Oculus Quest 2

Oculus Quest 2 is a virtual reality (VR) headset created by Oculus, a brand of Facebook. It is the successor to the Oculus Quest. It was announced at Facebook Connect 7 and shipped on October 13, 2020. 
As with its predecessor, the Quest 2 is capable of running as both a standalone headset with an internal, Android-based operating system, and with Oculus-compatible VR software running on a desktop computer when connected over USB or Wi-Fi. It is a refresh of the original Oculus Quest with a similar design, but with a lighter weight, updated internal specifications, a display with a higher refresh rate and per-eye resolution, and updated Oculus Touch controllers.
The Quest 2 received mostly positive reviews as an incremental update to the Quest, but some of its changes faced criticism, including its strap, reduced interpupillary distance (IPD) options, and a new requirement for users to log in with a Facebook account to use the headset and Oculus services.
Hardware.
Its design is similar to the original Oculus Quest, but replacing the black, cloth-covered exterior with white-colored plastic and a black face pad. It is lighter than the first-generation Quest, at 503 grams (17.7 ounces) in comparison to 571 grams (20.1 ounces). The strap was changed to a fabric-based version (rather than the elastic-based strap of the Quest), while the power button was relocated to the side of the headset, instead of the original's more forward facing one.
The Quest 2 utilizes the Qualcomm Snapdragon XR2 system-on-chip (which is part of a Snapdragon product line designed primarily for VR and augmented reality devices), with 6 GB of RAM — an increase of 2 GB over the first-generation model. 
Its display is a singular fast-switch LCD panel with a 1832×1920 per eye resolution, which can run at a refresh rate of up to 120 Hz (an increase from 1440×1600 per-eye at 72 Hz). Initially, only 90 Hz support was available, as an experimental feature for the home area at launch (with 72 Hz as the default refresh rate), with support for 90 Hz within games added via a software update in November 2020. On April 23, 2021, a new software update (v28) introduced optional experimental support for 120 Hz in games. The headset includes physical interpupillary distance (IPD) adjustment at 58 mm, 63 mm and 68 mm, adjusted by physically moving the lenses into each position. This is also combined with software adjustment.
The included Oculus Touch controllers are slightly bigger, influenced by the original Oculus Rift's controllers. Their battery life has also been increased four-fold over the controllers included with the first-generation Quest.
Games.
Unlike the original Oculus Quest, the Oculus Quest 2 is not backwards compatible with Oculus Go apps and games. It otherwise supports all games and software that are supported on the first-generation model, and existing titles can be updated to support higher graphical fidelity on Quest 2.
Accessories.
Oculus presented an "Elite Strap" accessory, which contains a ring-like pad for the back of the head and a tightness dial, along with a variant with a battery pack built into the strap. Oculus is also promoting Logitech headphones "certified" for Quest 2 (including the G333 VR, the company's first in-ear headphones model), which have shortened cords designed for use with VR headsets.
In addition, Oculus partnered with Logitech to support their K830 keyboard as part of the "Infinite Office" feature, allowing the keyboard to be detected and displayed within a virtual reality environment.
Release.
Quest 2 was officially unveiled on September 16, 2020 during Facebook Connect 7. The 64 GB model was priced at US$299, a $100 decrease over the original Quest model. The 128 GB model of the first-generation Quest was replaced by a 256 GB model at US$399.
Reception.
"The Verge" was positive in a pre-release review, noting that while it lacked standout features, it did have "worthwhile" improvements such as reduced weight, a screen with a better visual appearance and refresh rate than the original Quest, and a re-located USB port. The new strap was panned for having "less support and a slightly clumsier tightening mechanism" (partly rectified by the Elite Strap accessory sold separately), and the new IPD mechanism was considered "annoying" and not as inclusive as that of the first-generation model. In conclusion, it was argued that while it was not a "must-upgrade" for existing owners, the Quest 2 had "the best overall balance of hardware, features, and price."
"Ars Technica" was less positive, noting that its internal speakers were "noticeably crisper and louder", but panning the new cloth strap in comparison to the original Quest's elastic straps (and arguing that it alone was responsible for the claimed reduction in weight), the limited IPD options, worse battery life, and the controllers having less grip and reduced accuracy on more intensive games. The switch from OLED to LCD was shown to produce "crisper" images but more "washed out" color.
The Quest 2 faced criticism over the mandate that Facebook accounts be used on it and all future Oculus products, It was reported that some users were unable to use the headset due to their Facebook account being suspended. Some described that linking their deactivated Facebook account to the device rendered the headset a "paperweight".
