The tone comes from Google Pixel phones, where it plays by default when the device is plugged in and begins charging on Android. Because Pixel devices are widely used by reviewers and creators, the sound became instantly recognisable outside the phone itself, often appearing in unboxings, setup guides, and short-form videos to show a device powering up. Its clean, minimal design fits Google's Android sound language, which is why editors still reach for it when they need a believable, modern phone sound rather than a generic ding.
