HTC Americas General Manager Dan O'Brien revealed the Vive Cosmos at CES, but didn't announce any details about availability or price. He promised more information in the near future.

A trademark filing for the Vive Cosmos popped up last year, and fans have been speculating that it would be a standalone headset -- something to compete with the Oculus Quest, for instance. The Cosmos doesn't appear to be a standalone device, though potential smartphone connectivity makes it more mobile than previous Vives.

HTC launched its standalone headset, the Vive Focus, in the United States this past November for $600, though it was marketed toward businesses rather than everyday consumers. The company's main headset line, the Vive and Vive Pro, are tethered headsets that require a PC connection to function. However, at CES 2018, HTC revealed the Wireless Adapter, essentially cutting the cord for Vive and Vive Pro users -- just with an extra, antler-like accessory.
