I believe I read two or three reviews as well as comments mentioning how bad the new HE-560 felt compared the build of an Audeze or Beyerdynamic at the same price range, on top of all the QC issues reported in the headphone thread on the forum.
I'm probably still gonna buy it, but certainly not because I'm confident about the build. They seem to have a nice customer service in the other hand.
I do agree that China is producing great quality though, it's just that they're producing so much for so many at very different price ranges that they're filling the full spectrum, from very bad to very good.
