Halliday launched one of 2025's worst-reviewed smart glasses at CES 2025. The G1's Digi Window display—a 3.6mm micro LED module projecting text millimeters from the eye—was deemed unusable. Critics including Engadget (score 54), Android Police (5/10), and TechRadar panned it. COO Carter Hou admitted "many mistakes," citing inexperience with manufacturing and insufficient QA.

The Halliday G2 addresses core flaws with waveguides in both lenses for better readability, a 12-hour battery, improved audio comparable to Meta, and a charging clip replacing the problematic USB-C port. A touchpad replaces the ring controller. Features focus on basics: notifications, calls, translation, teleprompter, and proactive AI—navigation omitted for focus.

Halliday pivots to business meetings, deploying parallel AI agents to track decisions, prompt commitments, and answer questions in real time. Moody Lenses backing provides financial stability; an early production run is with global beta testers. The G2 retails for $599 with a $10 deposit yielding a $100 discount; G1 owners pay $299. Shipments target September.
