Use the Phillips #00 screwdriver to loosen and remove the screw holding the inner headphone cover in place.

The screw dimensions are as follows: Length to Head = 4 mm, Head Length = 1.5 mm, Head Diameter = 3.5 mm, Major Diameter = 2 mm, Pitch = 0.5 mm.

All steps can be followed on both the left or right side of the headphones to remove inner coverings.
