Thanks to all of you for the troubleshooting 💕 When I tested the 2 Susvaras there was no doubt in my mind that Hifiman made a silent revision somewhere between 2020 and now (they are known for doing that). Unfortunately, I completely disregarded the other thing Hifiman are known for, inadequate QC. So yeah, there are indeed flakes of different size and shapes inside the drivers. I guess they peeled off the magnets and got stuck to the diaphragms. But here comes the twist - It’s the 2022 unit that was bought directly from Hifiman’s website. My used 2020 unit from the EU dealer has none of these flakes. I don’t know what to make out of this. Is there a new “bad batch” of Susvaras being sold by Hifiman, or is it just this one unit that somehow slipped through Hifiman’s otherwise immaculate QC? And what’s the idea behind painting the magnets anyway? Does neodymium oxidize? Does Audeze paint their magnets? Why is it always Hifiman who has to screw thing up? Sorry for the rant there 😓 Imagine buying a $6000 headphone and finding out it has a manufacturing defect. Going through the RMA process is not going to be fun. --- _[View the full topic](https://forum.headphones.com/t/hifiman-susvara-over-ear-planar-headphone-official-thread/2293)._
