Bluetooth mode is a standard spoken prompt built into countless Bluetooth speakers, headphones and portable players, spoken in a flat synthetic voice when the device switches to pairing. DankPods, whose channel centres on repairing and modding iPods and other older Apple products, featured the sound in his videos, where its deadpan delivery became a recognisable in-joke for viewers. From there it spread to soundboards and short-form edits, where creators reuse it as shorthand for retro tech, wireless connections and nostalgic gadgets.
