USB sound cards are external adapters that plug into a computer's USB port and add headphone and microphone sockets. This category holds a few models from LogiLink, InLine, Micro Connect and Exertis Connect. They help when the built-in audio has failed, when a PC lacks sockets, or when a laptop needs to be connected to a headset.
How to choose a USB sound card
Sockets and connections. Decide first what you need to plug in. The simplest adapter has separate 3.5 mm headphone and microphone sockets, while a model with a single combined socket suits headsets with one plug, like those supplied with many phones. If you use separate PC headphones and a microphone, choose two sockets.
Audio channels. Most USB audio adapters output stereo sound, which is enough for music, films and video calls. Some descriptions mention 5.1 or 7.1 sound, but this is usually virtual surround through headphones rather than extra physical outputs. Check the specification for the number of real outputs.
Compatibility. Basic USB audio adapters generally work without extra drivers on Windows, macOS and Linux, but models with additional controls may need the manufacturer's software. Look at the plug as well: if your computer only has USB-C, you will need either an adapter of that type or a converter.
Sound quality and headphones. Look at the digital format the device supports, such as 16 or 24 bit and 48 or 96 kHz. High-impedance studio headphones need a stronger headphone amplifier, because a basic adapter may drive them too quietly. Low-impedance headphones and headsets usually need nothing more.
Controls and convenience. Buttons for volume or muting the microphone are handy during calls, as you do not need to dig through system settings. If the adapter plugs into the back panel of a desktop PC, cable length matters too.

Frequently asked questions
What is a USB sound card used for?
A USB sound card is used when a computer's built-in audio output is faulty, noisy or short of sockets. It also lets you connect a separate headset or microphone to a laptop. It is a cheaper fix than replacing an internal sound card.
Does a USB sound card need drivers?
Usually not. Most basic USB audio adapters are recognised automatically as a standard audio device, so they work on Windows, macOS and Linux. Drivers or an app are only needed for models with extra effects or advanced settings.
Will a USB sound card improve sound quality?
Often it will, especially if the computer's built-in audio produces hiss or interference. An external adapter converts the signal away from the electronics inside the computer, so there is less noise. It will not help if the real problem lies with the headphones or a poor recording.
How do I connect a USB sound card and use it as the default audio device?
Plug the adapter into a free USB port and wait for the system to recognise it. Then choose it as the default output and input device in the Windows sound settings, or in the Sound section of macOS System Settings. Finally, plug your headphones and microphone into the adapter's sockets.
