      • Removing the ear cup isn’t required, but can make the repair easier. You can leave the cup attached and remove it later if needed.

      • 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.

      • The headband connector should slide out easily. If you're having trouble, reposition the tool and try again—you may need to angle the bit slightly.

    2. Bluetooth Board Removal, Turn the housing screws to the open position: step 4, image 1 of 2 Bluetooth Board Removal, Turn the housing screws to the open position: step 4, image 2 of 2
      • Turn these screws slowly and gently, stopping when you feel resistance—about 1/4 turn. If turned too far, the locking mechanism will break.

      • 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.

      • The perimeter of the speaker housing is secured to the cup with adhesive. This step shows a few methods to soften the adhesive so you can pry up the housing. If one isn't working, try a different method.

      • 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.

      • Don't heat the center of the speaker housing, or you'll damage the fragile mesh under the speaker cutouts and possibly the speaker.

      • For a detailed look at best practices for using a hair dryer, check out this guide.

    4. Bluetooth Board Removal, Pry up the speaker housing: step 6, image 1 of 3 Bluetooth Board Removal, Pry up the speaker housing: step 6, image 2 of 3 Bluetooth Board Removal, Pry up the speaker housing: step 6, image 3 of 3
      Tool used on this step:
      iSesamo Opening Tool

      Buy
      • The gap between the speaker housing and ear cup is extremely small. You'll need a thin tool such as a metal opening pick, iSesamo, or iFlex to pry up the housing.

      • Don't grip the iFlex or similar metal tools by the edges—they're sharp and may cut you. Consider wearing gloves to protect yourself.

      • 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.

      • If the housing isn't coming up, repeat the previous step and try again. Don't try and force the housing out or you may damage it.

      • Don't try to fully remove the speaker housing yet—a delicate ribbon cable still connects it to the ear cup.

      • 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.

      • Three 1.7 mm‑long Torx Plus 1IP screws
