Rayneo Launches Air 4 Smart Glasses with Bang & Olufsen Audio in China
Rayneo formally launched its Air 4 smart glasses in China today, November 3, 2025, offering upgraded audio and display technology over its previous models.
The new glasses feature audio tuned by Bang & Olufsen, paired with a dedicated DSP chip, aiming to deliver “flagship headphone level” sound quality. Rayneo also incorporated HDR10 displays and a Pixelworks custom chipset into the Air 4, promising enhanced image quality and dynamic range, even converting standard dynamic range (SDR) content to HDR using artificial intelligence. The tandem micro-OLED displays are capable of producing 10-bit color.
Eye protection features, comparable to those found in high-end smartphones, include 3840 Hz PWM dimming, while maintaining the 1,200 nits brightness found in the Air 3S Pro. A Pro variant of the Air 4 is also available, adding support for 3D Audio as its sole differentiating feature. The development of more sophisticated AR glasses is a key component in the evolving landscape of augmented reality technology.
The Rayneo Air 4 is priced at CNY 1,599 (approximately $224), with the Pro model costing CNY 1,799 (around $253) in China. While Rayneo has not yet announced a global release date, the company has a history of bringing its products to international markets. You can learn more about Rayneo’s product line on their official website.
Rayneo officials stated they will share information regarding international availability as soon as it becomes available.
Rayneo has formally launched the Air 4 in China. The new smart glasses build upon the 3S Pro and offer a handful of new features. Among all is the improved audio setup that’s tuned by Bang & Olufsen, promising an even more immersive listening experience than the previous models.
There’s a dedicated DSP chip as well, which, paired with the Bang & Olufsen tuning, is claimed to make the AR glasses offer “flagship headphone level” audio. Another notable improvement over the Air 3S Pro is that the new smart glasses have HDR10 displays.
This upgrade, combined with the Pixelworks custom chipset, is said to offer enhanced image quality over the predecessors. There’s a dynamic HDR tech in place, which converts SDR content to HDR with AI. Rayneo further highlights that the tandem micro-OLED displays of the Air 4 can produce 10-bit color for immersive viewing.
The new AR glasses have eye protection features that are similar to those of a “flagship phone,” including 3840 Hz PWM dimming. However, the micro-OLED panels have the same 1,200 nits brightness rating as in the Air 3S Pro (non-Pro curr. $215.20 on Amazon). Rayneo also has a Pro variant, and the only difference appears to be support for 3D Audio.
As for the price, the new Air 4 costs CNY 1,599 in China, about $224, while the Pro model goes for CNY 1,799, around $253. Rayneo didn’t share when the new smart glasses will launch outside China, but the brand is known for bringing most of its products to the global market.
