Compact USB-powered stereo speakers

The Cyber Acoustics CA-2110USB is a 2.0 speaker system that draws power and audio from a single USB connection. It includes an attached USB-C to USB-A adapter for compatibility with both port types. The round, black satellites measure 4.2 in x 4.4 in x 8.7 in and weigh 0.689 kilograms total. Plug-and-play operation requires no 3.5 mm jack or external power adapter.

USB audio and power delivery limits

Audio and power share the same USB link, so output is constrained by the port’s 5 volt supply. The system delivers 10 watts total RMS power with a 65 decibel signal-to-noise ratio. A 4.5 foot cable runs from the USB plug to the right speaker, and a 3.3 foot cable connects the left satellite. No separate power brick or audio cable is used.

Upward-firing drivers for near-field listening

Each satellite uses an upward-firing driver angled to project sound toward the user at desk level. Frequency response reaches 20000 hertz at 4 ohm impedance. The design suits music, video calls and point-of-sale audio in compact workspaces. Buyers needing room-filling volume, deep bass extension or a subwoofer output should consider larger systems.

Questions about this item

Should I choose the CA-2110USB over other Cyber Acoustics models like the CA-2890 soundbar?

The CA-2110USB is a stereo 2.0 speaker pair with upward-firing drivers, while the CA-2890 is a single soundbar; choose this model if you want separate left and right channels on your desk.

What does the 10 watt rating mean for actual listening volume?

The system delivers 10 watts RMS total from both speakers combined, powered entirely by a 5 volt USB port, which is sufficient for clear music, video and voice calls at a desktop.

How does the USB connection affect audio quality compared to a 3.5 mm jack?

The single USB cable carries both digital audio and power, so no separate 3.5 mm analogue connection or power adapter is needed; an attached USB-C to USB-A adapter is included for either port type.
