Rated 3 out of 5 stars
Looks very nice, but average sound quality
First things first since this is not well-documented anywhere: this GX OLED model-matching soundbar matches the width dimension of the 65 inch GX OLED only. This was perfect for me since I have that TV on the wall as well, and aestehtically it does match the GX beautifully on the wall (see pictures). That is the main selling point of this soundbar, and should be the only reason you're considering purchasing it. If you don't have a LG GX OLED, don't purchase this, there's better soundbars out there! As for the negatives, the sound quality is not the greatest in the world. Specifically, ALL low frequency sounds are offloaded to the subwoofer, which means no natural bass or low frequency sound comes directly from the soundbar speakers. Part of this is just raw physics given how slim the soundbar is in order to sit flush against the wall, which makes it impossible to engineer speakers that produce satisfactory low frequencies. The downside of this, is that if you turn the volume of the subwoofer down to avoid disrupting rumble, you're also turning down low frequency in things like speech/voice as well, since the sound output is so intrinsically linked as a single engineered system. Another negative is how difficult LG makes it to find the correct smartphone app to control this unit (the one you want is LG Music Flow Bluetooth); however, once you do, the app has all the settings you'd need, including independent volume controll of the subwoofer and optional rear LG speakers (which I purchased and paired with these, and they work great). Finally, LG does not do a great job documenting which of the Sound Effects work best for certain situations. Through trial and error, I've found the "Movie" setting provides the most consistent sound quality for my 5.1 setup with the optional rear speakers (I don't particularly like how the AI effect consistently makes the rear channel quieter than it should be with non-Atmos content). Overall, these speakers look fantastic when paired with a GX OLED, but are very mediocre in every other way, which makes it hard to justify the very high price tag for average consumers.

Awesome setup
This sound-bar is amazing. It connects flawlessly to my LG G2. It really sounds like I am in a movie theater. The Bluetooth mode sounds great when I stream from IPhone. The design is sleek and modern.
