Compact USB audio adapter

This empiremedia USB sound card adds a stereo input and output to a computer through a standard USB 2.0 connection. It operates at a 22 kHz sample rate with 24-bit digital audio and an 88 dB signal-to-noise ratio. The adapter draws 20 mA at 5 V and requires no driver installation on supported systems.

Casual listeners and remote workers

It suits anyone who wants a basic external audio device for music, video calls or movies on a laptop or desktop. Buyers who need higher sample rates, multi-channel surround sound or hardware volume controls should look at other options. The unit has no remote control and relies entirely on the operating system for noise reduction.

22 kHz 24-bit stereo specification

The deciding specification is the 22 kHz maximum sample rate combined with 24-bit depth, which limits the adapter to standard-definition stereo playback and recording. Frequency response spans 60 Hz to 22 kHz with an 88 dB signal-to-noise ratio. Compatibility covers Windows 2000 through Windows 10 and iOS via the native USB audio class.

Questions about this item

Does this USB sound card need a free USB 2.0 port on my computer to work?

Yes, it connects through a USB 2.0 interface and draws 20 mA at 5 V from that port.

Will the 22 kHz sample rate change how my existing headphones sound?

The adapter outputs 24-bit audio at 22 kHz with an 88 dB signal-to-noise ratio, so any analogue headset plugged into it will be limited to that specification.

How can I confirm the device is active after plugging it in?

The operating system will recognise it automatically without drivers, and sound will route through the adapter once it is selected as the output device.
