I had a little - issue. A small one really.
But I think Hifiman could pay a litttlllle more attention to the QC. I really love these headphones.
Something wasn’t right on the right earcup. I was hearing a little tiny little tip or tap - very minute for every little beat. Ver faint, but just audible to me. Anyhow, I looked through the drivers with some light. There was something in the magnets and the diaphragm casting an opaque shadow.
I’m the restless kind so I opened up and took the driver assembly out. I took off the fabric too. Lo and behold - a little piece of fine metal dia (prob left off of punching the circuit, as it seems a shiny metal off the inductive coil tracing part). Anyhow, very carefully, I pried this out with a toothpick. It was a bit of risk, no doubt, but I was OCDing.
Now this is def a QC issue and nothing that took place outside of Hifiman’s factory, as the piece was sticking to the diaphragm, and the fabric is then glued onto both sides, and not possible for it to end up where it was, after.
Anyhow - just wanted to share. I guess Hifiman still has some ways to go until these minor and petty issues cease.
DISCLAIMER: Personally, I do not recommend taking off the fabric and diving into the drivers - it’s a bit risky. dia is very thin and fragile. At your own risk, everyone. I had a situation so had to sort it out.
