This repair will require you to use a screwdriver and a soldering tool to remove certain components of the headphones. Only use this guide to replace damaged speakers that affect the output audio of the device. This repair should take roughly 30 minutes to complete.
Remove the foam pads by twisting them counterclockwise.
The pads should release from the grooves that are housed on the speaker inside.
There should be approximately three screws holding the right speaker. Unscrew them to gain access to the wiring of the speakers.
Keep the screws in a safe place. They are small and can easily be lost.
Leave the desoldered and unstripped wires for the next step.
Follow the instructions in reverse to put together the speaker in the housing, as well as the foam pad over the speaker.
Make sure to pack in all of the companents back into the housing when finished with this step.
