Cowin Sound Bar for Smart TV vs onn 20 in Bluetooth Soundbar

The onn 20 in is the safer pick for most people. It has a built-in subwoofer, more connection options and a much larger base of owner ratings, and owners generally find it easy to set up. The Cowin splits into two detachable bars and puts out more rated power, but it has no subwoofer and a smaller, more mixed review base. Buy the Cowin only if you want a bar that separates into two pieces or need the higher rated wattage.

  • Choose the Cowin if you want a soundbar that splits into two detachable bars for flexible placement, or you need the higher 50 W rated output.
  • Choose the onn if you want a compact bar with a built-in subwoofer, the widest input selection and a long track record of owner ratings.

Questions and answers

Which is better for a small living room TV?
The onn. Its built-in subwoofer and compact 20 in bar suit tight spaces, and setup is simpler. The Cowin is wider when joined and has no subwoofer.
Which has better bass?
The onn, because it has a built-in subwoofer. The Cowin relies on four full-range drivers with no dedicated bass driver.
Which is easier to set up?
The onn. The Cowin needs the dedicated ARC port, PCM output selected on the TV and the optical cable cap removed, which trips up some owners.
Is the Cowin worth stepping up to?
Only if you want the detachable two-bar design or the higher rated wattage. On bass, inputs and owner ratings the onn comes out ahead.
Which lasts longer?
Neither has a published lifespan. The onn has a much larger owner base, which gives a steadier read on reliability over time.
