The HTC Vive Flow is a compact, lightweight virtual reality head-mounted display developed by HTC, announced on October 14, 2021, and released on November 2, 2021 at a price of $499. Designed as a wellness and entertainment-focused VR device rather than a gaming headset, the Vive Flow introduced a radically different form factor for VR—weighing just 189 grams (several times lighter than traditional VR headsets) with pancake optics enabling a visor-like glasses design. Rather than bundled controllers, the Flow uses a paired smartphone as its primary input device. Powered by the Qualcomm Snapdragon XR1 processor with 3.2K resolution displays, adjustable diopters (eliminating the need for glasses), and active cooling, the Vive Flow targeted meditation, casual entertainment, and media consumption rather than gaming, representing HTC's exploration of VR as a lifestyle device.
