There was a wild period in early transistor electronics where DC power adapters sometimes used 1/8" phone jacks - before the barrel-style DC plugs became common. Having 9V DC in a form that could be plugged into a microphone input always seemed like a pretty insane choice.

- namibj 1y agoI'd like to mention my USB-stick-shaped audio recorder/player who's headphone jack (only uses built-in mic in any case, though iirc the headphone button skips to the next file) functions as the computer and charging connector. The device was shipped with a cable (USB-A male) <> (TRRS 3.5mm aka 1/8") for this usage. It reports as mass storage.
