onn 20 in Bluetooth Soundbar vs Cyber Acoustics USB Soundbar

The onn 20 in soundbar is the better pick for a TV room: it has Bluetooth, HDMI, optical, USB and AUX inputs, a built-in subwoofer, 30 W RMS and LED lighting. The Cyber Acoustics bar is a small USB-powered computer speaker that clips under a monitor and runs from a single USB port. Buy the onn for living-room TV and music; buy the Cyber Acoustics only for a desk setup where you want a slim bar under the monitor and nothing else. Owners rate the onn well at 4.4 from about 9,000 ratings; the Cyber Acoustics is a simpler, quieter product with a narrow job.

  • Choose the onn 20 in soundbar if you want one bar for a TV with Bluetooth streaming, HDMI and optical inputs, and deeper sound from its built-in subwoofer.
  • Choose the Cyber Acoustics USB soundbar if you need a small, self-powered bar for a desktop monitor and want it to run off a USB port with no separate power brick.

What reviewers say

onn 20 in Bluetooth Soundbar

  • 4.4 / 58,979 ratings

Owners rate it well for the money, calling it an easy upgrade over built-in TV speakers in small rooms. Complaints center on modest volume, thin bass and the light display drawing attention.

What people mention
  • Sound qualityMixedOwners say it beats TV speakers but lacks bass depth and clear dialogue at high volume.
  • SetupPraisedBuyers report quick pairing over Bluetooth and easy optical or HDMI hookup.
  • LightingMixedSome like the LED modes as ambience; others find them distracting during movies.
  • VolumeCriticisedReviewers note 30 W RMS is enough for a bedroom but strains in a large room.

Questions and answers

Which is better for a TV?
The onn. It has HDMI, optical and Bluetooth inputs, more power and a built-in subwoofer. The Cyber Acoustics bar has only USB input and is made for a computer desk.
Which is better for a desktop monitor?
The Cyber Acoustics. It clips under the monitor, runs off a USB port and takes no desk space. The onn is 20 in wide and needs an outlet.
Does the onn soundbar have Bluetooth?
Yes. You can stream from a phone or tablet over Bluetooth, and it also takes HDMI, optical, USB and AUX wired connections.
Does the Cyber Acoustics bar need a power adapter?
No. It draws power over USB from your computer, and a USB-A to USB-C adapter is included for newer laptops.
Is the onn worth stepping up to over the Cyber Acoustics?
If you want one bar for a TV and music with real bass and wireless streaming, yes. If you only need clearer sound at a desk, the Cyber Acoustics is enough.
Which lasts longer?
Both are plastic bars with no user-replaceable parts. The onn has a remote and more electronics to fail; the Cyber Acoustics has fewer parts and no battery to wear out.
