Plastic Hinge Swivel + XM4 U Shaped Metal Hinge Lock Grove Replacement for Sony WH-1000XM4 WH1000XM4 Headphone (Right)

The process for fixing this is a bit tedious. Please be careful when taking off the gasket rubber ring. Also I think that the screw driver should be a little bigger. When screwing off the motherboard you might need to press hard and trun the screw at the same. Other then that everything is good.

Well, this really is a crppy piece of kit! As multiple others have noted, the screwdriver is possibly the wrong size. It has stripped one of the (very tiny) screws, although this may also be due to Sony using poor quality, overly tight screw. Nevertheless, I painstakingly followed all the steps in the video, put it all back together. Everything looked fine until I tried to charge it. The light keeps flashing red (supposedly indicating overheating) and the headphones no longer work.

Das Schnier war am Kopfhörer meines Sohnes gebrochen. Mit der Anleitung war es leicht zu tauschen und funktioniert seither einwandfrei.

Replaced broken original part with this during 5 min.

This hinge seems and works pretty much like the original one. Keep in mind that on the provided tools (screwdriver and Pry Tool) the Philips screwdriver isn't good enough and on some screws it should be a little bit challenging. I do recommend an extra set of mini screwdrivers just in case, the Pry tool provided is quite good though.
