Vivo is a smartphone brand whose handsets play a short branded chime when they switch on and a matching tone when they switch off. Because the tones are so short and instantly recognisable to Vivo owners, they have circulated online as a compact soundboard clip for tech creators. Editors reuse them to suggest a phone booting up, restarting, or ending a session without filming an actual device. The appeal is practical rather than musical: the sounds carry instant device context in under a second, so they still appear in unboxings, reviews, and phone-themed edits.
