When considering augmented reality (AR) glasses, the Asus AirVision M1 stands out, priced at a steep $699. Despite its potential as a companion for Windows-based devices, especially with Asus' ROG Ally gaming handheld series, the AirVision M1 falls short in several key areas.

Firstly, the build quality of the glasses is underwhelming. Made entirely of plastic, the AirVision M1 lacks the premium feel of many Asus products. The plastics used are of subpar quality, with a thin, hollow feel and an easily scratched finish. This is especially disappointing considering the Xreal One, a similar device from Asus, offers a significantly higher quality build with a titanium lens frame.

Despite the adjustable interpupillary distance (IPD), the AirVision M1 struggles with focus issues. This becomes particularly evident when engaging in productivity tasks or gaming, where text and images remain blurry, leading to eye fatigue. While the glasses can simulate a 100-inch virtual display, the compromised focus detracts from the immersive experience.

Additionally, the refresh rate of 72 Hz is dependent on the AirVision app for Windows, which is not supported on other operating systems. This limitation is particularly noticeable when compared to competitors that offer native 120 Hz support. The sound quality from the built-in speakers is also lackluster, with a flat sound and muffled audio in games.

In conclusion, the Asus AirVision M1 AR glasses are a flawed product at its current price point. With a more competitive price, better build quality, and improved focus, it could be a more appealing option for AR enthusiasts and gamers.
