What this adapter does

This USB-C to 3.5 mm adapter lets you plug standard headphones into a Type-C phone or tablet that lacks a built-in jack. A second Type-C female branch on the cable carries power so the device can charge while you listen. It is aimed at owners of newer handsets that have removed the analogue socket.

The spec that decides fit

The connector is a USB Type-C male plug on one end and a 3.5 mm female socket on the other, with an extra Type-C female port for charging. The adapter only works when the host device’s USB-C port supports audio output; the supplier notes that several popular models do not support this function.

Install notes and common issues

Connection is plug-and-play with no drivers required, but you must verify that your specific phone or tablet routes analogue audio through its USB-C port before buying. The most frequent problem is purchasing the cable for a handset that lacks audio-over-USB-C support, which results in no sound despite a correct physical fit.

Questions about this item

How does the CDLA chip affect sound quality when I plug my 3.5 mm headphones into a USB-C phone?

The CDLA chip handles the digital-to-analogue conversion inside the adapter so the phone only sends a digital stream. This keeps the audio path free from the phone’s own analogue circuitry and lets the headphones receive a clean 3.5 mm signal.

What does the USB 3.1 label on this adapter actually limit in daily use?

The USB 3.1 marking refers to the data-lane capability of the Type-C plug; the adapter itself only uses the audio and charging lanes, so the 3.1 rating does not impose any extra speed or power limit on headphone playback or pass-through charging.

Will the extra Type-C female branch on this cable fit inside a slim phone case while charging and listening?

The adapter adds roughly 11 mm of depth beyond the phone’s port, so cases with a straight cut-out around the USB-C opening usually accommodate it, while tight wrap-around cases may press against the branch connector.
