What People Are Saying

Rated 5 out of 5 by from YOU ARE THERE I purchased this product at Best Buy, as a open box return. I hooked it up to my smart TV, and the experience I get from watching action movies AND live concerts, is the same as really being there. The sub woofer gives me the just like you're there feeling. And the REAR speakers actually through the sound ALL AROUND.

Rated 2 out of 5 by from Mediocre sound, not crisp and clean I've had this for several months and am very disappointed. The sound emanating from the unit is not always crisp and clean, and there is no way to adjust if other than with the built-in Cinema and ASC buttons, which don't provide much in the way of improvement. I called customer service and they had me reset the unit, but no improvement. Problem is exacerbated when I try to play the unit a lower volumes.

Rated 5 out of 5 by from Awesome sound and easy to set up This unit is an amazing buy for the cost. Took me less than 20 minutes to unbox and set up. The wireless components seemlessly pair to the soundbar without any effort and the sound is awesome. Buy this unit! If there is a downside it's that you need three plugs, (Soundbar, subwoofer, rear speaker receiver).

Rated 4 out of 5 by from Very good sound quality I enjoy the product. It certainly boosts the speakers in the 43" LG TV I have. The only thing to watch out for is feedback in the Web OS screen sometimes where you have to do a hard reset.

Rated 4 out of 5 by from Great sound I bought this a couple of weeks ago. It was a quick and easy set up. The sound is great! We use it for movies, shows, and music. Pairing with Bluetooth is simple.

Rated 4 out of 5 by from Decent Sound I bought this set separately (which was more expensive at the time) in May of 2017 and I am overall satisfied. The quality of sound is superb, although I'll occasionally receive some interference between the bluetooth connection and the subwoofer will black out and come back on. Additionally, while the soundbar is great, I also have an LG tv the produces great sound, so I do not believe it is completely necessary. Setup was very simple and quick. The remote is user-friendly and I like the LED status display on the sound bar. I also use it to listen to music as well. My only other problem is that while watching shows that don't support surround sound will overpower the dialogue. Other than those few things, it's definitely worth the promotional price.

Recommended sound bar mounting bracket to mount under TV? I have an LG 65sj8000?

Asked by: Bluebino
You can mount the main unit for the LG 4.1 ch Sound Bar Surround System with Wireless Surround Sound Speakers, Model # SJ4R on the wall using the Wall bracket install guide, and the two Wall brackets that come supplied with the unit. You will need to purchase the screws and wall plugs to attach the wall brackets to your wall...^IFV

I have this soundbar and it is hooked up to my 60UH8500 LG TV via optical cable. My problem is that when watching a movie, it almost seems as though there is no dialogue (center) channel. During music (such as the movie Muana) the lyrics are very muffled.

Hello, please see page 33 in the manual to see if you can adjust the settings to meet your needs. ^AC

Does this work with my LG 60" SJ8000 TV? Does it have to be connected or will

I just got the SJ4R and can't get any sound to come thru. I don't have the optical plug on my tv. I have HDMI but it isn't the ARC. Is there another wire I can get or is this just not compatible? My tv is LG so I thought this would connect, but it isn't.

Asked by: SW322
For sound to come through, you must be sure to turn off the internal speakers of the LG TV. Please come talk to us on Twitter at @LGUSSupport, on Facebook at @LGUSSupport or give us a ring at 1-800-243-0000 so we can see what is going on. ^AC
