Brilliant Labs Halo Black

Halo is designed to fit most people, but not all. The device weighs just over than 40g and, at estimated normal use, can achieve all-day battery life. The device contains a color display, low-power optical sensor for AI inference, dual mics with audio activity detection, a low-power AI processor, and dual bone conduction speakers. Halo is totally open source, design files and code are on Github.
Halo has been designed for an IPD (inter-pupillary distance) range of 58-72mm. This covers most, but not all, people and we suggest using the Eye Measure app to gauge whether Halo is suitable for you.
