Compact USB soundbar for tidy desks

The Cyber Acoustics CA-2890 is a 10 watt stereo speaker bar that draws power and audio from a single USB connection. It suits home-office workers, students and anyone who wants louder sound than built-in monitor speakers without adding a separate power brick or 3.5 mm cable.

Clip-on mount and on-bar controls

A spring-loaded clamp grips the top, side or bottom of monitors up to one inch thick, keeping the 1.3 by 8.3 by 2.8 inch bar centred under the screen. Touch-sensitive buttons on the front handle volume up, volume down, mute with an LED indicator and play-pause so adjustments stay at fingertips without reaching for keyboard shortcuts.

USB audio limits and fixed cable

The USB-A plug carries both power and signal, so the bar works only on hosts that supply 5 volt USB audio — no analogue 3.5 mm fallback is provided. The 65 decibel signal-to-noise ratio and 20 kilohertz upper frequency response are adequate for speech and background music but will not satisfy critical listening or high-fidelity playback.

Questions about this item

What USB standard does the CA-2890 use and what power does it draw?

The speaker bar uses a USB-A connection with an included USB-A to USB-C adapter and draws 5 V DC from the host port, so no separate power supply is needed.

How thick a monitor can the clip-on mount accommodate?

The clamp fits screens up to 1 inch thick and can attach to the top, side or bottom edge of the monitor.

How do I get audio playing after plugging the speaker bar in?

Plug the USB cable into the computer, select the CA-2890 as the default playback device in system sound settings, then use the on-speaker volume, mute and play/pause buttons to control audio.
