A wire to the puck, not fully wireless

A cable connects the glasses to the compute puck, which cuts latency versus wireless. Meta's Orion prototype went wireless; Aura goes wired. Early hands-on impressions called the glasses very light thanks to the tethered design, with sharp displays and a compact build.

Xreal's Project Aura keeps the glasses light by moving the heavy stuff, battery, processor, all of it, into a separate puck you carry in your pocket, connected by a wire. Apple's Vision Pro does the same thing with its external battery pack, so Xreal's in familiar company. The tradeoff is: lighter on your face, but you've got a cable running to something in your pocket.
