The original author of Hifiman called Winny in the internet. It is said that his son likes Winnie the Pooh. He started to make electrostatic headphones very early. His early masterpiece was a replica of Orpheus——Jade. But he cannot produce Jade in bunch, I read an interview, He said that Jade with the best sound has slight electric leakage, like a needle, while Jade with very safe sound is not pleasant to hear. His partner, Dr. Bian fan, accidentally discovered that he had made a planar headphone, which was actually a small toy he had made for himself. Dr. Bian Fang thought that since electrostatic headphones could not be put on the market, it would be better to make planar one. Only in this way did the famous he6 come into being. In other words, the development of he6 was an accident.
Although the success of he6 has gained a great reputation, it has not sold a lot because He6 is difficult to drive and heavy to wear. After the market test of He560, they decided to develop their flagship. I believe they want to make their Orpheus through planar headphone beacuse the Electrostatic technology is still immature.
I remember Hifiman He1000v1 was announced as the flagship when it was released. However, it is reported that it has made obvious mistakes in tuning, I haven't actually heard of V1 so I have no idea what mistakes. So hifiman he1000v2 is likely to be a product of public relations crisis. It solves the problem of he1000v1, but deviates from the original path, thus its price collapse seems reasonable. Then hifiman launched the he1000se, which became an headphone that is easy to drive. I think this declared the complete failure of this series because this is not the positioning of the flagship. Although this series failed, it did not stop developing, all costs of Hek series became sunk costs, a friend told me he found arya sounds like he1000v1, if it is true, that means Hifman reborn he1000v1 through Arya.
After the success of He6 and the failure of HE1000, they finally produced a very strong product. I would like to call it a real planar flagship-Susvara. On the other hand, Winny did not give up electrostatic headphone, and finally made Shangri La, but it was extremely expensive.
As for R10D/P? It was completely copied from Sony.
What I wrote is not from speculation. The evidence is hidden in hifiman's product tree.
