onn 20 in Bluetooth Soundbar vs Apollo S40 Pro Detachable Soundbar

The Apollo S40 Pro is the better-sounding and more flexible bar. It has two built-in subwoofers, a detachable left/right split, HDMI ARC and Bluetooth 5.3, and owners praise its bass and volume. The onn 20 in is smaller and lighter, adds multi-color LED lighting and works with Alexa, Siri and Google Assistant, but its 30 W rating, 1 in drivers and no real subwoofer leave it thin for movies. Buy the Apollo for TV and music; buy the onn for a small room, a secondary TV or a light-up look.

  • Choose the onn 20 in if you want a compact, light bar with LED lighting and voice-assistant pairing for a bedroom or secondary TV.
  • Choose the Apollo S40 Pro if you want real bass, HDMI ARC and a bar that splits into two speakers for a main TV.

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.

Apollo S40 Pro Detachable Soundbar

  • 4.9 / 526 ratings

Owners rate the S40 Pro very highly, calling the sound amazing, strong and loud for its size. They praise the bass from the built-in subwoofers and the build quality. Complaints center on wanting a separate subwoofer and on the app.

What people mention
  • SoundPraisedOwners call it amazing, strong and loud for a slim bar.
  • BassPraisedThe dual built-in subwoofers deliver bass owners notice.
  • BuildPraisedBuyers praise the materials and finish.
  • SubwooferCriticisedSome wish it had a separate subwoofer for deeper low end.

Questions and answers

Which is better for movies?
The Apollo S40 Pro. Its dual subwoofers and Movie mode give more bass and weight, and HDMI ARC keeps it to one cable and one remote. The onn bar is fine for dialogue but thin on action scenes.
Which has better bass?
The Apollo. It has two built-in subwoofers; the onn has one small built-in subwoofer and 1 in drivers at 30 W. Owners of the Apollo single out its bass as a strength.
Can I split the Apollo into two speakers?
Yes. The bar detaches into separate left and right speakers, which you can place apart for wider stereo. The onn is a single fixed bar.
Which is easier to set up?
Both are simple. The Apollo adds HDMI ARC, so one cable handles TV audio and the TV remote can control volume. The onn relies on optical or HDMI plus its own remote.
Is the Apollo worth stepping up to?
For a main TV, yes. You get more power, real bass, HDMI ARC and app modes. Step down to the onn only if space is tight or you want the LED lighting and voice assistants.
Which lasts longer?
Neither has a clear reliability edge from the data. The onn has a much larger rating base at 4.4; the Apollo's 4.9 comes from only 26 ratings, so treat it as early praise.
