The ear cushions can be pried off using a plastic card. First, remove two screws on the bezel. If you lift the fabric, you will find two more screws hidden underneath at the top and bottom. In the photo, the fabric has been generously detached from the adhesive. It is also possible to reach the screws with careful handling.
You must release the screws with a Torx Security 6 (TR6) screwdriver. There is a security pin in the hole, which makes releasing them with a standard Torx driver difficult or impossible.
Use the plastic card to release the detached part from the outer edge.

The small screws can be released using a Phillips #000 or #0 screwdriver.

Open it in the same way as the other side.
The arrows mark (clockwise) the power/Bluetooth button, the voice assistant button, and the USB-C port.
