Interesting... have you photo of this hole eventually?Hifiman QC ain't great bit their CS is. My first set developed a hole in the driver within a week of ownership. Hifiman just replaced the entire thing no questions asked
Here are some pics. The mesh on both sides of the driver was intact so it wasn't a puncture unless it was something microscopic and my new set have had 0 issues being used in the exact same environment for now several months (first set popped in under a week)Interesting... have you photo of this hole eventually?

Yah. My guess was that there was a tiny hole/imperfection from manufacturing (that I couldnt see when I first got it) that acted like a stress concentrator and caused the tear. Ultimately though, as annoying as it was for the like 6 days it took to get fixed, it wasnt that big of a dealThis puncture looks like excessive tension on the membrane surface that torn it apart in that spot eventually, but good to know that the manufacturer handled that issue.
Thank you, I see very small white points without gold coating (like holes) on booth my diaphragms when looked against strong light, hope that is normal. So far my set works OK after a month of use.Here are some pics.

Just to be clear. They sorted this out for me with 0 issues and the dealer I bought them from was super helpful as well (said usually they would just swap it for a good set but they didn't have any inventory which is why I went through hifiman directly).

Take a pic and let support know. See what they say. Better to have written documentation in case something happens down the road. That’s what I would do.Thank you, I see very small white points without gold coating (like holes) on booth my diaphragms when looked against strong light, hope that is normal.

I'll try to take a pic, but this spots are very small. I'll post back.Take a pic and let support know. See what they say. Better to have written documentation in case something happens down the road. That’s what I would do.
My good set has a couple of those. I think its normal. Unless you are nearing the end of your warranty or something I just wouldn't worry about it tbhI'll try to take a pic, but this spots are very small. I'll post back.
Thank you for checking on your set and confirming that is not only on my unit! My set was QC/factory sealed 2.12.2021 according to labels on the box, it is new.My good set has a couple of those.
