We custom designed a simple solution for a serious problem, the broken headband hinge swivel area on the Sony WH-1000XM5 Noise Canceling Headphones. There's a commonly known weak area in this particular model which can cause the headphones to be unwearable if not repaired as quickly as possible. We firmly believe in the Right To Repair. So many big tech companies want to keep selling the newest models with complete disregard for quality and design, it's quite sickening. The average consumer is left "holding the bag" so to speak once the warranty expires, or the manufacturer flat out denies any warranty claim. We don't think that's fair to you. You should have options, that's our goal, to create them for you. Why should you dish out another $350-$450 on a new pair of headphones because Sony had failed you? For about 10% of that price you can repair your own headphones in 10 minutes or less with our repair kit. Whether your headphones are already broken in the area, or you want to reenforce this weak spot to prevent them from breaking, our custom parts kit is a simple and cost effective solution. This 8 pc parts kit includes the parts and tools to get your Sony XM5's back where they belong, on your head. The part are a bit rough to the touch. These parts are not your typical lightweight thin plastic injection molded parts. Our parts are rugged, thick, heavyweight and durable. It's immediately noticeable when you see and hold them. NOTE: If any adhesive or tape has been used to attempt a repair make sure it's completely cleaned off or these parts may not fit correctly.
