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

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.

Repair was straightforward if a somewhat involved set of steps - check the YouTube video to see of your comfortable doing it yourself. The part fit and the spunger and screwdriver worked perfectly. Much cheaper than buying a new pair of headphones, for sure!

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

I broke the right hinge after 3 years of solid use on the XM4s. Sony quoted $150+tax for it's repair. It's almost half of the price of the new ones. Isn't this madness? For $20, this made my headphones as good as new. It took about 20 minutes to take the headphones apart, replace the hinge, and put everything back together. The video link on the product page is for the left side hinge only. You can YouTube the right side hinge replacement from the same channel. The whole disassembly process looks way scarier than it is, but at the same time you have to be gentle and careful because of the wires. What do I even review about this product? It's cheap. It works exactly like the original. Can't say anything about durability, but based on initial impressions, these feel sturdy enough like the original. Screw all these repair centers and OEMs ripping people off for even the simplest repairs.

Con la guía de un video y paciencia pude hacer la reparación de mis audífonos, llevo más de un año usándolo y no tengo problemas

My headphones were broken for more than a year and I thought to myself there has to be a replacement part. It seems this is a common part to break based on users from the internet. Was glad to find this replacement. The video was perfect and explained how to fix it. It was so easy I did this during my lunch break at work haha. Time will tell if it holds up longer than Sony's OEM part but I am hopeful and this is only 30 bucks to save my $500 headphones so it's no biggie.
