I have WH-1000 headphones. They are about 6 weeks old. However I can not switch them off and they cycle through the following messages 'power on' , 'Bluetooth pairing', 'power off', 'power on', 'Bluetooth pairing', 'power off' etc. It does this randomly changing the sequence, with the occasional 'battery at 70%'.
Hey marsh167, try to reset them: https://helpguide.sony.net/mdr/wh1000xm4/v1/en/contents/TP0002752743.html
