UGREEN 30724 External USB Sound Card – 3.5mm Headphone + Microphone Adapter – Black (Open Sealed)

Description

The UGREEN 30724 External USB Sound Card is a compact USB audio adapter designed to add or replace 3.5mm audio ports on compatible PCs, laptops, consoles, and other USB host devices.

It converts a standard USB-A port into two separate 3.5mm audio connections:

• Stereo Headphone / Speaker Output
• Mono Microphone Input

This makes it useful for computers with a faulty sound card, damaged audio port, or systems that need separate headphone and microphone connections through USB.

The adapter supports 16-bit ADC/DAC audio at 48kHz, includes a built-in audio chipset designed to reduce interference, and uses a short 20cm integrated cable so it does not block nearby USB ports.

• TRRS 4-Pole Combined Headset Plugs

through the microphone input itself.

Important 2-in-1 Meaning

The “2-in-1” description refers to:

It does not mean the adapter has one universal 4-pole TRRS headset jack.

The two 3.5mm ports are separate audio connections.

Important USB-C Note

This model uses:

USB-A

It is not a USB-C sound card.

A separate compatible USB-C-to-USB-A adapter would be required for a USB-C-only host if that host supports USB audio through the adapter.

Important Headset Plug Note

If the headset uses a single:

3.5mm TRRS 4-Pole Plug

for both headphones and microphone, it may require a:

TRRS → Separate Headphone + Microphone Splitter

before connecting to the UGREEN 30724.

Important Audio Quality Note

The adapter supports:

16-bit / 48kHz

It should not be advertised as a 24-bit / 96kHz or Hi-Res DAC.

This product is designed primarily for everyday audio, gaming communication, calls, and basic external sound-card replacement.
