Interesting...but i am always very suspicious about these remakes.
what i miss on the site is any technical info (test or measurement results, specs) to show it is actually identical.
In general: once you order enough of whatever you want reproduced in the Far East, they make it for you, but never the same, it looks the same...:), google on the fake B&O A8 earplugs...
i am sure if you bring your HF2000 to Chinatown Bangkok they can fix it for you (and glue in a replace,ent coil with the correct diameter),
i have done so with Beolit speakers, ending up sometimes with a 4 ohm or a 8 ohm version :)
not saying that this is such a product, but that is why i am always suspicious.
i guess someone with a broken HF2000 can test and compare...
but ok: there is lots of repro electronic parts around these days but it is better than nothing.
Hope we can read some test results here one day :)
