The Xiaomi Mijia and the Cosmo Vision are both standalone AR headsets, but have some distinct differences that can be seen at first glance. Both offer impressive features that make them stand out from their competitors.

Starting with the Xiaomi Mijia, this headset has yet to be released but is highly anticipated in the tech world. It is said to feature an advanced processor, Bluetooth support, and a larger field of view than many other AR headsets on the market. While we cannot definitively say if these claims are true until its release, it has shown potential in terms of specs and design.

Meanwhile, the Cosmo Vision features a 10 degree field of view and a resolution of 304x256 pixels per inch. The field of view might not be as large as what some people are looking for in an augmented reality headset, but it offers good quality visuals nonetheless – making it ideal for casual users who don’t need extreme realism or detail in their experience. The resolution may not be as sharp as you would find on more expensive models, but it still provides decent clarity which makes it suitable for everyday tasks such as watching movies or playing games.

In terms of comfortability, both headsets seem to hold up well during extended use thanks to their lightweight designs and adjustable straps/headsets fitters. This makes them great options for those who plan to wear their headsets for hours at a time without feeling too much strain or discomfort on their face or neck area. They also have built-in earphones which provide clear sound quality when compared with some other VR sets on the market – making them better suited for longer gaming sessions without causing any kind of fatigue due to poor sound quality (which can happen with some cheaper models).

In conclusion, both headsets offer great features that make them worth considering when searching for an augmented reality device: while they do have slight differences between each other (e.g., field-of-view size), they both share enough similarities that they should satisfy most users’ needs no matter what their specific requirements are – whether someone requires a more compact setup or higher resolution images.. With all things considered I would personally prefer using the Xiaomi Mijia due its higher specs being much better compared to Cosmo Vision although only time will tell when its finally released - however based upon my personal usage so far with Cosmo Vision I believe Xiaomi will set itself apart from many competitors thanks to its impressive hardware specification list once fully realized!
