Assembly Instructions

   1. Make not of which side is Left and Right - this will matter later
2. Insert the six (6) M2 nuts into the bottom half of each adapter piece

3. Slide the printed adapters on the exposed headset speakers.
   1. The prints are designed to fit snugly into the existing slots
4. Secure the adapters using M2 screws

5. Do not add the L/R screen yet
   1. First, insure the ear pads into the adapters to test the ergonomics
6. Test the fit on your head
   1. If the angle or position feels off, unscrew the adapters before rotating them
   2. ❗DO NOT FORCE ROTATION while screwed in - this could damage the headset
7. Adjust as needed until the fit is comfortable and irritation-free
8. Once satisfied, remove the ear pads again and insert the L and R mesh screens into the adapers.
   1. See images fro placement guidance
9. Press the ear pads back into place over the screens
   1. Use the included tool with the ear pads to tuck the pads securely under each tab
