Description: Prerequisite guide to disconnect the...

Remove the All-In-One Cable from the cable guides along the left side of the head strap.
During reassembly, connect the All-In-One Cable to the headset before routing it through the cable guides. This will ensure it has the right amount of slack.

Feed the top strap through the clip near the front of headset to fully remove it.

Use the point of your spudger to pry out the two rubber spacers next to the headphone screws.
Be careful not to accidentally pry any of the speaker wires under the rubber spacer.

Use the point of your spudger to pry up and disconnect both the left and right headphone speaker wires.

Use a T6 Torx screwdriver to remove the two 12.1 mm screws (one on each side) securing the head strap to the headset.
Use a T5 Torx screwdriver to remove the following screws securing the head strap to the headset:
Four 3.9 mm screws (two on each side)
Two 4.1 mm screws (one on each side)

The four screws securing the outer shell are covered with black stickers. If the stickers are difficult to remove, simply press your T6 Torx driver through them.

Use a T6 Torx screwdriver to remove the four 3.9 mm screws (two on top, two on bottom) securing the outer shell to the headset.

Insert an opening pick into the seam between the two halves of the outer shell.
Slide the opening pick through the seam to dislodge the clips securing it to the headset.
Only insert the opening pick as far as necessary. There are ribbon cables underneath the outer shell.

Continue sliding the opening pick through each seam until all clips have been dislodged.

Use the point of your spudger, or a clean fingernail, to flip up the locking tab on the microphone ZIF connector on the daughterboard.

Use tweezers, or your fingers, to pull the microphone cable straight out of its socket.

Use tweezers, or your fingers, to peel the conductive fabric off the sensor array ZIF connector on the motherboard.

Use your spudger, or a clean fingernail, to flip up the locking tab on the sensor array ZIF connector.

Use your fingers to grip the left and right sides of the sensor array cable and pull it straight out of its socket.

Use a T5 Torx screwdriver to remove the four 3.0 mm‑long screws securing the top of the sensor array.

Use a T6 Torx screwdriver to remove the four 3.8 mm‑long screws securing the front of the sensor array.

Lift the sensor array straight off the lens assembly and remove it, making sure you thread the cable through its slot.
During reassembly, make sure the sensor assembly cable is threaded through its slot before continuing.

Use your fingers to peel up the thermal pad covering the daughterboard.
The thermal pad will likely remove the Kapton tape from the ZIF connectors on the daughterboard. Replace the Kapton tape if necessary.
Set aside the thermal pad. You'll reuse it during reassembly.

Insert the flat end of a spudger under a corner of the lens assembly press connector.
Don't insert your spudger anywhere else, as you risk dislodging nearby surface-mounted components.
Twist the spudger to lift the press connector up and disconnect it.
Repeat the same process to disconnect the other lens assembly press connector.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down in the middle. If the connector is misaligned, the pins can bend and cause permanent damage.
