The tools and parts that you will need for this repair:
- A New Battery
- 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)
- Repair Kit (Contains tweezers, and the flat head and Phillips head screwdrivers)
- A Small Phillips Screwdriver
- A Small Flat Head Screwdriver
- Some Precision Tweezers
- 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.
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 Battery Cover
Start by removing the 4 silver screws that hold the battery 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.
3. Removing The Battery
Lift the black and red wired battery connector out of its plug in the PCB by gripping the two wires and pulling straight up.
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.
4. Install The New Battery
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.
Reinstall the orange ribbon cable first by gently grasping the end of it with two fingers and sliding it down into its connector.
Reinstall the white touchpad ribbon the same way using your fingers and gently sliding it into its connector
Reinstall the battery connector making sure to align the two pins in the connector with the spacing on the plug as they are not centered in the plug.
Using your flat edge screwdriver, push the battery cables down into their routing groove to make sure they are out of the way.
5. Reassemble The Headphones
Place the touchpad cover back onto the headphones and make sure that there is no gap around the edge of it.
Reinsert the four silver screws into the speaker housing.
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.
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.
