Our Verdict
Sonos Arc
onn. 42" 5.1. 2. Dolby Atmos Soundbar
The Sonos Arc is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. The Sonos is a bit different, as it's a 5.0.2 standalone bar with a more premium design that you can later upgrade with a sub and satellites. Still, it has better soundstage, surround, and Atmos performances. There are more sound enhancement features available, too, and DTS support. It can't reproduce as much bass on its own compared to the onn.
