SMUGDESK USB External Sound Card with Volume Knob and 3.5mm Headphone Microphone Ports

SKU CH-YXFK-S2Z10

Adds a rotatable volume knob and separate 3.5 mm headphone and microphone jacks to any USB port without drivers

  • Separate 3.5 mm headphone and microphone jacks
  • Driver-free plug-and-play on Windows Mac Linux
  • Replaces faulty built-in audio ports
  • Professional chip reduces static for clear stereo sound

USB External Sound Card with Volume Knob

This compact USB audio adapter adds independent 3.5mm headphone and microphone jacks to any computer. It is designed for users whose built-in audio ports are damaged or noisy, and for anyone who wants quick physical volume control without opening software mixers.

Physical Volume Control and Dual 3.5mm Ports

A rotatable knob on the housing gives instant analog-style level adjustment for output volume. Separate 3.5mm sockets handle stereo headphone output and mono microphone input simultaneously, so a standard headset plugs in without a splitter. The adapter draws power from the USB bus and needs no external supply.

Driver-Free USB Audio Compatibility

The device follows the standard USB audio class specification, so Windows, macOS and Linux recognise it automatically with no driver installation. It works as a direct replacement for a faulty onboard port, but it cannot add features the host operating system does not already support through the USB audio class. It is not suited for users who need multi-channel surround outputs, dedicated line-level inputs or hardware DSP effects beyond basic stereo playback and capture.

  • Instant volume control via physical rotary knob
  • Separate 3.5 mm headphone and microphone jacks

Questions about this item

Will the separate 3.5mm headphone and microphone jacks work alongside my laptop's built-in speakers and internal mic?

Yes, the adapter adds independent 3.5mm output and input ports so you can keep using the laptop's internal audio devices at the same time.

How can I confirm the volume knob is controlling the USB sound card and not the system mixer after I plug it in?

Twist the physical knob; if the headphone volume changes immediately without opening OS settings, the knob is active on this adapter.

Does the package include a headset with a single 3.5mm plug, or do I need a splitter cable to use both jacks?

The box contains only the USB sound card with dual 3.5mm ports; a headset or splitter is not included and must be purchased separately.
