Repair Difficulty: Difficult 

Time to complete: 1-2 hours

The tools and parts that you will need for this repair:

  1. A New Power Board
  2. Strong Pry Tool (a guitar pick, or the dull side of a butter knife can also do the trick. Just be careful to not scratch the inside of the headphones)
  3. A Soldering iron (A 15 watt one would do the trick and save some money over a temperature variable unit).
  4. Solder (Very small amount if any)
  5. Solder Flux
  6. Repair Kit (Contains tweezers,  and the flat head and Phillips screwdrivers)
  7. A Small Phillips Screwdriver 
  8. Small Flat Head Screwdriver
  9. Some Precision Tweezers
  10. Anti-Static Parts Organizer Mat



    1. Remove the Ear Pad

    Insert your pry tool between the ear pad and the headphones just above or below from the center of the side of the ear pad. There is a clip in the center that holds the ear pad in place. Prying directly on the clip could break it and keep your ear pad from attaching properly.

    Lifting the ear pad with your pry tool

    Be careful to not damage the clips


    Once you lift the ear pad up on one side, you can use your hand to pull the ear pad away from the headphones. There are a few more clips so just pull and wiggle at each clip to unhook it.

    Lastly, set the ear pad to the side and remove the foam from the center of the speaker and set it with the ear pad.

    2. Remove The Touchpad Cover

    Start by removing the 4 silver screws that hold the touchpad housing in its place.

    Insert your small flathead screwdriver into the crack between the battery cover and the headphones shell and gently pry the battery cover up.

    Once the cover is loose, you can use your fingers to remove it the rest of the way. Be careful as the touchpad is connected to the headphones still via a ribbon cable.

    Remove the ribbon cable that attaches the touchpad by gripping it between two fingers and gently pulling it straight up and out of its socket. Once it's removed, just set it to the side.

    Using your flat head screwdriver on one side and your fingernail on the other, lift the orange ribbon cable out of its connector on the PCB by gently pulling up. *There are grooves near the bottom of the ribbon cable where it is safe to put your screwdriver, make sure that you do not put it on the fragile upper part of the cable.

    Using your strong pry tool, pry up the battery from the top side. It will take a couple times of prying and lifting for the adhesive to come loose.

    Once the battery is lifted part way, you can use your fingers to lift it the rest of the way off the headphones shell.

    Remove the main wire connection to the power board using your fingernail and the small flat head screwdriver, both placed under the tabs on the sides of the connector. These tabs break very easily so be careful to apply even lift pressure to both sides and pull the connector straight up out of its socket.

    4.  Install The Power Board

    Connect the new power board to the white ribbon cable that sticks up through the headphones shell. It is easiest to use your tweezers to gently slide the ribbon into the connector. The dark line in the blue part of the ribbon should disappear inside of the connector.

    Reinserting the white ribbon into the power board


    Seat the power board into its place in the shell by moving the wires out of the way and wiggling it until it seats well and the screw holes are aligned with the screw studs in the headphones shell.

    Apply a small dot of flux to each of the 6 solder points on the power board.

    Resolder the 6 wires to their points using your tweezers to hold each one in place. You may need to add a bit of solder to your soldering iron's tip in order to have a good connection on the board. 

    Start by soldering the copper wire of the speaker wire to the innermost connection on the set of two on the board.

    Re solder the black speaker wire to the power board


    Reconnect the black ambient noise cancellation microphone cable with the copper wire on the upper pad of the middle set of pads on the PCB and the red wire on the lower pad.

    Place the new battery into its tray, making sure that the two wires are facing the same directions as there were on the old battery. 

    Placing the battery back into its tray


    Reinstall the orange ribbon cable first by gently grasping the end of it with two fingers and sliding it down into its connector.

    Place the foam back into its place lining up the flat bottom of the inside of the speaker cup with the flat part of the foam. 

    Place the foam back into the speaker housing


    Line up the clips with the holes in the speaker cup. The cutout in the top right corner of the ear pad goes to the top left of the speaker cup. Press down on the edges of the ear pads to connect the snap connectors. 

    Line the clips on the ear pad up with the holes in the speaker housing

    This cutout faces up and to the left when the ear pad is placed on the speaker
