The UGREEN CM129 (40964) is a practical USB external sound card designed to bring reliable audio connectivity to computers and laptops that lack working audio jacks. With a USB Type-A Male connection on one end and three separate 3.5mm female ports on the other, it lets you connect headphones, a microphone, or a single-plug headset setup—making it a convenient solution for everyday listening, calls, and basic recording needs.
This converter features three dedicated 3.5mm female ports: one for headphones, one for a microphone, and a combined option for a single-plug headset. That separation helps reduce confusion when setting up audio devices, especially when you need to switch between listening and speaking. Compared to using improvised adapters, having dedicated ports can make setup faster and more consistent for meetings, online classes, and gaming voice chat.
UGREEN CM129 includes external volume control along with separate mute buttons for earphones and the microphone. This means you can quickly adjust sound levels or mute only what you need—without digging through system settings. It’s especially useful during calls where you may want to mute your mic while still monitoring audio, or when you want quick volume changes for different environments.
Built with a smart noise-reduction chip (SSS1629), the CM129 is designed to deliver high-performance sound with a Signal to Noise Ratio (SNR) of 85dB. The frequency response range is 20Hz–20KHz, supporting a broad spectrum of audio for everyday use. For users who want a simple USB audio solution that can improve clarity compared to unreliable built-in ports, this converter provides a straightforward upgrade path.
The UGREEN CM129 is a simple plug-and-play device and does not require drivers. It works with Windows, Mac OS, and Linux, making it suitable for both desktops and laptops. An LED indicator light shows working status, so you can confirm the converter is active. This cross-platform support is helpful for households or offices where multiple operating systems are used.
With a cable length of 0.15 meter, the CM129 is designed for close-range connections—ideal for desk use where your USB port is near your audio devices. If you’re connecting a headset for gaming or a mic for basic voice recording, the short cable helps keep your setup tidy and reduces cable clutter around your workspace.
Choose the UGREEN CM129 if your laptop’s audio jack is broken, missing, or unreliable, or if you want a dependable USB audio converter for daily communication. It’s also a good fit for gamers who need headset connectivity, and for users who record voice for calls, notes, or simple content creation. If you want a straightforward way to add headphone and microphone support to a USB port—without complicated installation—this converter is a strong, easy-to-use option.
