Defendwe USB-C to 3.5 mm Headphone Aux Adapter with Charging Port

USB-C audio adapter with charging pass-through

This USB-C to 3.5 mm adapter lets you plug wired headphones into devices that lack a headphone jack. A second USB-C female port on the branch cable provides charging pass-through so the battery can be topped up while listening. The compact dongle is plug-and-play and requires no driver installation. It is intended for smartphones and tablets with a USB-C port that supports audio output.

Suits users who want wired audio

Ideal for owners of USB-C phones or tablets without a 3.5 mm socket who wish to keep using existing analogue headphones. The integrated charging branch means you do not lose the only port while listening. Buyers whose device does not support audio over USB-C should look at something else, as the adapter relies on the host to output analogue signals. It also does not work with devices that require a proprietary DAC or active cable.

CDLA USB 3.1 specification for digital audio

The adapter follows the CDLA USB 3.1 standard, which defines how digital audio is transmitted over USB-C to an integrated DAC. This specification determines whether the host device can send audio through the port without an external driver. If your phone or tablet implements CDLA USB 3.1 audio output, the adapter will function; if it uses a different or proprietary protocol, it will not.
