onn 20 in Bluetooth Soundbar vs Cowin 17-Inch Bluetooth Soundbar

The onn 20 in is the safer pick for most shoppers. It has a much larger owner base, a 4.4 rating from nearly 9,000 ratings against 3.8 from 264, and more inputs: optical, USB, HDMI, AUX and 3.5 mm. The Cowin is shorter at 17 inches and simpler, with Bluetooth, HDMI and AUX only. Neither is a true surround system; the onn lists Dolby formats but its 1-inch drivers and 30 W RMS keep it a small-room bar. Buy the onn for input variety and lighting, the Cowin only if the narrower width fits your shelf.

  • Choose the onn 20 in if you want the most inputs, a built-in subwoofer and LED lighting in a compact bar.
  • Choose the Cowin 17-Inch if you need a narrower bar and only plan to use Bluetooth, HDMI or AUX.

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.

Cowin 17-Inch Bluetooth Soundbar

  • 3.8 / 5264 ratings

Ratings are mixed-to-positive at 3.8 out of 5 from 264 ratings. Owners treat it as a cheap way to make a small TV clearer, not as serious audio gear.

What people mention
  • Sound qualityMixedOwners say it beats built-in TV speakers but lacks bass and depth.
  • SizePraisedThe 17-inch cabinet fits small TVs and shelves where wider bars don't.
  • BluetoothPraisedPairing with phones and tablets is quick and reliable for most buyers.
  • BuildCriticisedThe plastic body feels light and cheap to some owners.

Questions and answers

Which is better for a small bedroom TV?
The onn. Its built-in subwoofer and optical input suit a TV in a small room, and the 20-inch width still fits most stands. The Cowin works too but gives you fewer ways to connect.
Does the onn really do Dolby Atmos?
It lists Dolby Atmos and Dolby Digital, but a 2.1 bar with 1-inch drivers cannot produce height effects. Treat it as stereo with a subwoofer, not as an Atmos system.
Which one lasts longer?
Neither brand publishes a lifespan figure. The onn has far more owners reporting over years of use, which is the better signal you have. The Cowin's smaller track record makes it harder to judge.
Is the Cowin worth stepping up to?
No. It has fewer inputs, no subwoofer and a lower owner rating. Pick it only if the 17-inch width is the deciding factor.
Can I wall mount either bar?
The onn lists a wall-mount style and stands 2.52 inches high. The Cowin's mounting details are not listed, so check its box before drilling.
Will either work with a voice assistant?
The onn lists Alexa, Google Assistant and Siri compatibility, though it has no built-in microphone. The Cowin lists no assistant support.
