My jack plug lead got yanked and broke the wires inside the electronics unit. There are three screws to undo in order to get inside the electronics, one by the cable entry and two very small cross head scvrews in deep holes halfway along the unit. I cut the jack lead on the outside close to the cable entry and drilled out the hole through the cable guide and then poked the jack cable back through the hole into the electronic unit. I was able to solder the three leads to their respective pads. There are five solder pads next to the cable entry. With the cable entry at the top, the middle pad connects to the green cable, the rightmost pad connects to the red cable and the copper connects to a pad about 1 cm down from the rightmost connector. The technique was to tin the ends of the leads with solder before soldering them to the pads. I used a blob of glue from a glue gun to hold the cable in place inside the electronics unit. My plan B if the soldering was not possible was to take a jack plug and lead from an unused set of earpieces and use that lead in place of the original. It would have been much more difficult to replace the lead from the electronics unit to the headset.
