Vizio 2.1 Soundbar SV210M vs onn 2.1 Soundbar with Wireless Subwoofer

The onn 2.1 is the more flexible system: a separate wireless subwoofer, HDMI ARC, optical, USB and AUX inputs, plus a remote. The Vizio SV210M is a compact 30-inch bar with built-in subwoofers and Dolby Atmos support, but it lacks the input range and its bass comes from small integrated drivers. Owners rate the onn around 3.8 out of 5, with mixed notes on bass depth and build; the Vizio's plastic sides feel basic too. Buy the onn for a TV room where you want real low-end and multiple sources; buy the Vizio for a small space and a narrow TV stand.

  • Choose the Vizio SV210M if you have a narrow stand, want a one-piece bar with no subwoofer to place, and care about Dolby Atmos labeling.
  • Choose the onn 2.1 if you want a separate wireless subwoofer, HDMI ARC and optical inputs, and a remote in the box.

Questions and answers

Which is better for a small apartment living room?
The Vizio SV210M, because its built-in subwoofers remove a separate box and it is 30 inches wide. The onn's separate subwoofer adds bass but takes floor space.
Does the onn soundbar support Dolby Atmos?
No. Only the Vizio SV210M is listed as Dolby Atmos enabled. The onn handles standard 2.1 audio.
Which has better bass?
The onn, because its wireless subwoofer is a dedicated low-frequency speaker. The Vizio relies on small built-in subwoofers rated down to 50 Hz.
Can I connect a game console to either one?
The onn is easier: it has HDMI, HDMI ARC, optical and AUX. The Vizio offers HDMI and Bluetooth only.
Is the onn worth stepping up to over the Vizio?
If you want deeper bass and more inputs, yes. If space is tight and you want one piece, the Vizio is the simpler fit.
Which is easier to set up?
The Vizio: one bar, one HDMI cable, done. The onn needs the subwoofer paired and placed, plus batteries for the remote.
