Brilliant Labs Halo AI Glasses vs Even Realities G2

These two approach the same promise — useful information floating inside an ordinary-looking pair of glasses — from opposite directions. The Even Realities G2 is a finished consumer product: a binocular green display projected through waveguides into a 36-gram titanium-and-magnesium frame, built to be worn all day and forgotten. The Brilliant Labs Halo is an open platform in the same weight class: a single full-color monocular microOLED module in a 40-gram frame, aimed at people who want to program their glasses rather than just wear them. Its hardware and software are open source, and its Vibe Mode turns spoken descriptions into small on-glasses apps.

Daily-wear practicality leans clearly one way. The G2 carries an IP65 rating against dust and rain, runs about two days between charges — 48 hours against the Halo's claimed 14 — and its wireless charging case holds seven more full charges. It also covers prescriptions from -12 to +12 diopters with custom lenses. The Halo answers differently: its display optic adjusts from +2 to -6 diopters on its own, and a maker-named lens partner handles full prescriptions.

The G2 deliberately has no camera at all: its assistant works from voice and text, which keeps the glasses welcome in meetings and places where camera eyewear raises eyebrows. The Halo takes the opposite bet with a small 640x480 global-shutter camera that feeds its Noa assistant — a computer-vision sensor rather than a photography camera, and the reason the Halo can answer questions about what is in front of you while the G2 cannot. The Halo also runs a small vision-language model on the frame itself, so some of that understanding happens without leaving the glasses.

Audio and display finish the split. The G2 ships no speakers — you bring your own earbuds — while the Halo plays through bone conduction. The G2's binocular display renders only in green; the Halo's is full color yet monocular, and Brilliant Labs has not published its resolution or field of view. Pick the G2 to wear a discreet, weather-sealed heads-up display every day; pick the Halo to tinker with an open, camera-equipped assistant that costs noticeably less.
