Be patient, Herry is quite busy (super busy) with his family business, as well as some other custom commissions he is working on both earbuds and vacuum tube amp wise.
Back in 2018 I listened to what I was told was a
CAX Black Edition (second to the
CAX Red Dragon) and I was not impressed at all. Very bright and not that headphone-like experience that I had read/heard about (maybe the
CAX Red Dragon was more that...). I remember wondering if the
CAX Black Edition I listened to (no idea which version it was) might have been a copy or a knock-off as a
Simphonio (Sunrise Audio) SW-Dragon 2 Plus would have done circles around it at the time.
Then in 2020 I listened to two different
CAX Black Dragon models one with the stock tuning and one with Sennheiser HD800 inspired tuning... personally, I didn't like either one of the tunings too bright and fatiguing for me (but please note I am weirdo with picky hearing) but they were very well tuned and marvelous earbuds nonetheless.
Many people do very much like the
CAX Black Dragon,
CAX Red Dragon (very rare, I have never had the pleasure to listen to one yet

), and the various
Freds (which I generally did like but again too much treble for my tastes).
Recently, the
Cypherus Audio (CAX) Zane Titanium Dragon offered a full-sized headphone experience but was too fatiguing for me plus I was having some serious hearing issues with my right ear before so that might have been a factor as well).
