This version is billed as a take on a prank phone sound rather than an official clip from a show, film, or game, and its listing gives no documented original source. That open, user-made status is common for meme soundboard clips, which are often remade, distorted, and shared again for a louder reaction. The existing headphones warning fits that style, signalling a clip meant to be played loud for a startle. It survives because the joke is simple and reusable: a phone sound pushed past normal volume, dropped into a new edit whenever a creator wants an instant shocked reaction.
