Jbl roxy over ear headphones ref 430 need to install new cord. how do i open cans?
Headphone speakers stop functioning properly when the wireconnections to the speaker are broken. This problem often develops when theheadphone cord gets jerked while being worn. The solder connection might alsodetach over time if it was not properly manufactured. The wire can bereconnected to the speaker with a soldering iron to repair the headphone. Beaware, though, that headphones are not designed to be user maintained in thisfashion. In some cases, it is difficult to get to the speaker due to the casingdesign.
Instructions and tools needed
Screwdriver or butter knife (depending on headphone design),Soldering iron, Electrical solder
1 Plug in the solderingiron. It takes a few minutes for it to get warm enough to be used.
2 Unscrew the screws holdingthe headphone casing over the speakers. This step applies only to models thatuse screws in the casing.
3 Insert the end of the butterknife into the seam on the headphone ear pieces. Pry the two halves of thecasing apart. This step is performed only on headphone models that do not usescrews in the casing.
4 Touch the tip of thesoldering iron to the electrical solder. A small drop should melt onto the tipof the iron.
5 Touch the tip of the soldering iron to the end of thedetached speaker wire inside the headphone speaker cavity. Try to get an evencoating of solder around the exposed metal end of the wire. The soldersolidifies on the wire once the soldering iron is removed.
6 Touch the end of the wire tothe solder on the metal tab attached to the speaker.
7 Touch the tip of the solderingiron to where the wire and tab connect. The heat of the soldering iron meltsthe solder on the wire and tab together. This repairs the broken connectionbetween the wire and speaker.
8 Replace the speaker casingonto the headphone. It should snap back into place for models without screws
