Cowin Bluetooth Soundbar for TV vs onn 20 in Bluetooth Soundbar

The onn is the safer pick for most shoppers: it has far more owner feedback and a higher rating, more inputs, and LED lighting. The Cowin is the one to consider only if you want a wider bar with a separate 60W subwoofer for more low-end punch. Reviewers of the Cowin complain about setup friction with ARC and Dolby, and its 3.9 rating reflects that. The onn is smaller and simpler, but its built-in subwoofer and 30W RMS mean less bass depth.

  • Choose the Cowin if you want a 32-inch bar with a separate 60W subwoofer and more total power for a larger room.
  • Choose the onn if you want a compact, well-rated bar with more connection options, LED lighting, and easier setup.

onn 20 in Bluetooth Soundbar

Questions and answers

Which is better for a large living room?
The Cowin. Its separate 60W subwoofer and 120W total power move more air than the onn's 30W built-in setup. The onn suits bedrooms and smaller TVs.
Which is easier to set up?
The onn. It has more ports and fewer reported quirks. The Cowin needs the TV set to PCM/stereo with Dolby/DTS off, and the cable must go into the ARC-labeled HDMI port.
Which has better bass?
The Cowin, because its subwoofer is a separate 60W unit. The onn's subwoofer is built into the bar, so bass is shallower and can distort at high volume.
Which lasts longer?
Neither has a clear reliability edge in the ratings. The onn's much larger review base and higher rating suggest fewer complaints, but both are budget bars with limited warranty support.
Is the onn worth stepping up to over the Cowin?
If you value more inputs, LED lighting, and a stronger owner rating, yes. If bass depth matters most, the Cowin's separate subwoofer is the better fit.
Do either support Dolby Atmos?
The onn lists Dolby Atmos and Dolby Digital support. The Cowin does not, and it actually needs Dolby/DTS disabled on the TV to avoid static.
