Xreal's X by Xreal (XBX) enters the market at $299, undercutting competitors while delivering the lightest smart display glasses available at 62 grams. The See Ya micro-OLED panels mark the industry's first native 10-bit displays in this category, paired with 3840 Hz PWM dimming across both 60 Hz and 120 Hz refresh rates — a comfort advantage over rivals that halve dimming frequency at higher refresh rates. Peak brightness hits 1600 nits across a 50-degree field of view, with 145% sRGB coverage and real-time SDR-to-HDR conversion that the reviewer found transformative on a Steam Deck.

The standout feature is smooth follow spatial tracking, unprecedented in sub-$400 glasses. However, the tracking operates only in 0DoF mode when 10-bit HDR is active; users must choose between color depth and display stability. The modular frame system uses toolless magnetic attachment and includes 3D-printing templates via Maker World, plus three nose pad sizes and spring hinges with 20-degree flex for broad fit accommodation.

Audio remains the weak point: dual 9x20 mm drivers lack volume for public environments, necessitating earbuds. The on-screen menu, accessed via a button on the right temple, is simplified compared to Xreal's premium models. Despite the tracking-color trade-off and quiet speakers, the XBX delivers a feature set — native 10-bit, spatial tracking, modular frames, class-leading weight — that redefines what $300 buys in wearable displays.
