Summary
SiNGRAY G2 puts Xreal-style birdbath optics in a standalone headset for enterprise, aiming to be a spiritual successor to HoloLens 2.
The headset is being developed by HMS, a Japanese computer vision company that makes and sells AI smart cameras and SLAM modules. It was first teased back in June, and this week is being demoed outside Japan for the first time at Augmented Enterprise Summit (AES) in Dallas.
Like Xreal and Viture glasses, SiNGRAY G2 uses birdbath optics, magnifying 1920×1080 micro-OLED panels over a 47-degree diagonal field of view using a small concave mirror.
Birdbath optics are much lower cost than the waveguides that HoloLens 2 used, but have the tradeoff that their display opacity is inversely related to the lens opacity. Thus, to show virtual objects and interfaces that aren't too translucent, birdbath devices give you a dim view of the real world.

Whereas Xreal and Viture glasses require an external computing device and power, SiNGRAY G2 features a Snapdragon 8 Gen 2 chipset, the phone chip that the XR2 Gen 2 in Quest 3 and Pico 4 Ultra is loosely based on.
Rather than doing tracking on the main chipset, as a Quest or Pico would, SiNGRAY G2 also has a secondary VPU (Visual Processing Unit), Intel's Movidius Myriad X. That's a similar approach to HoloLens 2, which used a Microsoft-developed "Holographic Processing Unit" for tracking.
The combination of the offloaded tracking and optical see-through approach of SiNGRAY G2 means it should offer superior performance to Quest 3, in theory at least, while the newer chip makes it 3-4x more powerful than HoloLens 2.
The headset's 18.2 Wh battery is comparable to other headsets, but is hot-swappable, with a small secondary battery enabling a three minute grace period.

On the software level, SiNGRAY G2 runs a fork of Android, and is compatible with OpenXR content.
The headset will come preloaded with software from frontline.io, which says it provides a "complete, end-to-end system" for industrial AR applications like training, remote support, and guided procedures.
There's no public price announced for SiNGRAY G2, but preorders should open later this year, and mass production is planned for 2026. The device will be available only for enterprise customers – this isn't a consumer headset.
