The Qwen S1 specs have a heads-up waveguide display etched into the lenses, and serve as a rival to Meta's Ray-Ban Display model (minus the gesture control). My first impression of these AR glasses was that they were light and comfortable to wear -- I wouldn't have known that they were smart glasses by their weight alone. At the end of each arm are swappable batteries, which snap off easily so you can keep the glasses running for longer when you're on the go.
