USB-C to 3.5mm Audio and 60W Charging

This adapter adds a 3.5mm headphone jack and a USB-C power pass-through port to devices that only have a single USB-C connector. It lets you listen to wired audio while the device charges at up to 60 watts. The built-in Conexant CX31993 chip handles 32-bit 384kHz digital-to-analogue conversion for high-fidelity stereo output. An internal capacitor filters ground-loop noise to prevent static during simultaneous charging and playback.

Replaces Missing Headphone Jack on USB-C Devices

It restores wired audio capability on phones, tablets and laptops that have removed the 3.5mm socket. The jump is worth it when you need to use existing wired headphones or an aux cable in a car while keeping the battery topped up. The adapter retains inline remote functions such as volume control, track skipping and call answering. No driver installation is required; it works immediately on supported USB-C hosts.

Suits Users With Wired Headphones and One USB-C Port

Ideal for commuters and drivers who rely on 3.5mm headsets or car aux inputs and cannot sacrifice charging time. The braided cable and aluminium shell resist wear from daily plugging and unplugging. Not suited for devices that lack USB-C audio accessory mode support or for users who need more than one additional USB-C port. Buyers who want more storage or multiple peripheral connections should look at a multi-port hub instead.

Questions about this item

Does the USB-C plug on this adapter fit the port on a Google Pixel 4?

Yes, the adapter lists the Pixel 4 among its supported USB-C devices.

What step do I take to start using the adapter — is any driver or app required?

No driver or app is needed; simply plug the USB-C end into your device and connect your 3.5mm headphones and charging cable.

Which part of the adapter is most likely to wear out first with daily plugging and unplugging?

The anti-oxidation 3.5mm jack and the braided cable are designed for repeated use, so they should last longer than standard connectors.
