Last night, I have two headphones (cable) repaired mitttels this jack. Go As with most headphones this always because cable break (loose contact, then usually lacks a channel) broken. The implementation of the repair succeeds with this jack. A deduction of points there, because the "Anlötzunge" for mass break very easily, making it difficult soldering. When soldering should set the soldering points sparingly, since otherwise not the housing of the jack gets assembled. If you have applied too much, careful again carefully "flatten" the soldering by soldering iron. So I proceeded: First, the Massedrähtchen soldered (at Philips headphones colored blue) then the minus wire strands soldered (red color) and the soldered the latest to be two + small wires (copper-colored) one channel. Before assembling testing whether the headset is working and then assemble -Here make 4 hands paid including two small flat-nose pliers! Important: The interior as Kunstofftrennung must -also if that is to be installed fumelig, is important because so including cable jacket edged certainly end in the area after the rotation the threaded plug cable! And do not forget: The rear part of the plastic cap with the cable gland (see image advertising!) Must first of all as though are threaded through the solderable Kopfhöerkabel -and the correct direction, with the direction schrazen rubber headphones. I have previously even a matching heat shrink tubing (must have the rear headphone jacket suit) threaded and at the end of the repair and the careful heating of the shrink tube additionally protects this as the headphone cord and that because it always breaks! Incidentally, it is a pity that there is no such as a three-pole Neutrik plug straight plug, I would rather have a car!
