Compact speaker bar for desk use

The Cyber Acoustics CA-2890BT is a single 2.0 speaker bar that clamps to a monitor and draws power from a USB port. It adds a built-in microphone with mute control for hands-free calls and includes a USB-A to USB-C adapter for newer laptops.

Suits users who want one device for PC audio

It works well for video meetings, background music and casual video playback at a desk. Buyers who need room-filling sound, deep bass extension or a separate subwoofer should look elsewhere. It also does not serve as a surround-sound system.

Dual 1.5 drivers deliver 10 watts total power

The 20000 hertz upper frequency response and 70 decibel signal-to-noise ratio cover voice and general media cleanly. Output is adequate for near-field listening at typical office volumes. Larger rooms or critical music listening will exceed its comfortable headroom.

Questions about this item

Does my computer need a free USB-A port to power and use the CA-2890BT speaker bar?

The speaker bar draws power from a USB connection and includes a USB-A to USB-C converter, so it works with either port type on your PC or Mac.

Can I keep my existing wired headset plugged in while the CA-2890BT handles Bluetooth calls from my phone?

Yes, the speaker bar connects to your computer via USB and to a smartphone via Bluetooth 5.0 simultaneously, letting you switch audio sources with the multi-function button.

How do I confirm the CA-2890BT is receiving audio and the microphone is live after clamping it to my monitor?

The built-in LED indicator shows mic mute status, and the touch controls let you adjust volume or switch between USB and Bluetooth modes for immediate feedback.
