Halliday G2
A discreet binocular HUD for live conversation — closed to everyone else's software.
{{name}} — specification and verdict
The G2 puts a small binocular micro-LED image in front of both eyes at 25.2 degrees and up to 1600 nits, rated IP54, with about twelve hours of use. It is sold for live professional conversation: captions, translation and notes appearing in your line of sight, and it deliberately has no camera.
Everything runs in Halliday's own phone application, and the company states plainly that the G2 does not integrate with third-party assistants, agents or external models. That is as closed as this comparison gets — there is no path for anyone else's software, ours included.
A neat answer to one specific problem: reading what the other person just said, in a meeting, without looking down. Not a work-instruction device — no camera means no remote expert and no photo record — and Halliday publishes neither a weight nor a shipping country list, which is worth asking about before ordering.

Company rollout
- Third-party appsHow a third party's application reaches the device: an ordinary Android package, a vendor-only SDK, or not at all.
- Closed platform
- Runs Skillsive appsOur own statement about whether Skillsive training applications run on it today.
- No
- Suitable for trainingOur judgement on whether it survives real deployment: comfort, hygiene, fleet management.
- Suitable for training: Specifications checked against the manufacturer's page on 2026-08-04.
- Kiosk mode / MDMVendor tooling to enrol devices, push an app and lock the headset to it. Practically required above ten devices.
- No
- Business tierAn official business tier, so devices belong to the company rather than to employees’ personal accounts.
- Business tier: Specifications checked against the manufacturer's page on 2026-08-04.
- CertificationsIndustrial certifications stated on the manufacturer's own page. Empty means unconfirmed, never "probably fine".

Platform and performance
- Where it computesWhether the device computes on its own or depends on a phone, PC or belt-worn puck.
- Driven by a phone
- ProcessorThe processor and memory inside. This is what the performance grade above is derived from.
- Processor: Specifications checked against the manufacturer's page on 2026-08-04.
- MemoryRAM on the device. Together with the chipset it sets how complex a scene can be.
- Memory: Specifications checked against the manufacturer's page on 2026-08-04.
- PlatformThe platform an application is built against — and what an MDM has to speak.
- Halliday app (iOS / Android)
- BatteryRuntime as the manufacturer states it. A hot-swappable pack matters more than the figure.
- 720 min
Display and optics
- DisplayHow the image is produced. "No display" is a real answer in this category, not a gap.
- Waveguide
- Eyes coveredOne eye or both. Over a full shift this is a real difference in fatigue.
- Both eyes
- Resolution per eyePixels delivered to each eye. Higher means small text and labels stay readable.
- Resolution per eye: Specifications checked against the manufacturer's page on 2026-08-04.
- Refresh rateImages per second. Higher feels smoother and helps people prone to motion discomfort.
- Refresh rate: Specifications checked against the manufacturer's page on 2026-08-04.
- Field of viewHow much of your view the image covers. Bigger is more immersive, not automatically better for work.
- 25.2°
- Pixel densityPixels per degree of view — the honest way to compare sharpness between a headset and a pair of glasses. Higher is sharper. Only shown where somebody published it; we never compute it ourselves.
- Pixel density: Specifications checked against the manufacturer's page on 2026-08-04.
- BrightnessIn a plant or outdoors, brightness decides legibility more than resolution does.
- 1600 nits
- WeightThe device alone. Anything above roughly 150 g is felt within an hour.
- Weight: Specifications checked against the manufacturer's page on 2026-08-04.
Tracking and input
- TrackingWhether content stays put in the room (6DoF), follows head rotation (3DoF) or is simply fixed.
- None
- Hand trackingWhether bare hands can operate the interface, without a controller or the phone.
- No
Connectivity and audio
