Add a headphone jack and mic input to a laptop over USB
A UGREEN USB sound card on a short lead that turns one USB port into a stereo headphone output and a microphone input, so a laptop with a dead or missing 3.5mm jack still gets clean analogue audio.
This is the UGREEN US205 / 30724 USB sound card cable adapter: a small external audio interface built onto a short (about 15cm) lead.
One end is a USB-A male plug that goes into a laptop or desktop USB 2.0 port; the other end fans out into two colour-coded 3.5mm female sockets, a green stereo headphone or speaker output and a pink mono microphone input.
It runs on a C-Media audio chipset and is fully USB bus-powered, so there are no batteries and no wall adapter to worry about; the host USB port supplies all the current it needs.
It is class-compliant and plug-and-play, so the operating system picks it up on its own with no drivers to install, and it is recognised on Windows, macOS, Linux and PS4.
The cable form sits more comfortably at the side of a laptop than a rigid dongle, which can strain the port or block a neighbouring socket.
It is the quick fix when a machine has lost its analogue jack, when on-board audio is noisy, or when a presenter needs a separate mic input on a laptop that only has a single combo jack.
It gives stereo out and mono mic in, so it covers everyday playback, presentation and voice work, but it is a consumer-grade sound card, not a multi-channel studio interface.
Why Choose This Product
- Separate mic and headphone jacks: splits one USB port into a stereo audio output and a mono mic input, so a lectern mic and a speaker feed can run at the same time without a TRRS combo splitter.
- No drivers, no power: class-compliant and USB bus-powered, so it is plug-and-play with no batteries, no wall adapter and nothing to install on Windows, macOS, Linux or PS4.
- Rescues a dead jack: restores headphone and mic audio on a laptop whose built-in 3.5mm socket has failed or was never fitted.
- Cable form sits better: the short lead lets the adapter rest beside the laptop rather than sticking rigidly out of the port, which is easier in a tight cable bag or a cramped desk.
- Light and portable: a tiny item that drops into any kit bag as a cheap backup audio path for on-site work.
How Can You Use This
- Give a presenter a mic input: add a proper microphone socket to a laptop that only has a single combo jack, for announcers and speakers at small functions.
- Feed a lectern or projector speaker: route audio out to a powered speaker from a notebook that has lost its analogue output.
- Add an audio path for streaming or podcasting: use it as a clean second interface for a headset and mic during training sessions, streams or recordings.
- Back up a sound-desk laptop: keep it in the bag as a fast swap when a laptop's built-in audio output fails on the day.
- Run a desktop headset: plug a wired headset's separate mic and headphone plugs into the two sockets for calls and monitoring.
