Like on the Sonys, these ear cushions clip to their cup housing. With a little spudger persuasion, they are free—effective, if not as elegant as the AirPods.

Unlike the Sonys and the AirPods, the cloth liner over each speaker grille doesn't come up with the ear cushion. The L and R marked liners are slightly glued down, making them annoying to peel off without ripping.

Under the liner, Torx security screws guard the entrance to each ear cup.

Both cups hold a mess of wires—but the right one, home to the main circuit board, is truly tangled.

On that circuit board lives a Qualcomm CSRA68105 Bluetooth audio SoC. Here are some full-res images of that board, if you want to do more sleuthing: front, back.
