    • Nice system great with LG TVs
Have owned a few lg sound bars and always felt they produce good sound. Have this paired with a LG 75 inch mini led tv and pairs very well. Like the option to use the TV speakers and sound bar. Seems like the focus now is on clarity and surround sound feel like the bass is a little less then I would like but still very good and clear. Good system for the price even better with an LG tv. Also recommend the lg app gives you control ability and a few more options to tweak the sound. ... show more

Worked extremely well, plug and play. We did nothing but plug it in and turn on the TV. It instantly recognized soundbar. Much clearer audio, works great

    • This is a good addition to ourlg\
We got this system for our LG tv, got a bracket to mount the sound bar underneath the tv, it was pretty easy to hook up. We are pleased with the sound, works pretty seamlessly with the tv.

    • Nice quality and design good balanced sound
Since I own LG tv I decided to pair it with LG soundbar. Connection is easy and stable. Fits perfect under the TV. Sound quality is pretty good, clear dialogs, clear mid, good tribble. I expected little bit more deep bass surround from sub but still bass is pretty good and balanced, rather I prefer deep bass surround sound. Good thing is AI built sound system controls what mode are you in and what exactly are you watching and adjust the sound for you also you can use your own settings through the app. Overall I like the sound quality and design would recommend it especially for LG tv users. Huge sound upgrade vs TV speakers. ... show more

    • Rear speakers impossible to find, but otherwise a nice bar
First off, do like several other reviews say and never enable "AI Sound" and enable Auto Volume. I'm guessing that "AI Sound" depends on using a satellite or cable service and it defaults to max clarity. Cinema gives the best sound typically on every LG sound bar I've used, including this one. Now, as for the bar itself, it's excellent for a "basic" sound bar, basic in the respect that it doesn't include diagonal facing drivers, more than one up firing driver, wireless rear speakers, and other more fancy things. It has the option to connect rear speakers, LG SPT8-S is the model, but I can't find them anywhere in the USA. Amazon Brussels has them, ASIN B0D4R92D5X on Amazon.com.be, sold and shipped by Amazon, but they don't ship to the USA. You can attach it to the back of most of the LG OLED models for a floating effect if it's wall mounted, but it fits nicely under the LG C4 OLED with its included stand. Connectivity is your standard HDMI eARC, TOS Link (Optical), Bluetooth (primarily for phone casting), or Wireless Sound Sync. All options other than eARC only support compressed formats, so stick with eARC if you can. Setup is easy, you do everything from the LG phone app like you can with modern LG TVs. I'm not a huge fan of it lacking stand alone WiFi/Ethernet connectivity so you can't, say, stream media from a media server directly to it, or cast high quality audio from a phone, but that also reduces IoT attack surfaces. It supports 4K 120hz passthrough so you can simplify setup to one cable to the TV from a streaming box or gaming console. The sound is excellent in everything from movies to sports to TV shows. With Dolby Atmos sources it will rattle your walls without noticeable distortion even on 80% volume so movies have that proper punch. The sound bar itself keeps the mid and high ranges nice and clear without being tinny, so everything from classical music to sports to movies really shine. Outside of Dolby Atmos sources it does tend to be on the treble side, but those sources aren't generally tuned to be cinematic in quality, but it's not -tinny-. Overall it's an excellent system. It'd be great if the SPT8-S rear speaker kit were more available, but as it is if you don't really have room, need, or the ability to place rear speakers, I see no reason not to grab this sound bar if you have an LG TV. ... show more

    • Tricky installation but good soundbar
Excellent sound. Installation was problematic. I have an LG -C5 OLED, so figured it would be a seamless quick installation through the HDMI ARC. However I could not get the TV remote to control the volume for the soundbar. After an hour of frustration including reinstalling a number of times I hit google and came across a suggestion to disconnect any other devices connected to an HDMI in the TV and then install the soundbar, then plug the other HDMI's back in. Worked like a charm and now get all the features including the WOW Orchestra connection. Wish the instructions provided this info -- would have saved a lot of frustration. Also, it is helpful to download the LG soundbar app or the Thin Q app to more easily set the sound levels. Other than that, so far (after 1 day) like it! Update: frustrating sound board. The wow orchestra feature repeatedly disconnects requiring a complete reinstall to get it to work. Lg needs to improve their product ... show more

    • Matched this LG Soundbar with the new LG TV I purchased. Great team!
I purchased this Soundbar because I got a new LG TV and worked with Alexa to get this one which was a good match with an acceptable price. It arrived on time and in good condition. It was easy to set up, but these new remotes present a real learning curve for an older person, but I have gotten it working well with the TV now. I'm very pleased with my purchase. ... show more

    • Big improvement from the TV speakers
I had a good experience with this soundbar. It gave movies and TV a much fuller sound than the built-in speakers, and the separate subwoofer added a lot more punch without needing a complicated setup. Overall, it was an easy upgrade that made a noticeable difference.
