USB-A stereo adapter for laptops and desktops

The Sabrent AU-MMSA adds a 3.5 mm stereo headphone output and a separate 3.5 mm mono microphone input through a single USB-A port. It is recognised as a standard USB audio device on Windows, Mac and Linux without installing drivers. The adapter draws power from the USB bus so no external supply is needed. It suits users whose onboard audio jack has failed or is missing entirely.

Compact dongle with two dedicated jacks

The green jack handles stereo output for headphones or powered speakers while the pink jack accepts a mono microphone. A 4-pole headset with a combined plug is not supported and passive speakers cannot be driven. The body measures 1.6 cm by 7 cm by 10.4 cm and weighs 0.02 kilograms with a short 1.5 by 0.4 by 0.9 inch cable tail. IT policies on managed machines may block new USB audio devices.

Replaces a broken or absent onboard port

This adapter restores basic stereo in and out when a laptop or desktop headphone socket fails or was never fitted. It operates at 48 KHz with a 98 dB signal-to-noise ratio and complies with the USB Audio Device Class 1.0 specification. The jump is worth it when a simple, driverless stereo connection is required and surround sound or combo-headset support are not needed.

Questions about this item

Does the USB 1.0 audio class limit the adapter to 48 KHz stereo?

Yes, the device follows the USB Audio Device Class 1.0 specification and outputs stereo at 48 KHz with a 98 dB signal-to-noise ratio.

What physical space does the adapter need beside a USB-A port?

The dongle measures 1.6 cm wide, 7 cm deep and 10.4 cm high, so allow roughly that much clearance next to the port.

How do I make the adapter the default input and output in Windows?

After plugging it in, open Sound settings, choose the Sabrent device for both output and input, then confirm the green jack is used for headphones and the pink jack for a mono microphone.
