nana2711 In my case I need to get a small rigid object and press it into the power button pretty hard at different angles for the button to actually get pressed. It still has a faint click when you press the button but it only works if you press it really hard. Idk what happened I just stopped playing it for a while then when I picked it back up I thought it was broken until I tried pressing the button harder. Maybe it got crushed at one point or it’s dirty underneath, but I haven’t taken it apart yet. Hopefully this is also your issue and the headset isn’t broken.
