Although we haven't reviewed this specific Sony 2.1-channel soundbar, this 2019 model looks like a real contender with similar credentials to the top performers in our best soundbars round up. 

The fact that the Sony is a 7.1.2ch Dolby Atmos/DTS X with Vertical Sound Engine soundbar with a built-in subwoofer, means that it's likely to make a big impression on your TV viewing. There are 7 different sound modes to enhance your entertainment experience, boosting movies and drama soundtracks with plenty of powerful bass energy to bring on-screen action to life, and give soundtracks real scale. There's a voice enhancement mode, too, promising greater clarity. 

Measuring 35 inches long, the Sony is ideal for small to medium-sized TV rooms. Audio compatibility runs to Dolby Digital and DTS formats, and surround sound expansion mode is intended to make movie soundtracks more immersive by creating a pseudo surround sound effect. 

Connectivity includes HDMI with eARC support and optical digital audio ports, and the soundbar comes supplied with a remote control so that you can tweak the settings and adjust the volume level from the comfort of your sofa.
