How is the xm5 building quality compared to his predecessors?

Hello, I'm an owner of XM3 and i am considering changing them for the xm5. However I have a little question is the build quality better? because my headphones broke around the sliders and i replaced them, however now I have this creaking issue and the headphones are hard to readjust to my shape of head.

Did Sony made an improvement on their new headphones?
