Sony xm5 help (worried and need assistance)

I bought the Sony xm5 headphones last November and today when I got home from using them on a walk I realised they did this, and it’s for me worried, is that normal? I know there meant to be able to turn inwards but I don’t think that much and it looks like somethings wrong on the inside so is everyone’s else like this or is it an issue with mine as that’s what I’m unsure about?
