onn 20 in Bluetooth Soundbar vs Samsung HW-C400 Soundbar

Both are small 2.0 bars with built-in bass, so pick by what you value. The onn adds multi-color LED lighting, more input types (HDMI, optical, USB, AUX, 3.5 mm) and voice-assistant compatibility, and its 8,979 ratings average 4.4. The Samsung HW-C400 is the safer buy for TV dialogue: Voice Enhance, Night Mode, One Remote with a Samsung TV, NFC pairing and a 1-year warranty. Owners of budget bars in this class report modest bass and narrow stereo either way.

  • Choose the onn 20 in soundbar if you want LED mood lighting, the widest set of wired inputs, and Alexa or Google Assistant compatibility in a compact bar.
  • Choose the Samsung HW-C400 if clearer TV dialogue, a night mode and one remote for a Samsung TV matter more than lighting and extra ports.

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.

Samsung HW-C400 Soundbar

Owner feedback on this entry-level Samsung bar is limited, but the pattern is that it clearly beats TV speakers and is easy to set up. Buyers note the bass is present but not room-shaking, and dialogue mode helps with news and drama.

What people mention
  • BassMixedOwners say the built-in woofer adds low end but does not hit like a separate subwoofer.
  • DialoguePraisedVoice Enhance is called out for making speech easier to follow.
  • SetupPraisedPairing with a Samsung TV over Bluetooth is described as quick and cable-free.
  • SoundstageCriticisedListeners find the 2.0 layout narrow compared with multi-channel bars.

Questions and answers

Which is better for hearing TV dialogue?
The Samsung HW-C400. Its Voice Enhance re-tunes the equalizer to push voices forward, and Night Mode keeps dialogue audible at low volume. The onn has no equivalent feature.
Which has better bass?
They are close. Both use a built-in woofer in a small cabinet, so bass is fuller than TV speakers but short of a separate subwoofer. Neither will pressurize a large room.
Do I need a Samsung TV to use the HW-C400's remote?
No. The bar works over Bluetooth, optical or HDMI with any TV. The One Remote only controls both devices together when the TV is a Samsung.
Which connects to more devices?
The onn. It adds a 3.5 mm jack and AUX on top of HDMI, optical and USB, so older consoles, PCs and MP3 players plug in directly. The Samsung relies on HDMI, optical, USB, Bluetooth and NFC.
Is the onn worth stepping up to over the Samsung?
Step up to the onn only if you want LED lighting, more wired inputs or voice assistant control. For pure TV sound, the Samsung's dialogue and night features are more useful day to day.
Which is easier to wall mount?
Both are wall mountable and under 3 in high. The onn is 20 in wide and 3.1 lbs, so check your bracket width; the Samsung lists a 2.6 in height with no width given.
