Virtual Reality or VR for short has come a long way from its infant stage and as 2022 is in half period we are looking at the VR market and reflecting on what has changed in one year. For starters, games have increased in quality and quantity while the hardware price has decreased making the whole VR experience a little closer to a wider audience.
Many companies have tried to get on the VR bandwagon but also many have failed. What remained are staples in VR hardware from large companies that have started with VR early and kept improving their headsets.
So with great pleasure, we are presenting the remaining best 3 virtual headsets so far of 2022 brought to you from Sony, Valve, and Meta.
SONY PLAYSTATION VR
If you want VR on consoles then there is really one option, and that is SONY VR. Premium Virtual Reality solution from SONY, sadly you can do this only on Playstation 4 and Playstation 5. Sony managed to pull off great quality hardware and packed with its exclusives on playstore at a very affordable price that is still cheaper than other products.
While waiting for the Sony PlayStation VR2 headset this one is still a great option and quality is still among the top of the game. From the time of its release until today, many AAA titles have been released for it as exclusives that you can not play any other way and some of them are really worth it.
VALVE Index
Altho there are headsets like HTC Vive Cosmos Elite that have some features that place it as a better solution than Valve Index, Index is still an overall better VR headset as a whole product but its price is something that is keeping it still way out of reach of your standard user. The price, however, is really an illusion since it applies only when buying the system first time, you see Valve has created this headset as a modular design system making it upgradable meaning that you can, for example, buy newer controllers only and they will work perfectly with rest of hardware.
The modular design will save you money when you want to upgrade your VR system but as said entry price is steep. Besides its somewhat higher price than competitors, it is also notable that Index is a positional tracking VR set which means that it relies on a base station in order to locate the user. This means that once set, it is not so easy to change its location of use.
However, its quality and steam use are unmatched, high-quality games and compatibility that no other headset with steam will even pull off probably make Index one of the 3 best headsets out there. Half-life Alyx, arguably and currently one of the best VR games ever made so far was specifically designed for Valve Index and other games are behaving also incredibly nice with this headset, so if you want a great powerhouse for PC VR gaming, you will no go wrong in purchasing Valve Index.
META QUEST 2
Cheapest of the three and coming in various iterations, Meta has established itself from the beginning as a leading player in VR technology with its oculus line of products. Quest 2 is the next product in their line and it comes with 128GB and 256GB versions.
Meta has removed the need for the Facebook account for its VR systems and now you can use them without the need to send any kind of data to meta. Priced fairly for its entry 128 models this standalone VR set improves in any way possible from its previous iteration and sets the bar for what will come in VR's future.
Offering both wired and wi-fi connection with its standalone battery Quest 2 also is packed with a large library of games and it is user friendly as your typical game console but still allows some under-the-hood tinkering if you wish so.
Also, Meta's Vr solution since it uses inside-out tracking makes it incredibly easy to just pick it up and carry it with you wherever you go.

Sadly finding this option on your TV will be different from manufacturer to manufacturer and even from model to model of the same manufacturer so we can not cover all models but in most cases option is located under picture settings or advanced options. Sometimes you will face even different overscan settings instead of classic ft to screen options, in this case, experiment with the setting until you find one which will work.
