USB-A External Sound Card

The UGREEN 40964 converts a standard USB-A port into external audio connections.

Connection

PC / Laptop USB-A → UGREEN 40964 → Headphones + Microphone

This makes it useful for desktop PCs and laptops where the built-in 3.5mm audio ports are unavailable, damaged, or inconveniently positioned.

Headphone & Microphone Connections

The adapter provides separate audio connections for playback and microphone input.

• Headphone Output: 3.5mm
• Microphone Input: 3.5mm
• Audio: Stereo
• Microphone Support: Yes

It is particularly convenient for headsets that use separate headphone and microphone plugs.

Important Headset Note

If your gaming headset has one combined 4-pole 3.5mm TRRS plug for both headphones and microphone, an appropriate headset splitter may be required to separate it into headphone and microphone connections.

Built-In Volume Controls

The adapter includes physical controls, allowing audio adjustments without relying entirely on software.

Controls

• Volume Up
• Volume Down
• Microphone Mute
• Audio / Headphone Mute

This is useful during gaming, online meetings, voice chat, calls, and everyday multimedia use.

Simply connect the USB-A plug to a compatible computer and select the USB audio device in your operating system if it is not automatically selected.

No separate external power supply is required.

The adapter can be used with compatible communication and gaming applications such as:

• Discord
• Steam voice chat
• Microsoft Teams
• Zoom
• Skype
• In-game voice chat
• Streaming applications

It provides a convenient way to connect separate headphones and a microphone through USB.

15cm Integrated Cable

The integrated cable helps keep the adapter away from neighboring USB ports and makes desktop placement more convenient.
