Overall good soundbar

Good soundbar for the price. The volume control didn't sync with the TV at first, but it did later. Bass is good for just being a single bar. I had some audio sync issues in an app when I tried using audio passthrough, so I just disabled it, and the issues went away. With all the advanced features TVs have, you can get yourself into trouble if you mess with them too much. Overall, a good soundbar if you don't want one with a subwoofer.

Amazingly simple setup

I set this up during a fam ily meal about 10mins before sitting down to eat, it was that simple it took me all of 10mins to completely sort it including taking it out of the box and plugging it in as well as setting up the app and connecting it to the wi-fi, it's ridiculously straight forward. But that's not all, once set up it transforms the basic TV sound into a fully immersive sound rich environment that most importantly give crisp and clear speach even during sports or action films.

Amazing sound and base for movies !!

I brought this to add to my current setup. Out of the box it's simple to setup and connect to Bluetooth app on your mobile to check for any software updates. Once that's all done away you go. My tv has Bluetooth so I've only used that as a connection. It comes with brackets to easily fit to the wall. The sound quality is crystal you can hear all kinds of sounds that you've not heard before in movies and tv shows. The bass is fantastic !
