How to use

Insert the USB Type-C plug into the USB-C port of your source device and connect your headphones or audio cable to the 3.5mm socket of the adapter. Ensure the device is unlocked and any required system audio settings are set to the wired output if applicable. The adapter is intended for plug-and-play operation; no additional drivers are normally required. For devices that require digital-to-analog conversion, verify that the source supports USB-C audio output or use a device with compatible audio routing.

Recommendations

Handle the adapter by the housing when plugging and unplugging to avoid stressing the cable or connectors. Store the adapter in a protective case or pocket to prevent dust and debris from entering the 3.5mm socket. If audio does not work immediately, check the device’s audio output settings and test with another pair of headphones to rule out headset or cable issues.
