The UGREEN CM477 is specifically designed to solve the problem of a faulty sound card or a broken 3.5mm port on laptop and desktop systems. By adding a TRRS 3.5mm port, which functions as a built-in audio input and output via the available USB port, it instantly restores your system's functionality. This plug-and-play device allows you to avoid the high cost of repairing or replacing the motherboard, offering an immediate and cost-effective solution that saves both money and time.

The UGREEN CM477 adapter offers exceptional versatility, as it is compatible with a wide range of operating systems, including Windows 11/10/8.1/7/XP and Mac OS 8.6 or later. In addition, it works seamlessly with PS4, expanding your console’s audio capabilities. With a length of just 212mm and an ultra-lightweight design, it is ideal for carrying in your laptop bag. Its slim design ensures that its use does not block adjacent USB ports, allowing you to connect other peripheral devices simultaneously.
