Hello together! My problem is that the headphones usually switch on but then switch off again shortly afterwards. This often happens 2-3 times until the headphones stay on permanently. Do you have any ideas on how to fix this? With a software update or resetting to the factory settings (if this is at all possible with headphones)?
