UGREEN USB to 3.5mm Audio Jack USB A Sound Card Adapter /30757
The UGREEN CM477 (item 30757) is an external USB sound card: it plugs into a USB-A port and gives you a 3.5mm TRRS socket for a headset with headphones and microphone. It plays stereo audio up to 24-bit/96kHz and has a 25 cm nylon-braided cable with an aluminium alloy shell.

Headphones and microphone through USB: The 3.5mm TRRS socket carries both sound output and microphone input, so a headset with a single 4-pole 3.5mm plug can be used for calls, games and voice chat on a computer or console that has a free USB-A port.
Up to 24-bit/96kHz: The adapter supports stereo audio up to 24-bit/96kHz.

Aluminium shell and braided cable: The aluminium alloy housing and the 25 cm nylon-braided cable are made for daily plugging and unplugging.
Plug and play: No drivers or apps are needed. Plug it into a USB port and the system recognises it as an audio device.
Who it's for / Works with
Computers and laptops with Windows, macOS or Linux, and PS4 and PS5 consoles, used with 3.5mm headphones, headsets or speakers.
