Rated 5 out of 5 by from Great sound and design Bought this soundbar to go with my LG tv which I also reviewed here. I liked my stock sound settings but I was interested in adding a soundbar for movie nights. I wanted to stay in the family because I hate having mix matched products unless it's absolutely necessary. I found a great deal on this set and I was so happy I pulled the trigger on it. I read reviews and I was debating between this set or the SH7B model. I like the SH7B because of the small profile as well as the features, but when this set went on sale I knew my choice was made for me. I absolutely love the sound this thing puts out. Honestly it's a little too loud at times. I live in an apartment with multiple neighbors so I have to keep it down or off on week nights. It has great bass and the features is what puts it over the top for me. It has chromecast built in and I can stream music directly from my Google home. It also supports HDMI ARC which allows me to connect to my tv and use only my tv remote. It also has wifi and internet connectivity as well as Bluetooth for a multitude of wireless steaming options. You can even add more speakers to it to create a true surround sound experience. Design profile is amazingly sleek and slim. It's also designed to fit tvs from 50-65 inches, and has a separate mount for the LG OLED models. Overall I love this purchase probably even more than my tv itself. Definitely worth the buy.

Rated 5 out of 5 by from Great sound for the money and size. We needed a sound solution for our console mounted OLED LG TV. Because of decorating and room considerations we did not want to go with a multi speaker system requiring floor or wall mounting. This low profile sound bar fits unobtrusively in front of the TV and doesn't interfere with any remote functions. It is easy to pair with the TV and syncs perfectly. The subwoofer is easy to place as it is connects wirelessly. The system greatly enhances our listening pleasure.

Rated 3 out of 5 by from Failed to play sound simultaneously This sound bar is unable to play sound simultaneously with LG OLED C7 TV. I tried it in different connection setting ; optical , HDMI ARC and even gave a shot with sound sync Bluetooth option. Indeed, I do have the choice of simultaneously play sound in TV general sound setting but all I got was listening to sound came from internal TV speakers only ( the sound turned itself off after a while because it is of non usage..!!)

Rated 2 out of 5 by from Flawed sound bar, flawed support Wish I would have went with something else. I DO NOT NEED AN LCD ON MY SOUNDBAR THAT I CANNOT SHUT OFF. It's a distraction. Customer support tells me I wouldn't know the input it was on if I shut it off, essentially calling me stupid. I will be returning and anyone considering should avoid.

Is it possible to disable the Bluetooth on this sound at? I have a neighbor who connects to it by mistake and it’s very frustration to have the system change the source.

Asked by: TxHogFan94
Hello, please go to the manual, page 55. Once there, set up a Bluetooth connection and then set BLUETOOTH connection lock on page 57. ^AC

Is it possible to directly connect the SJ8 sound bar to an OLED lg55b7? While mounted to a wall mount that comes off the wall? I know they have the T8, but that seems to be for sitting on a table

Asked by: DONR60
Hi DONR60. The LG Sound Bar Bracket Stand, Model # T8 is not designed for sitting on a table. It is designed to have the Sound Bar be mounted directly under the 2017 OLED TVs while they are mounted on the wall. The LG B7 OLED 4K HDR Smart TV - 55" Class (54.6" Diag), Model # OLED55B7P has an Optical Digital Audio Output that you can connect directly to the Optical Digital Audio Input on the LG 4.1 ch High Resolution Audio Sound Bar, Model # SJ8 or you can connect the units using their HDMI IN/ARC ports. Depending on how shallow the space is between the TV and the wall with the wall mount that you use, you may need to use angled connector adapters to make the necessary connections...^IFV

If an LG OLED TV supports Atmos is it necessary to purchase a sound bar that also supports Atmos? Or will a non-Atmos sound bar properly play the Atmos signal coming from the TV?

Asked by: WadeinUtah
Both the TV and the Sound Bar will need to support Dolby Atmos. THe TV has to be capable of decoding the Dolby Atmos soundtracks and the Sound Bar needs to be able to project it. In addition to traditional front-firing drivers, they feature upward-firing drivers that reflect sound down from the ceiling toward your listening position, adding height to the soundstage and creating overhead effects...^IFV

Can you tell me which LG rear wireless speakers are compatible with the SJ8 soundbar?

Asked by: Cdoyle19y6
Regrettably, there aren't any Rear Wireless Speaker Kits that are compatible with the LG 4.1 ch High Resolution Audio Sound Bar, Model # SJ8. The only available Rear Speaker Kit that we currently have is the LG 2.0 ch Sound Bar Wireless Rear Speaker Kit, Model # SPJ4-S which is only compatible with the LG SJ4Y and SJ5Y Sound Bar Models. You can add additional LG Music Flow Speakers to the SJ8 as outlined in your owner's manual on pages 31 - 33 but they will not give you 5.1 surround sound...^IFV
