onn 20 in Bluetooth Soundbar vs Sony HT-S100F Soundbar

The Sony HT-S100F is the better soundbar for most people. It is a 35-inch 2.0 bar with 120W, HDMI ARC, an optical input, USB playback and Sony's S-Force Front Surround, and owners consistently call it a clear step up from TV speakers. The onn 20-inch bar is much smaller and adds multi-color LED lighting, Bluetooth and a built-in subwoofer, but its 30W RMS rating and 1-inch drivers limit output and bass depth. Pick the onn for a small room, a secondary TV or a look with lights; pick the Sony for a main TV where dialogue clarity and volume matter.

  • Choose the onn 20 in soundbar if you want a compact bar for a bedroom or small TV and you like the multi-color LED lighting and built-in subwoofer.
  • Choose the Sony HT-S100F if you want a wider bar with more power, HDMI ARC and optical inputs, and a clearer upgrade over built-in TV speakers.

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.

Sony HT-S100F Soundbar

Owners generally see the HT-S100F as an easy, affordable step up from TV speakers, praising the simple HDMI ARC setup and the extra bass. Criticism centers on the lack of a subwoofer and limited surround effects.

What people mention
  • BassMixedOwners say the bass reflex cabinet adds punch over TV speakers but cannot match a dedicated subwoofer.
  • SetupPraisedReviewers like the single HDMI ARC cable and quick pairing with the TV remote.
  • SurroundCriticisedS-Force Front Surround is described as a modest widening effect rather than true surround.
  • DialogueMixedVoices are clearer than on TV speakers at normal volume but can get muddled in loud scenes.

Questions and answers

Which is better for a small bedroom TV?
The onn 20-inch bar. Its short width and 3.1 lb weight suit a small stand or wall mount, and the built-in subwoofer adds some low end at low volume. The Sony is nearly twice as wide and better suited to a main room.
Which sounds louder?
The Sony. It is rated at 120W total output against the onn's 30W RMS, and owners report it clearly outpaces TV speakers in a living room. The onn is fine for close listening but runs out of headroom.
Does either support Dolby Atmos properly?
No. The onn lists Dolby Atmos and Dolby Digital, but a 2.1 bar with 1-inch drivers and no height speakers cannot produce overhead effects. The Sony makes no Atmos claim and uses S-Force Front Surround instead.
Which is easier to connect to a TV?
The Sony, if your TV has HDMI ARC: one cable carries sound and lets the TV remote control volume. The onn also has HDMI but relies more on optical or AUX, and its extra inputs help only if you plug in other devices.
Is the Sony worth stepping up to?
Yes for a main TV. You get more power, a wider soundstage, sound modes and ARC control. Step down to the onn only if space is tight or you want the LED lighting.
Which lasts longer?
Both are simple powered bars with few failure points. The Sony has a longer track record and wider owner base; the onn is a store brand with a shorter history, so long-term reliability is less proven.
