With its Rift model, Oculus set itself as a big player in VR. Now the company is slowly bowing out of the dedicated, tethered VR headset with its latest Quest 2 designed to primarily be a standalone headset.
In case you do not know, tethered headset means that the headset itself is connected to your PC and is using its power to drive your VR experience.
Now technical specifications of Quest 2 are pretty OK and it can drive stuff pretty decently and if you want you can purchase the dedicated cable to connect it to your PC for the full experience of games requiring more capable hardware.
Oculus Quest 2 is the cheapest headset on this list and with its stable performance, is highly recommended.
Although the headset itself is nothing revolutionary or special its controllers are. They can track individual finger movements, making games (that take advantage of them) much more immersive than the standard trigger grips on other controllers.
The Index's higher refresh rate makes for smoother action, as well, which is another nice bonus. If you already have an HTC Vive or Vive Cosmos Elite, and their base stations (not the regular Cosmos), you can buy only the controllers.
The PlayStation VR is compelling thanks to Sony backing its development, plus the PlayStation 4's affordability and availability compared with gaming PCs. All you need is the headset, a PlayStation 4, and a PlayStation Camera (now included with most PlayStation VR bundles).
Not really the best of the bunch but still one of the top ones for console gaming. Sony is working on a new PlayStation VR system for the PlayStation 5, with redesigned controllers. The new headset hasn't been revealed yet, but the company has released a preview of the new controllers.
HP headset is one which you get if you want the best image quality in VR headset, sadly controllers did not follow the same quality of headset itself. But this is still a pretty decent headset overall and worth the purchase.
HTC's Vive Cosmos is the upgraded version of the Vive. It features a higher resolution and replaces the external base stations with outward-facing cameras for motion tracking. It's a comprehensive package for whole-room VR.
HTC recently released the Vive Pro 2, a high-end VR headset targeting both enterprise users and consumers. This new headset features a 2,448-by-2,448 resolution display for each eye, making it the highest-resolution headset currently available. It's also more expensive than the Cosmos Elite.
Sadly one thing that is bringing this headset down is the price. “A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device”.To easily fix the problem, you can try to disconnect the device and click on Reset and if you click on Close, the port will not work until you unplug it and then restart your computer. On the other hand, if disconnecting the device did not resolve the problem, you can try running the Hardware & USB troubleshooter or use a USB hub. You can also try to reinstall, uninstall or roll back the USB drivers or run the OEM diagnostics. For more information, refer to each one of the potential fixes provided below.
