Thank you! This helped me open my pair of headphones, and I was able to fix an intermittent connection to the headphone jack (by reheating the pads).

I should add that the diffuser for the LED should be pulled off by user before trying to lift up the board, as it will not come off out of it's hole by itself and it does block the board from being lifted.
