Dual-Function USB-C Adapter

This adapter connects 3.5 mm headphones to USB-C devices that lack a headphone jack while also providing a charging port. It works with a simple plug-and-play connection and requires no driver installation. The metal construction and coated plug are designed for durability and a smooth feel. It lets you listen to music and charge the device at the same time.

Build Integration

The cable adds a 3.5 mm audio jack and a USB-C charging port to a single USB-C socket on the host device. It frees the user from choosing between wired audio and battery charging during use. The compact, lightweight design makes it easy to carry alongside a phone or tablet. Inline controls allow pausing playback and answering calls, though volume adjustment is not supported.

Sustained Operation

The USB-C interface supports a higher current level to maintain charging speed while audio is playing. The combined metal and plastic build is intended to withstand repeated insertion and daily transport. The adapter draws power from the host device to operate the audio circuitry and pass-through charging. It is not suited for users who need onboard volume control or a separate DAC function.
