The chime comes from Meta's Quest line of standalone virtual reality headsets, formerly sold under the Oculus name before Meta rebranded the hardware. It plays during the hardware startup sequence, before the user reaches the home menu and guardian setup. As Quest headsets became widely used for gaming, streaming and VRChat, recordings of the boot sound spread to YouTube, TikTok and soundboards. Creators now reuse it as a shorthand for entering VR, starting a game session or switching on any futuristic device in an edit.
