The Microsoft Store is starting to flesh itself out with mixed reality headsets in preparation for Microsoft's push into mixed reality experiences, starting with the Fall Creators Update in a couple weeks. Two of the newest entries include Samsung's Odyssey, a premium HMD with OLED panels based on the same AMOLED technology it uses in its smartphones, and Acer's model.

Like the rest of the current crop based on Microsoft's reference design (save for the Odyssey), Acer's headset uses LCD panels, with a 1440x1440 resolution per eye. It costs $399, making it the least expensive mixed reality headset available alongside Lenovo's Explorer.
