Bluetooth Ground Wire Shell Removal

Lift the left earpad (labeled L) straight up and remove it.

Insert a SIM eject tool, bit, or a small, straightened paperclip into the hole on the top edge of the right ear cup (labeled L).

Push down with your tool and pull the headband connector straight out of its socket.

Set the left ear cup down on a soft, clean cloth to prevent scratches and help stabilize the cup during your repair.

Use a P5 pentalobe screwdriver to turn (not remove) the four speaker housing screws to the unlocked position:

Turn the top left and bottom right screws counterclockwise.

Turn the top right and bottom left screws clockwise.

Option 1: Apply a few drops of high-concentration isopropyl alcohol (>90%) in the gap around the perimeter of the speaker housing. Wait one minute to allow the alcohol to soften the adhesive.

Option 2: Heat the speaker housing with an iOpener or hair dryer. Focus the heat around the perimeter, applying small amounts for short periods of time.

Insert the flat side of your opening tool into the gap between the right side of the speaker housing and the lip of the ear cup (opposite the L marking).

Pry up the speaker housing until you can grip it with your fingers, applying constant pressure to allow the adhesive to separate.

Lift the speaker housing out of the ear cup to fully separate the remaining adhesive.

Flip the housing over the side of the cup and prop it up so you can access the cable.

Option 1: Stick a small flathead screwdriver into one of the four notches on top of the screw and use it to slowly turn the screw.

Option 2: Use a Torq-Set 6 screwdriver to remove the screw, applying constant downward force to avoid damaging the screw.

Lift the right edge of the speaker and remove it, being careful not to touch the diaphragm.

Slide one arm of your angled tweezers under the metal neck of the coaxial connector (next to the one from the previous step) and lift straight up to disconnect it.

Use the point of a spudger to gently pull the copper hinge cable (in plastic tubing) out of its clip.

Use a Torx Plus 1IP screwdriver to remove the 3.0 mm‑long screw securing the Bluetooth board.

Stick the point of a spudger into the baord's screw hole near the hinge and pull the board towards the center of the ear cup.
