USB-C Audio Adapter with Key Chain

This compact adapter adds a 3.5 mm headphone jack to phones that only have a USB-C port. It also passes charging current through the same connector so you can listen while the battery tops up. A built-in key chain keeps the dongle attached to a bag or keys. The integrated decoder chip handles digital-to-analogue conversion without extra drivers.

Phone Compatibility Decides Fit

The adapter only works on handsets that combine charging and audio on a single USB-C socket. Phones with a built-in 3.5 mm jack will not recognise the device. Supported models include the Mate 10, Mate 10 Pro, P20 series, Moto Z, Moto Z Force, Letv Le 2, Le 2 Pro, Mi Max 3, Smartisan Nut Pro 2 and Nubia Z17.

2-in-1 Charging and Listening Headroom

The single USB-C plug carries both power and analogue audio, so one port serves two needs at once. It handles stereo playback and headset microphone calls without a separate power brick. The design does not support phones that keep audio on a dedicated 3.5 mm jack or that use a different USB-C pin-out.

Questions about this item

Does the adapter let me charge my phone and use 3.5 mm headphones at the same time?

Yes, the 2-in-1 design provides a USB-C charging port and a 3.5 mm audio jack so you can power the device while listening.

What limits the audio quality — the USB-C port or the adapter itself?

The built-in decoder chip handles the digital-to-analogue conversion, so sound quality depends on the adapter rather than the phone's USB-C implementation.

How much space does the key-chain loop add when I plug it into a tightly spaced port?

The compact body with integrated key-ring loop is designed to sit flush against the phone, adding only a few millimetres beyond the USB-C socket.
