USB C to Aux Audio Dongle Cable Cord I tried to connect headphones with only a Type-C audio terminal to a docking station using this cable, but it was not recognized. Upon investigation, I found that these types of products are designed to only support the signal direction when the headphone side has a headphone jack, so it became unnecessary for me. Since I am not using it for its intended purpose, I cannot guarantee its operation, but it is in a new, opened-only condition, purchased on Amazon for about 1600 yen.
