Chris I share your frustration. The idea that Sony released their very promising range of Cinema headsets so long ago, and those companies who have followed in their footsteps years later, haven't been able to progress the technology without introducing new issues/limitations along the way, is very frustrating.
To Cinera's credit, they have been visibly making an effort to tweak their existing headset. I would hope that ALL of the issues that we have brought up since receiving our headsets would be resolved if/when any future Cinera headset is released.
I prefer the prospect of having to buy another new headset model in order to get what I'm after, rather than the alternative of the company failing (and my losing any prospect of ever getting what I'm after), which is why I have been keen to make myself as useful as possible in communicating feedback.
The 'Personal Cinema Experience' is a very simple concept in principle: Scale-down a big-screen environment to fit within a headset using micro screens and lens optics. In doing so, you create what should be the perfect, fully-controlled viewing conditions for watching video content (short of actually building all this to scale!).
The biggest complication is that while one of the greatest strengths of this technology is the ability to be immersed within a cinematic experience that you can scrutinise down to the minute details on the big screen, the risk of using such a device is that your perception of the video is magnified and intensified to the extent that any flaws or issues with the original source material, or with the lens/screen/image processing of the playback device become intolerably glaring. Therefore, for such a device to succeed, it really needs to display the video material to a high enough level of quality so as to accommodate this heightened level of scrutiny.
It is essentially the whole IPhone 'Retina Screen' concept all over again.
So far, no company has quite managed to fully realise this dream with the technology available, and to a realistic price point...
