Compact USB soundbar for clutter-free desks

The Cyber Acoustics CA-2890 is a 2.0 stereo speaker bar that draws power and audio from a single USB connection. It clamps to a monitor or stands alone, making it suited to home offices, students and anyone who wants sound without extra cables or a wall outlet.

Replaces separate speakers and 3.5 mm cables

A single USB-A cable handles both power and signal, removing the need for a separate audio jack and power brick. The jump is worth it when desk space is tight, when a laptop has no 3.5 mm port, or when you want volume, mute and play/pause controls at your fingertips.

Check USB port type and monitor clamp clearance

The box includes a USB-A to USB-C adapter for newer laptops, so verify which port you will use. The clamp fits top, side or bottom edges; measure the bezel thickness and curve to ensure a secure grip before ordering.

Questions about this item

How wide is the monitor clamp opening on the CA-2890 speaker bar?

The bar measures 8.3 inches wide and clamps to the top, side or bottom of most monitors; the clamp adjusts to fit typical bezel thicknesses without tools.

What is the correct order to connect the USB cable and the USB-A to USB-C adapter on a laptop with only USB-C ports?

Plug the adapter into the laptop's USB-C port first, then insert the speaker's USB-A plug into the adapter; reversing the order can prevent the device from being recognised.

How should I clean the driver grille if dust builds up after months of use?

Power off the speaker, then gently brush the grille with a soft dry brush or use low-pressure compressed air; avoid liquids or vacuum nozzles that could damage the dynamic driver.
