Kopul's compact USB desktop volume controller adds a tactile volume knob and media controls to computers, laptops, tablets, and smartphones without extra drivers or setup. Turn the knob to adjust system volume, press to mute or unmute, or press while turning to skip tracks. A temporary on-screen display provides playback controls and disappears after four seconds, while the switchable ring light supports use in dim rooms. Its black aluminum body, nonslip feet, compact footprint, and compatibility with macOS, iOS, Windows, and Android make it practical for music, gaming, videos, DJ sessions, and online meetings.

 

Kopul's compact USB desktop volume controller gives users a physical knob for adjusting system audio on computers, laptops, tablets, and smartphones. It controls playback volume whether audio is heard through internal speakers or headphones, making it useful for music, gaming, video viewing, DJ sessions, and online meetings.

Turn the knob to change the volume. Press the knob once to mute or unmute the audio without pausing playback. Press down while turning the knob left or right to move to the previous or next track.

Turning the knob opens a temporary display in the upper-left corner of the screen. The display provides volume, play, pause, previous-track, next-track, and mute controls without requiring users to leave their current window or application. The display disappears after four seconds of inactivity.

A subtle illuminated ring helps users locate the controller in dim rooms. Press and hold the knob for eight seconds to turn the ring light on or off.

The aluminum housing and nonslip feet provide a stable, compact desktop footprint. The controller connects through its USB Type-C port to a USB Type-A port on the host device using the included cable. It operates without additional drivers or setup.

Published compatibility includes macOS, iOS, Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and Android. Computers equipped only with USB Type-C ports require a compatible USB Type-A to USB Type-C adapter.

Compatibility Note: This controller is not designed to control Digital Audio Workstation software.
